n behalf of the staff and board of directors at the Delaware Center for Horticulture, welcome to the 39th Annual Rare Plant Auction® (RPA) – an evening of exquisite plants to benefit extraordinary programs.

For close to a year, dedicated groups of volunteers and staff have worked tirelessly to create what ultimately becomes the Rare Plant Auction®. Renowned plant experts hand-selected the more than 300 unique specimens on display tonight. Our event chair Lucinda Laird, vice chair Sally DeWees, and this year’s steering committee guided everything from the invitation to the food and helped recruit event sponsors. Our 2019 Celebrated Plant Expert Andrew Bunting worked to ensure his specialty, trademarked magnolias are available to bring home the highest bids. Honorary co-chairs Lloyd and Jeff Bove generously hosted this year’s Clivia Luncheon to kick off the day in style. And our staff and volunteers worked to weave it all together into a night of horticultural perfection. But all this means so much more than just one night of celebration. Your attendance and plant purchases this evening support all of DCH’s greening and education programs. Through DCH’s education programs for youth and adults, the Branches to Chances Return to Work Program, ecological landscapes, and our work in urban agriculture, we deliver programming that introduces people to the life-changing power of plants – a power that unites people, restores hope, and changes perspectives. Your contributions tonight and the dedication of our volunteers, sponsors, partners, and staff make this transformative work a reality in communities throughout Delaware. To everyone who makes this event possible, I express my heartfelt thanks. A special thank you to Wilmington Trust, our event sponsors and advertisers, and plant donors. And as always, a world of gratitude to our host sponsor, Longwood Gardens, for their support year after year. Enjoy the evening, and again, thank you for being a part of this horticultural tradition.

2019 RPA® Celebrated Plant Expert Andrew Bunting is the Vice President of Horticulture and Collections at the Atlanta Botanical Garden. Previously, he was Assistant Director of the Garden and Director of Plant Collections at the Chicago Botanic Garden. For 26 years prior, he was Curator at the Scott Arboretum of Swarthmore College, and from 1991-1992, he was curator at Chanticleer in Wayne, Pennsylvania. Andrew is the past president of the Magnolia Society International. He has published over 100 articles in American Gardener, Arnoldia, The Hybrid, Fine Gardening, The Magnolia Society Journal, Green Scene, and Organic Gardening. He has lectured extensively in the United States, as well as England, Belgium, Poland, and New Zealand. Andrew has participated in plant expeditions to China, Taiwan, and Vietnam. He is also the recipient of American Public Gardens Association (APGA) Professional Citation and received the Chanticleer Scholarship in Professional Development in 2010. Belvidere, his home garden in Swarthmore, Pennsylvania, has been featured in This Old House Magazine and The Wall Street Journal. Andrew published The Plant Lover’s Guide to Magnolias in April 2016. WHY ANDREW LOVES MAGNOLIAS — “When I was in high school, we lived in a split level house in Manhattan, Illinois. My room was basically cantilevered into the canopy of a mature saucer magnolia, Magnolia x soulangeana. Even in my youth, I appreciated the early spring blossoms, and this tree in particular opened my eyes to the beauty of flowering trees. In 1986, I started as a curatorial intern at the Scott Arboretum, where we had a large and mature magnolia collection with selections of M. stellata, M. x soulangeana, M. x loebneri and even some southern magnolias, Magnolia grandiflora. This is where my passion for the genus really exploded. Over the next nearly 30 years while I was curator at the Scott Arboretum of Swarthmore College, we grew our collection from 50 to 200 cultivars, adding many yellow cultivars, new species, etc. In fact, because of the breadth and depth of the collection, we received National Collection Accreditation through APGA. During the latter part of my career at Scott, I also became actively involved on the board of the Magnolia Society International and traveled to Colombia, Poland, and Sweden for international magnolia meetings. I was also fortunate to join plant expeditions to China, Taiwan, Vietnam, and the southeastern U.S. in search of rare magnolia species, witnessing firsthand the global diversity of these outstanding trees.” |9

THE PLANTS FEATURED PLANT Magnolia × brooklynensis ‘Judy Zuk’ This year’s featured plant is a rare and stunning specimen named for an acclaimed horticulturist with ties to our region. An alumna of the University of Delaware’s public garden administration program, Judy Zuk was director of Scott Arboretum at Swarthmore College before serving as president of the Brooklyn Botanic Gardens from 1990 to 2005. Named upon her retirement, this cultivar is known for glowing, deep yellow flowers with an intriguing purple flush. A tight, columnar form makes this vigorous, deciduous tree a stunning specimen with a height of up to 28 feet at maturity. Look Magnolia × brooklynensis ‘Judy Zuk’ for the multitude of blooms with a mild, fruity fragrance popping against foliage starting in mid-May. Share in Judy’s passion for magnolias and grow a piece of local history with this exceptional tree. Plant in full sun to part shade in a moist, slightly acidic, well-drained soil. Hardy to zone 5. GIFT PLANT Heuchera Dolce® ‘Apple Twist’ This year’s gift plant is a new Heuchera introduction that displays dramatic costume changes throughout the seasons. Newly emerging leaves have red veining. Chartreuse yellow leaves have wavy, rippled edges that mature to apple green. Long-blooming cream flowers attract butterflies and hummingbirds. Coral bells are easy to grow and blend well with other perennials in the landscape. They are Heuchera Dolce® ‘Apple Twist’ great used as an edging along paths, in containers, or fresh cut in bouquets. Also deer resistant and salt tolerant, this tried and true perennial grows 10 to 12 inches high, by 18 to 20 inches wide. Plant in part to full shade, average to fertile soil. Hardy to zone 4. SELECTED MAGNOLIAS Magnolia macrophylla var. ashei – This native dwarf form of the bigleaf magnolia grows into an upright, pyramidal tree between 12 and 20 feet tall. Ashei magnolia boasts spectacular deciduous leaves, the largest among its kind at two to three feet long. These turn to dark green with a blueMagnolia macrophylla var. ashei gray underside, creating a shady canopy at full maturity. In April and May, its astounding ivory flowers bloom on trees as young as three years old, showing off beguiling purple spots in their centers and reaching 10” to 15” in size. Post-bloom, look for brightly-colored seeds clinging to cone-like fruit from July to August. Plant in a spot with full sun to part shade and moist, well-drained soil. Hardy to zone 6. Magnolia × ‘Exotic Star’ – Renowned magnolia breeder Dennis Ledvina developed this striking hybrid of Magnolia grandiflora and Magnolia sieboldii. An evergreen, this hard-to-find tree will grow between 25 and 45 feet in height. ‘Exotic Star’ bursts with white blooms accented by vivid red-pink stamens from a young age, starting in June and continuing intermittently through summer. Hardy in zone 6 and above. Magnolia × brooklynensis ‘Lois’ – A late spring bloomer with fragrant, intense yellow flowers, this magnolia was the final addition to the Brooklyn Botanic Garden’s renowned magnolia breeding program, which has been discontinued. (The name is an homage to Lois Carswell, former chairman of the Board of Trustees there.) With its pyramidal shape and mature height of up to 30

| 11

THE PLANTS feet, ‘Lois’ makes an excellent border specimen, with plenty of blooms to cut and show off indoors, too. Plant in sun to part shade in moist, acidic, fertile soil. Hardy in zones 5 to 8. Magnolia × ‘Hot Flash’ – The deep golden, tulip-like blossoms on this hybrid of ‘M. Woodsman’ and ‘M. Elizabeth’ feature a flush of rosy pink at their base. They pop just as leaves are beginning to emerge around early May, attracting spectators and pollinators alike. This deciduous tree has an upright globe growth habit and will grow to between 20 and 30 feet tall at maturity. Hardy in zones 5 to 8. Magnolia soulangiana ‘Alexandrina’ – Also known as saucer magnolia, ‘Alexandrina’ blooms early. Its fragrant, deep purple-pink flowers with white centers appear in March or April before leaves have emerged, welcoming spring with a show of vivid color. It is adaptable as a shrub or street tree, but will grow 20 to 25 feet tall if allowed to do so.

Magnolia ‘Genie’

Magnolia soulangiana × liliiflora ‘Genie’ – Thank 15 years of breeding for the intense color and compact size of this deciduous hybrid, which tops out at 10 to 13 feet in height. Striking, black-red buds open into small, tulip-shaped blooms in shades of deep maroon purple to magenta rose, typically blooming between early spring and early summer. It is perfect to plant where space is limited or as a spectacular lawn specimen. Hardy in zones 5 to 9.

Magnolia ‘Butterflies’

Magnolia × ‘Butterflies’ – A cross between M. acuminata ‘Fertile Myrtle’ and M. denudata ‘Sawada’s Cream’ by renowned hybridizer Phil Savage, this specimen is a poised, neat-growing, upright magnolia that bears deep yellow flowers before the leaves emerge in the spring, keeping blooms safe from early spring frosts. The mature size is 25 feet tall by 12 feet wide. Plant in full sun to part shade in well-drained, moist, acidic soil. Hardy in zones 5 to 9.

Magnolia × ‘Daybreak’ – Avoid the heartbreak of frost damage with this specimen developed by North Carolina plant breeder August Kehr. It blooms in May, eight weeks later than most varieties, with highly fragrant, deep-pink flowers 10 inches across, even on very young plants. With a narrow, columnar habit, ‘Daybreak’ reaches 30 to 40 feet in height at full maturity and just 4 to 8 feet in width, making it a great garden accent or street tree. Hardy in zones 5 to 8. Magnolia virginiana ‘Green Mile’ – Sweetbay magnolias are known as grand, spreading shade trees featuring huge, creamy white flowers, and this one is no exception. Its extremely fragrant blooms appear through summer, offering a vivid contrast to lustrous, dark green leaves before pretty red fruits with orange seeds emerge in fall. In addition to attracting pollinators, this tree is a host for the larvae of both the tiger swallowtail butterfly and the sweetbay silkmoth. Mature specimens grow 35 feet tall and 15 feet wide. Hardy to zone 5. Magnolia virginiana var. australis ‘Perry Paige’ (Sweet Thing®) – This hardy dwarf evergreen is perfect if you love sweetbay magnolias but don’t have the space to accommodate their expansive size. Sweet Thing® tops out at 20 feet high and 10 feet wide at maturity, making it great for containers, low hedges, or border plantings. Its creamy white flowers bloom from early to late summer and feature a pleasant lemony aroma, starting out upright in shape before opening into a broad saucer. Plant this frost-tolerant specimen in full sun to part shade in moist soil. Hardy in zones 5 to 9. Magnolia × ‘Goldfinch’ – True to its cultivar name, this young bloomer shows off with pale yellow goblet-shaped flowers starting early in the season, so take care to plant yours in a warmer area where an early spring frost will not harm its blossoms. This mid-sized specimen with a pyramidal growth habit is hardy in zones 4 to 8.

THE PLANTS Magnolia figo ‘Stellar Ruby’ – Meet your new favorite flowering evergreen hedge specimen. Hybridized by the late Bill “Magnolia Man” Smith and introduced by Pat McCracken, this cross features unique blossoms that will give your garden a tropical look and feel. Star-shaped flowers in shades from deep fuchsia to dusky pink emerge in spring with a strong, pleasant scent of banana, then rebloom in late summer to early fall. With its glossy, deep green leaves, fast growth, and mature height of 10 to 15 feet, ‘Stellar Ruby’ can function as a great privacy screen all year round. Hardy in zones 7 to 9. Magnolia × loebneri ‘Ruth’ – Seeking a showy yet adaptable flowering tree that can stand up to pests? This Loebner magnolia is for you. ‘Ruth’ blooms from March to April, with pale pink buds that open to reveal large, star-like white blooms with a heady fragrance. While this specimen was bred for excellent pest resistance, take care to choose a planting site with full sun to part shade and well-drained soil that’s also well protected, as early spring frosts may damage tender petals. Hardy in zone 3 to 7. WET AND WILD: WATER TOLERANT SPECIES Baccharis halimifolia – Also known as sea myrtle or saltbush, this deciduous aster features graygreen oval leaves, with clusters of tiny flowers in white to pale green that turn to silvery, paintbrush-like seed heads in the fall perfect for floral arrangements. Plant this resilient shrub in full sun; it can tolerate both dry and wet conditions and makes a great seaside planting, thanks to its unique tolerance for salt spray. Also a great selection for roadsides. Hardy to zone 6. Betula nigra – Showy, colorful bark is the highlight of this native birch, which features shades of white, tan, and brown as bark peels from mature trunks. With stunning yellow leaves in fall and a height of up to 70 feet and width of up to 60 feet at maturity, river birch makes a lovely rain garden planting or shade tree. Plant in medium to wet acidic soil, as alkaline soils may cause chlorosis. Hardy to zone 4. Clethra alnifolia – This native shrub thrives near water, showing off with plumes of fragrant, white to pink flowers in high summer. With a height of 5 feet to 8 feet tall and up to 6 feet wide, it’s perfect for borders, privacy screens, and naturalistic landscapes. Plant in full sun for fuller foliage, and choose a site with moist, acidic soil, ideally near water. Hardy to zone 4. Cornus sericea – A shrub for all seasons, this specimen is perfect for wetter areas of your garden. The hallmark of Red Osier is its brilliant scarlet stems that give it wonderful winter interest. In the spring, lush green foliage emerges ahead of the blooms which are later than traditional dogwood trees. Large flat heads of white blooms arrive in May through June. The flower heads continue to be attractive, even in fruit, with large white colored fruits. It can reach a height of up to 12 feet, but should be pruned periodically to encourage the red color which is present on the newest growth.

THE PLANTS Itea virginica – Native to the southern United States, this deciduous to semi-evergreen shrub bears racemes of foamy, star-shaped white flowers in June. But Virginia sweetspire really wows in autumn, when its full, bushy foliage displays colors from golden and orange to deep crimson and maroon. Though its height maxes out around 6 feet, this multi-stemmed plant will spread and sucker, so give it room to grow. Hardy to zone 6. Nyssa sylvatica – Plant this easy-growing deciduous tree to create a food source and habitat for native wildlife: Its unshowy clusters of tiny, greenish-white flowers provide nectar to pollinators in late spring and early summer, while the subsequent small, dark blue fruits attract birds and other wildlife. Black gum thrives in moist, acidic soils but can tolerate drier conditions, and its height of up to 75 feet and spread of up to 30 feet at maturity make it a great shade tree or even street tree. Hardy to zone 3. Itea virginica

Magnolia virginiana – Also called swamp Magnolia, this semi-evergreen tree flowers with creamy white, lemon-scented blooms starting in June and continuing sporadically through the summer, making it a lovely patio plant. Long fruits with vivid red-orange fruits emerge in fall. These magnolias require acidic soils and do best in full sun - an ideal site will be protected from cold winter winds. Hardy to zone 5. Viburnum dentatum – Winter-hardy, vigorous, and low maintenance, this deciduous shrub makes a perfect hedge specimen. Butterflies and birds will flock to these plants and their flat-topped Magnolia virginiana corymbs of tiny white flowers in late spring and the drupes of blueblack fruits that pop against yellow, orange, or red foliage in fall. Arrowwood prefers moist, loamy soil, but can tolerate a wide range of moisture conditions. Hardy in zones 2 to 8. Acorus americanus – The semi-aquatic perennial herb sweetflag can be found near bodies of water throughout North America, thriving in rain gardens and boggy spots with full sun to light shade. Pale green flowers in the form of dense spikes appear in spring. Indigenous people have long utilized sweetflag’s rhizomes as medicine for a variety of conditions like nausea, anxiety, heartburn, and fatigue. Sweetflag is a vigorous spreader, ideal for retaining soil as a pond border. Hardy in zones 3 to 6. Asclepias incarnata – Also known as swamp milkweed, this herbaceous native perennial is known for vibrant clusters of pink to mauve blooms, which attract butterflies and hummingbirds to feed on their nectar. The species also serves as a key food source for monarch and queen butterfly larvae. Swamp milkweed is deer-resistant and can tolerate sites with heavy clay soils. Hardy in zones 3 to 6. Iris versicolor – A versatile and vigorous perennial wildflower that is resistant to deer and other herbivores, blue flag thrives in marshes, swamps, along the shores of creeks and ponds, and bordering Asclepias incarnata wetland forests. Vivid violet blooms, with yellow blotches bordered by white, pop against sword-shaped, deep green leaves in May and June. Plant this low-growing, low-maintenance specimen in full sun to part shade. Hardy in zones 2 to 7.

THE PLANTS Lobelia cardinalis – Cardinal flower has spikes of fiery crimson blooms, which attract wild species like ruby-throated hummingbirds, swallowtails, and sulfur butterflies from late summer through early autumn. Plant this deer-resistant specimen in moist, humus-rich soil, ideally with at least part shade. Hardy in zones 3 to 9. Verbena hastata – A native perennial, blue vervain is both beautiful and medicinal, traditionally used to treat respiratory ailments, depression, and symptoms of menopause, among other indications. Spikes of small, tube-shaped purple-blue flowers in a candelabra Lobelia cardinalis formation appear midsummer, attracting a variety of pollinators. Deadhead after blooming to promote a branching, bushier shape and cut down on reseeding to prevent spread. Plant in a spot with full to part sun and moist or wet soil — this species can tolerate moderate levels of salt, too. Hardy in zones 3 to 9. NOMEN NUDUM Performing an elegant fan dance this naughty specimen has been giving us a peep show without our knowledge. Nomen nudem is Latin for naked name and is the term used when a botanical name is not properly supported with herbarium specimens and proper scientific publication. The following specimen is available in the horticultural trade but is not officially named within the scientific community. Pilea glauca – This trailing groundcover is something of a mystery plant: its botanic name in everyday use, Pilea glauca, has never been published and therefore lacks legitimacy in horticultural circles. And Pilea glaucophylla, as it’s sometimes known, is quite a different plant. But the species, commonly known as silver sprinkles or gray artillery plant, has also been identified as Pilea libanensis of Cuba, according to David Scherberich of France’s Jardin Botanique de la Ville de Lyon, likely its true botanical name. Its leaves will lose their “sparkle” when the plant needs water, then return once it’s been hydrated. It’s hardy in zones 10a to 12, so it is best to keep this specimen inside as a trailing hanging basket or houseplant in a spot with bright shade in cooler climates. SELECTED SPECIMENS Prunus cerasifera ‘NCPR-7’ (Purple Plunge®) – A deciduous weeping plum developed by North Carolina State University’s J.C. Raulston Arboretum, Purple Plunge® features a vivid purple foliage and a unique, pendulous branching habit. This adaptable and quick-growing small tree has large, fragrant blush pink flowers in its second year that serve as the main attraction, as this tree has not produced fruit in 10 years. Feature this specimen as a showy border plant or use it to add height and drama to ornamental beds. Hardy in zones 7 to 11. Rosa (Spring Hill’s Freedom Series) – Have you always wanted a rose hedgerow but didn’t want to deal with maintaining disease-prone foliage? This groundbreaking line of disease-resistant shrub roses created by renowned breeders Christian Bedard and Dr. Keith Zary exclusively for Spring Hill Nursery is for you. This specimen, with incredibly clean foliage and superior disease resistance improves on the original Spring Hill Freedom line, features old-fashioned blooms in red, yellow, orange, pink, or coral that appear from late spring to fall. Plant in full sun to part shade 3 feet apart for your own colorful, low-maintenance hedge. Hardy in zones 4 to 10. Dysosma ‘Red Panda’ – This highly coveted, hard-to-find hybrid mayapple features large, copper-colored leaves and red flowers in spring, with foliage infused with green through the summer. Plant this perennial in a spot with partial to full shade and consistently moist soil, then collect dry seed heads to direct sow outdoors in fall. Hardy to zone 7b.

THE PLANTS Ficus carica ‘Olympian’ – This pint-sized cultivar of a hardier-than-usual fig is perfect for smaller spaces and home gardens, as it typically grows a third to half as tall as the full-sized version, which can reach up to 10 feet. This variety will produce deep purple, Black Mission-like fruits both early and late in the season in warmer climates, especially when planted in full sun; it will produce a single crop in cooler climates and bear fewer fruits if planted in shade. Expect fruit by the second or third year. Hardy in zones 6 to 9. Clivia miniata ‘Harry’s Light of Buddha’ – A variegated Clivia that features showy, vivid to pale orange blooms with rich yellow centers, originally from China. Its green leaves feature the plant’s signature broadly transverse tiger-striping with a creamy yellow shade, similar to the Akebono variety but with broader, shorter foliage and less clearly defined bands that almost look as if the plant is lit from within. Plant in a low-pH potting soil as a houseplant, and don’t over-fertilize to maintain this stunning specimen’s unique variegated coloring. CUTTING-EDGE Hot off the press! Be the envy of your garden club and get your hands on some of the newest introductions to the market. The following specimens represent years of work to bring you the best and brightest plants for your garden. Prunella vulgaris ‘Magdalena’ – New for 2019, this highly adaptable varietal of self-heal features blooms in two shades of purple emerging in clusters of short, four-sided flower spikes around midJune. Its semi-evergreen foliage is fingered and pointed, with a bright green shade in warm weather and purple highlights appearing during the cool months. Plant this native in full sun; it can tolerate most soil types. Pennisetum alopecuroides ‘Yellow Ribbons’ – This brand new cultivar of golden fountain grass has a size and growth habit similar to ‘Hameln,’ spreading up to 2.5’ in width and height, but its foliage changes from bright gold to a shade of chartreuse yellow through the summer season. Its plumes, a pale tan in color, appear in August and bloom through October on 2-foot-high stems and can be cut and dried for indoor decor. Plant in full sun to part shade and medium to wet soils as ground cover or a rain garden addition. Hardy in zones 5 to 9. Sedum ‘Pillow Talk’ – Easy to grow in full sun and average soil, this relatively new stonecrop cultivar is more resistant to fungal diseases like Rhizoctonia root rot. Mass this perennial in small areas as ground cover or for borders to show off 6” heads of bicolor flowers in pink and magenta appearing in late summer. ‘Pillow Talk’ features reddish-purple stems and succulent gray-green foliage, which can redden on the edges as the season goes on. A good drought-tolerant specimen. Hardy in zones 4 to 9. Sedum ‘Sunset Boulevard’ – This new addition makes a showy addition to autumn container plantings and ornamental borders alike. A sister cultivar to ‘Pillow Talk’, vivid heads of blooms in a deep raspberry-magenta shade appear on this showy sedum from August to September. In fall, its red stems sport showy foliage in shades of lime green, orange, and red, with wine-colored seed heads on display. Plant in full sun. Hardy in zones 4 to 9.

THE PLANTS Sedum ‘Lime Joy’ – A vigorous grower, this particularly striking stonecrop saves its showiest blooms for autumn. Lime green buds similar to hydrangea buds appear against gray-green foliage by high summer; in September, they open with 6”-8” domed masses of bi-color blooms in magenta and pink on reddish-purple stems. Plant in full sun in a site with well-drained soil. Phlox ‘Wanda’ – Supposedly named for the home gardener who found this naturally occurring hybrid phlox in her garden before giving seeds to renowned horticulturist Dr. Allan Armitage, this quick-blooming cultivar offers increased disease and pest resistance. Its long-lasting blooms are a vibrant shade of magenta that appear from mid-spring to fall. It’s particularly in demand in horticultural circles for its ease of cultivation and for flowering while growing new roots. Plant in full to part sun with well-drained soil. Hardy in zones 5 to 10. Lysimachia lanceolata var. purpurea – Known as purple lance-leaved loosestrife, this tough, heat-tolerant native does triple duty in the garden, suppressing weeds as low-maintenance groundcover while attracting pollinators and providing ornamental interest with creeping, wine-colored foliage and tiny star-shaped yellow flowers that appear in summer. Plant in full to part sun; though it can tolerate a wide range of moisture levels, it is particularly well-suited to dry, sunny spots. This is not the invasive purple loosestrife (Lytrhum salicaria). Hardy in zones 4 to 8. Penstemon pinifolius ‘P019S’ SteppeSuns™ Sunset Glow – More than two decades in the making, this drought-loving, mounding groundcover plant attracts hummingbirds and pollinators with trumpet-shaped blooms that pop against its shiny green foliage from late spring and into summer. Plants grow 12”-18” high and 18”- 24” wide. Good for cut flowers, too. Hardy in zones 4 to 8.

Acer × pseudosieboldiaum ‘IslID’ (Ice Dragon™)

Acer × pseudosieboldiaum ‘IslID’ (Ice Dragon™) – A new addition to the Jack Frost® series of small, cold-hardy Japanese maples, Ice Dragon™ was bred with the refined qualities of less hardy cultivars while tolerating zone 4 winters. In spring, its finely divided leaves appear with a blush of orange-red, then mature into green as the season warms. Heat- and sun-tolerant foliage in summer changes to kaleidoscopic orange, yellow and red in autumn before falling to reveal winter interest in the form of an attractive undulating branching habit. Plant in full sun to part shade. Mature specimens will reach 8 feet in height and 10 feet in width.

THE CHANTICLEER PALETTE One of the Delaware Valley’s most notable gardens, Chanticleer continually stuns visitors with its breathtaking displays. The following selections will be featured in their perennial gardens this season. Enjoy a small piece of elegance in your own garden.

Salvia argentea

Salvia argentea – A living sculpture, this salvia adds a strong architectural element and will leave your guests amazed with its silvery foliage. The broad leaves have a heavily textured edge that gently undulates. The pewter-green leaves are covered with a dense layer of velvety soft hairs. Forming a large clumping rosette, the plant should not be allowed to go to flower. The development of the flower spike will make the plant leggy and it will die back after it goes to seed. This plant has been given the Royal Horticulture Society’s prestigious Award of Garden Merit.

Leonurus cardiaca ‘Grobbebol’ – A member of the mint family, this hardy perennial can be a bit aggressive when left unchecked. Its resilient nature makes it perfect for container planting. Mass planted in a large ornamental urn, this specimen can be placed around

THE PLANTS a patio or along a boulevard to best make use of its fragrant foliage. Lush foliage carries you into the summer months before blooming in late July and August, a season typically harsh on other flowering plants. Place the containers in a protected location to over-winter, and return to place as the spring temperatures increase. Dianthus japonicus – The Japanese dianthus is a specimen like no other. This plant has the distinction of stumping even the most well-versed horticulturist when they have attempted to identify it. A biennial in our climate, this dianthus can be semi-evergreen in warmer climates. The leaves are a glossy deep green and feature a silvery green color, unlike other dianthus that are fringier and lance-like in texture. The blooms arrive later in summer and are a delicate clear pink. Combine with early blooming dianthus for continued color throughout the season. Aquilegia olympica – The clear purple and white blooms of this Columbine are hard to resist. Native to southern Russia through Turkey and Iran, this specimen features a strong upright habit and wonderfully textured fringy leaves. The wide nodding blooms are the star of the show and pair well with the steely tones of the Salvia argentea. Aquilegia derives its name from the characteristic spurs at the base of the petals that are reminiscent of eagle’s talons. Gaura lindheimeri ‘Cool Breeze’ – ‘Cool Breeze’ certainly lives up to its name. This wonderful selection produces pure white flowers that feature crisp white petals and white stamens. Traditional white varieties still had pink stamens. This specimen is strongly floriferous and will bloom from early summer until first frost. Gaura’s light and airy form is excellent for tying together stronger more structural elements in the garden. It is useful for giving movement to formal gardens, and the flowers are perfect for cut arrangements. NOTABLE BREEDERS The botanical wonders of the world are highly coveted treasures, but just as gold and silver ore can be refined into jewelry and currency, so can plants be transformed into something more than they are in the wild. Plant breeding has been going on for longer than one might imagine, but it has really taken hold in modern times as selected traits make specimens more and more desirable. Featured below are some of the botanical artists creating new and inspired creations through their breeding efforts.

Rhododendron arborescens

Clivia miniata (Interspecific Hybrid)

Rhododendron arborescens (short form) – From the Appalachian Mountains of Franklin County, North Carolina comes a wonderful natural variety of Rhododendron arborescens. This seed-grown selection was introduced by horticulturist and plantsman Jim Plyler. Jim has a passion for seeing native plants growing in the wild and making informed propagation choices based on those observations. This specimen was immediately known to be special as it was only half the height of typical individuals of R. arborescens. Perfect for smaller gardens, it retains all of the stunning attributes of its fullsized form. Crisp white flowers with jewel-red filaments emerge in June, creating stark contrast against its glossy dark green foliage. Commonly referred to as the sweet azalea for its fragrance, R. arborescens is a must-have for any garden. Clivia miniata (Interspecific Hybrid) – An exceedingly rare opportunity to take home a unique treasure from the Longwood Gardens Clivia breeding program. Dr. Robert Armstrong launched the program in 1976 and has produced some of the most stunning Clivia currently available, the most recent being the green tinged cultivar named Clivia miniata ‘Longwood Winter Green’ which was named by

THE PLANTS voting at the 2019 Philadelphia Flower Show. The main objective of the breeding program was to produce increasingly showy blooming specimens, but during the search for these blooming beauties, other interesting treats arose. The specimen offered here is a non-flowering type prized for its foliage. Ideal for any indoor garden, this compact Clivia features curious oblong, waffle-textured leaves. Its exact parentage is unknown but is believed to be the cross of a painted-face type with an unknown parent. A wonderful must-have selection for any diehard Clivia collector. × Mangave – Plant breeders are akin to great painters in their ability to see the potential of a blank canvas. Hans Hansen has done that with the stunning beauties known as mangave. What was originally circulated as a horticultural oddity has become a sensational suite of plants with every variable of color and form. Mangave are intergeneric hybrids between Manfreda and Agave. The strong and sometimes stark attributes of agave are softened by the vigor and adaptability of manfreda, but the two equally affect each other providing truly stunning displays. With each successive generation of plants, Hans discovers more and more favorable traits. The imagination is the industry’s best friend, and the reason we need talented breeders like Hans. The twelve mangave below feature a wide cross-section of the wonders that have come from his efforts. ‘Bad Hair Day’ – Stylists beware! ‘Bad Hair Day’ is too hot to handle. A rich medium green leaf features elegant reddish spots with blush tips. Many mangave retain the strong upright forms of agave. ‘Bad Hair Day’ though has highly relaxed thin strap-like leaves reminiscent of the common spider plant (Chlorophytum.) Perfect for hanging baskets or face planters. ‘Crazy Cowlick’ – The punk rock cousin to ‘Bad Hair Day’, ‘Crazy Cowlick’ turns it up a notch. The low rosette features the same lush green and red tones, but with a bite more closely resembling a traditional agave. Coppery marginal spikes and terminal spine adorn this wild child. The open roads and full sun are a necessity for this specimen as it will lose its coloration in too much shade. ‘Crazy Cowlick’

‘Freckles & Speckles’

‘Lavender Lady’

‘Freckles & Speckles’ – A bit of a tomboy, ‘Freckles and Speckles’ will warm your heart with its playful form and color. Anne of Green Gables jumped to mind when looking at this specimen. Featuring some of the same tones and form as ‘Lavender Lady,’ but with a freer spirit that loves the sun and needs it to maintain its characteristic freckles. Just as Anne quickly became friends with the local girls, so will ‘Freckles and Speckles’ with your garden or planted succulent container. ‘Inkblot’ – The itsy bitsy spider climbed into our hearts with this uniquely attractive selection. The dark speckled leaves of ‘Inkblot’ have a strong arching habit and low form giving it the appearance of a great tarantula. This spiny beast is more bark than bite. While it appears to have the aggressive qualities of agave, it is soft and playful to the touch. A perfect container specimen, ‘Inkblot’ is a must-have for those with a more macabre demeanor. ‘Lavender Lady’ – This stunning beauty looks like she’s stepped straight out of the Golden Age of Hollywood. Smokey blues and purples are the predominant color of this leading lady, and they do not disappoint. A strong upright form similar to that of Agave attenuata gives ‘Lavender Lady’ a timeless elegance. The fine-toothed margin terminates with a delicate copper colored spine. ‘Lavender Lady’ makes for an attractive specimen plant perfect for a formal garden. Plant in fluted cast iron urns to line a formal avenue.

Josephine Bayard Interiors (formerly Plain & Fancy Interiors)


THE PLANTS ‘Man of Steel’ – A knight in shining armor will defend your garden from any intruders. The long thin leaves maintain a flat sword shape with terminal spine. The blue-green color of the leaves is transformed to a steely color with a silver wax coating on the leaves. Because of its even color and texture, it is often paired with ‘Lavender Lady.’ ‘Man of Steel’ is ideal for mass plantings to provide a silvery backdrop to highlight specimen plants in a formal garden. ‘Man of Steel’

‘Mayan Queen’

‘Pineapple Express’

‘Mayan Queen’ – A crown jewel for any garden, this specimen takes ‘Lavender Lady’ from a Hollywood bombshell to a Glamazon queen. ‘Mayan Queen’ features strongly textured leaves with a distinct wavy edge and toothed margin. The distinct lavender color of ‘Lavender Lady’ is enhanced with deep burgundy spots that enhance the exotic appeal of this specimen. Ideal as a featured plant in a garden space, it would pair well with × Mangave ‘Mission to Mars.’ ‘Moonglow’ – Like a sculpture of living agate, ‘Moonglow’ will capture a piece of the night sky in your garden. The silvery lanceshaped leaves maintain a strong straight form making them look like rays of light. Large spots of deep bluish purple cover the length of the leaves. Drift plant with × Mangave ‘Blue Dart,’ ‘Catch a Wave,’ and ‘Man of Steel’ to transform your garden into a stunning lunar landscape. ‘Pineapple Express’ – If you like getting caught in the rain, then ‘Pineapple Express’ is the mangave for you! Feature in a gloss diamond pattern container for a stunning sculptural effect. The tight upright form features stiff minty green leaves overlaid with a dark bluish cast. Darker splotches give the leaves a subtle marbled effect. Pair with ‘Falling Waters’ for a fabulous high low effect.

‘Spotty Dotty’ – Head out for a night on the town with ‘Spotty Dotty.’ This wild gal is ‘Freckles and Speckles’ meets ‘Crazy Cowlick.’ The lush green leaves feature a sensual curvy margin with dark spots resembling a leopard print top, perfect for hitting the club. Gentle spines on the leaf margins give this vixen a bit of a bite, but you know you like that. The full form of the rosette makes this specimen perfect for container planting. Give this girl a sweet treat paired with ‘Cherry Chocolate Chip’ and ‘Mint Chocolate Chip.’ ‘Tooth Fairy’ – Not all fairies play nice, but you’ll love this wickedly playful sprite. This specimen heavily shows its agave parentage being highly reminiscent of some hybrid agave. The dense rosette features a silvery blue green color edged with multicolored yellow-cinnamon orange teeth, and wavy terminal spine perfectly fit for the crown of a fairy queen. Perfect as a focal specimen in a mixed succulent container, paired with frosty blue Echeveria spp. ‘Whale Tail’ – Cause a splash with simple yet elegant specimen. The gently arching leaves are flat at the base and gently curl towards their terminal spine. Featuring an even silvery blue color this specimen is perfect to join the likes of ‘Aztec King’ and ‘Purple People Eater.’ Pair this trio in funky modern containers for a new take on the classical formal garden. Excellent for a city garden or balcony.

300+ varieties of native plants

THE PLANTS Phlox Earlibeauty® – From the wilds of the Northeastern US comes some truly resilient yet beautiful Phlox hybrids. Charles Oliver of the Primrose Path in Scottsdale, Pennsylvania has spent the last several decades breeding some amazing Heuchera and Tiarella hybrids. His latest endeavor is focusing on a new series of phlox that are unlike any currently on the market. The Earlibeauty Series brings you a collection of phlox that hit the ground running, blooming late spring to early summer, a time when most traditional phlox are only beginning to grow. These beauties are not one hit wonders and will often rebloom in late summer giving you an endless show. The phlox in this series are vigorous growers and highly disease resistant. This could be due in part to where the nursery is situated. Charles describes Southeastern Pennsylvania as combining “…extremes of heat and cold with unreliable summer rainfall and winter snow.” An honest statement about the region, but a fact that has worked in his favor. Customers have noted better hardiness of specimens selected from the Primrose Path. Phlox ‘Solar Flare’ Earlibeauty® – ‘Solar Flare’ is certainly worthy of its name. The stunning rounded panicles of large bi-color flowers won’t cave under the pressure of the roasting heat of a Mid-Atlantic summer. Featuring a strong mounded form, this beauty will be a stand-out in any garden.

Phlox ‘Solar Flare’ Earlibeauty®

Phlox ‘Rose Bouquet’ Earlibeauty®

Phlox ‘Daughter of Pearl’ Earlibeauty® – ‘Daughter of Pearl’ may seem demure, but she’s as feisty as any in the Earlibeauty series. Dark glossy leaves are slightly pointed, perfectly framing the large glowing white conical panicles. The 1-inch wide flowers feature a slight tinge of purple at their center. A perfect selection for a monochrome or formal garden. Phlox ‘Rose Bouquet’ Earlibeauty® – A beautiful bouquet brightens any garden, and ‘Rose Bouquet’ will not disappoint. The lovely soft pink blooms balance atop lush medium green foliage. As with all the phlox in this series the fragrance is not to be overlooked. Plant close to your patio for a sweet treat on a warm day. Attractive to butterflies and hummingbird moths, your garden will be transformed into a fairy wonderland.

Pachysandra axillaris ‘Windcliff Fragrant’ – Well known for his fabulous Heronswood Nursery in the Pacific Northwest, Dan Hinkley is a jack of all trades in the horticultural world. Throughout most of his life he has traveled the world, particularly in Asia, searching for the best rare and unusual plants to propagate for American gardens. As with the other horticulturists featured here, it is Dan’s ability for observation and his vision for plants that has made him so exceptional in the horticultural world. In 2009, Monrovia Growers launched a collection to highlight the fruits of his labor, the best of over 25 years of collecting. To capture even a tiny amount of what Dan has accomplished is more than can be covered in several volumes. Featured here is a Pachysandra axillaris ‘Windcliff Fragrant’ collection of Dan’s plants from the Monrovia collection. The ‘Windcliff Fragrant’ pachysandra is a stunning specimen that we just had to share with you. Pachysandra has a love-hate relationship with many gardeners. Once loved for its resilience and rapid growth rate, gardeners are now held hostage to its brutish ways. Because of its vigor, it can often overtake and out compete the balance of a perfect shade garden. Native Allegheny spurge is a wonderful alternative, but it can be slow to establish. ‘Windcliff Fragrant’ is the best of both worlds. It has a faster growth rate than native species but will not crowd out your other woodland treasures. Blooming in winter, the delicate white flowers are a fragrant delight and will have you tearing out your old pachysandra to make room for this treasure.

THE PLANTS IN MEMORIAM David Austin OBE (1926-2018) – Critics initially dismissed his early efforts saying that no one would buy the roses he was producing, but 60 years later nothing could be further from the truth. David Austin Roses® are some of the most sought-after roses currently on the market and set the benchmark for modern rose breeding. To date, his roses have won 24 awards from the prestigious Chelsea Flower Show in London. David Austin Roses® David loved his roses and was forever making notes for their improvement. He is noted as saying, “Every time I make a cross, I think there is always something more beautiful to come.” His roses were not initially successful and his optimism for producing better roses carried him through until he hit commercial success in 1983, nearly 14 years after his first introduction ‘Constance Spry.’ One of the main notable signatures of his roses is their often-literary names. Senior rosarian Michael Marriott at David Austin Roses® told The New York Times that David would say, “…the easiest way to kill a rose was to give it a bad name.” A tour de force, David’s roses combine all the best qualities of old and new roses, making them an irresistible choice for many gardeners. Offered here is a selection of three of his roses from Overdevest Nurseries, LP and a gift card from David Austin Roses®. William “Bill” Frederick (1926-2018) – A native Delawarean, Bill was a professional landscape architect and avid gardener. His passion for plants permeated every aspect of his life and inspired him to published three books, the most recent of which details the development of his personal garden over the course of 50 years. However, of the three, he is probably best known for his first book, 100 Great Garden Plants in which he details some of his favorite garden plants.

“A gardener, by my definition, is anyone whose curiosity has been piqued by even a single living plant, and who feels even the slightest urge to experience the joy of placing a few plants together in the earth to achieve an effect.” – 100 Great Garden Plants The above quote is from the introduction and is particularly telling. For Bill, everyone could be a gardener as much or as little as they could, with no formal training needed. Through and through, a simple love of plants is all that is required. The following collection is based on one of his favorite plants, Acer griseum, the paperbark maple. It plays on the colors of the cinnamon bark and brilliant fall color, lighting your garden with wonderful flame colors throughout all 4 seasons. Special thanks to Nancy Frederick for this inspiring collection of plant ideas. Acer griseum – The paperbark maple is Bill’s highest voted all-season small patio tree, and his accolades for this tree are certainly warranted. The delicately flaking bark appears even in young specimens and only gets better with age. The mature size of this tree makes it perfect for a single specimen planting, or to Acer griseum be used for planting a formal avenue. As it grows it maintains a strong lollipop shape with strong open branching. The architectural appeal is only enhanced by its coppery cinnamon bark, and rich green leaves. The lush foliage comes into full strength in the fall with brilliant cherry red and flame orange colors.

THE PLANTS Hamamelis × intermedia ‘Jelena’ – The queen of witch hazels, ‘Jelena’ will keep you warm through those last few weeks of winter. The filamentous petals of witch hazels are transformed in this cultivar to a brilliant coppery orange. The warmth of this specimen will signal the rebirth of spring and the wonders to come in the following months. ‘Jelena’ has a wonderful open, vaseshape branching structure and medium height making it the perfect accompaniment for the paperbark maple and Rhododendron ‘Mount Saint Helens.’ Bill considers ‘Jelena’ the finest of all witch hazels and recommends planting it with a background of evergreens to fully showcase her fine flowers. He also recommends mass planting a myriad of witch hazel cultivars for a breathtaking display of color mid-winter into spring. Rhododendron ‘Mt. Saint Helens’ – A beautiful hybrid from Girard Nurseries ‘Mt. Saint Helens’ picks up on the smaller size of the paperbark maple reaching a mature height of around 6 feet. It also has a coarser architectural form, allowing it to stand out from finer textured garden plantings. As with any azalea, the true stars are its blooms. This specimen features blooms on the larger side up to 2.5 inches across. The lightly scented clear-coral colored blooms are tinged with a golden-orange color on their upper petal. April showers bring May flowers, and this azalea certainly will not disappoint blooming around the end of April. Campsis × tagliabuana ‘Madam Galen’ – A stunning specimen in its own right, ‘Madam Galen’ did not make the cut to be one of Bill’s 100 great garden plants. She did, however, garner an honorable mention for her versatility in the landscape. Elegant compound leaves provide a strong architectural flare and serve as a backdrop for the vibrant peachy orange flower clusters. Left to grow naturally, this specimen will blend into its environment providing splashes of color in late summer. Where ‘Madam Galen’ truly shines is on an arbor or trellis. A sturdy pergola over a patio space is the perfect place to plant this vine. Not only will it provide shade, but the attractive orange blooms are hummingbird magnets. Rhus aromatica ‘Gro-Low’ – The downside of the brilliant color of Euonymus alatus (burning bush) is its highly invasive nature. Favored for its strong architectural tones, which Bill described as gaunt and muscled, Rhus typhina ‘Laciniata’ provides some brilliant color that could replace the burning bush. The collection at hand is ideally suited for a medium to intimate garden space and needs a softer Rhus to fill that requirement. Rhus aromatica is perfectly suited for the task and serves as a wonderful replacement for the burning bush. This low-growing spreading shrub displays brilliant fireworks of color in the fall with brighter orange and yellow tones that play off of the richer red tones of the paperbark maple. This sumac is perfect for planting in the back of your garden, its lush green, lightly scented foliage a subtle backdrop to a beautiful garden space.

THE PLANTS TROPICAL WONDERS Atlanta Botanical Garden is home to some truly special tropical specimens. The Rare and Dwarf Conifer Collection holds some of the world’s most rare and unusual cone-bearing trees. Stepping into the conservatory you are met by dazzling displays from every corner of the world. These specimens will bring a touch of exotic mystery to your conservatory, but beyond that they hold remarkable stories that offer a glimpse into the monumental research and conservation efforts that are conducted through the garden and its research partners. RARE CONIFERS Juniperus bermudiana – The Bermuda Cedar has seen a rough life but is on its way to recovery. As early as the 1600’s, the timber was prized for shipbuilding and housing. Several acts of legislation have been passed throughout its history in order to help conserve the species, but it was not until the mid-1800’s that it received a break due to the decline in shipbuilding and the importation of cheaper lumber. It was able to recover for another century before the accidental introduction of cedar scale decimated the population. With the help of scale resistant cultivars, the national tree Juniperus bermudiana of Bermuda’s population is once again recovering. Summer hardy here this specimen features a stunning exfoliating bark that gives the trunk wonderful stripes of blue and grey. The foliage is reminiscent of a mix between the ‘Carolina Sapphire’ cypress and our native juniper, delicately blue-green and wonderfully structured. This specimen is sure to be the star of your summer patio. Cupressus vietnamensis – A rare treasure from the cloud forests of Vietnam. C. vietnamensis was an exciting discovery for taxonomists in 2001 as it was the first new conifer discovered since Wollemia in 1994. Approximately 1,000 individuals are known in the wild, and in cultivation, only 17 institutions have it represented in their collections. The growth of this specimen is very architectural making it the perfect focal point for any conifer collection. When young, specimens display a close pyramidal shape, but widen to an elegant flat crown when mature. Lightly exfoliating bark Cupressus vietnamensis displays wonderful tones of reds and purples, maturing to silvers and browns. The needles are a lovely medium green and contrast well against the darker trunk. Summer hardy in our zone this specimen is perfect for a large conservatory or container planting on your patio.

Ceratostema rauhii

Selenicereus wittii

Ceratostema rauhii – An epiphytic member of the blueberry family, this trailing treasure will make you the envy of your friends. The long pendulous branches can reach up to 6 feet in length forming an elegant curtain of green. The slender green leaves are reminiscent of dragon scales and are arranged similarly to donkey’s tail sedum. The real star of the show are its ruby colored flowers that run the length of the branches. From the cloud forests of Peru, this specimen can be a bit of a diva when it comes to moisture, but is well worth the effort. It is best grown in an orchid crate in a similar mix as used for growing Nepenthes. With a little bit of love, this plant will love you back ten-fold. Selenicereus wittii – The rare Amazonian moonflower at first glance appears unassuming, save for one night a year when its spectacular blooms open. This elusive beauty found a prominent place in the heart of Margaret Mee. A sculpture artist by training, Mee was unable to find work in England at which time she decided to travel abroad to the Amazon rainforest. It was there that she would begin her legacy of botanical illustration. Her illustration of S. wittii differs from her others in that it shows the plant in relation to its surroundings. This species is an epiphyte and its survival is contingent upon its host plant. Mee was a great advocate for conserving the natural beauty of the Amazon so that treasures like the moonflower were not lost. Deep scarlet leaves cling tightly to the host plant, providing a striking background for the fragrant, creamy white flowers that bloom at night once a year. The book The Flowering Amazon: Margaret Mee Paintings will be featured with this specimen.

and Jeff Bove


loyd and Jeff Bove are passionate about their Burrows Run Farm, which has been carefully guided by the same family’s hands since the 1960s. Jeff, an attorney and musician, and Lloyd, a teacher and gardener, have for 27 years been stewards of their old farm property, which is part of an original 100-acre property now protected by numerous conservation easements. Mature and sturdy specimen trees, including a blue atlas cedar, continue to anchor the property and provide a marvelous counterpoint to the current naturalistic approach to gardening. In fact, many of the specimen trees and shrubs were acquired at the Rare Plant Auction® over the years. The garden has taught them both a great deal about creating an environmental sanctuary that sustains many animal and bird species.
