ooking for an a-maze-ing way to explore plant life and the living treasures? Test your knowledge, exercise your curiosity and challenge your climbingrunning-jumping prowess at Mission Botanica, a life-sized interactive maze exhibit that opens June 11 and runs through summer.

“The maze gives families and groups a mission, so they start at the beginning, spin a mission wheel and the fun begins!” says Eva Rodriguez, manager of interpretive services at Holden Forests & Gardens (HF&G). Every mission offers an opportunity to “meet” a dozen native plants and trees found within the Arboretum. “We are introducing and sharing the wild and wonderful world of plants with Northeast Ohio, and that is really exciting to us,” Rodriguez relates, noting that the maze missions include questions to answer that help you decide which direction to turn. “As you go through the pathways, you stop at these decision points — and if you get a wrong answer, you hit a dead end,” Rodriguez explains. “If you get the question right, you get to continue exploring.”

8   FORESTS & GARDENS

The 20- to 30-minute experience for all ages is presented by Minotaur Mazes, which creates interactive worldwide traveling exhibitions at places like zoos and nature centers. This is the first time the exhibit is focusing on plants and trees that are native to our region. Inside the maze, which is open rain or shine, there are fun photo opportunities with selfie stations — and the rest is under wraps until you explore. “The really cool part is that the 12 plants are found all over our grounds, so we encourage everyone to search for these plants once they learn about them,” Rodriguez says.

Plant a Difference this Arbor Day The 150th celebration of our nation’s tree-focused holiday is an ideal time to make the People for Trees pledge. By Kristen Hampshire

eaningful change starts in our own back yards — our neighborhoods — and simple acts like planting and caring for a tree can help counter the impact of climate change, provide shade, clean the air of toxins and increase property value.

As we celebrate the 150th anniversary of Arbor Day, Holden Forests & Gardens (HF&G) invites Northeast Ohio communities to embrace and join our campaign: People for Trees, the movement that highlights our work in tree care with a goal to plant more than 15,000 trees across the region by 2025. Already, more than 1,000 people committed to planting more than 4,500 trees. “The 150th anniversary of Arbor Day is cause for celebration, especially given the significant need for reforesting Cleveland and Northeast Ohio,” says Jill Koski, president and CEO of HF&G. “The impacts of climate change are becoming even more challenging and pressing, and planting trees is so essential.” Arbor Day is a signature holiday in the arboretum world, Koski adds. “It’s so easy to take trees for granted, and it’s the one day a year where trees are really the focus.” Trees are always center stage for us, and conservation and research efforts to promote tree health are founding principles of the organization. The coinciding of Arbor Day’s sesquicentennial birthday and the People for Trees initiative calls attention to a vital need.

“Trees on privately-owned land provide benefits for the entire community.”

— Sandra Albro

“Many of us don’t realize how important things are in everyday life until they go missing,” Koski says of a diminishing tree canopy. “People for Trees is about raising awareness every day, and through our deep membership and visitor base, individuals can make a difference and do something to make change,” she says. Holden Forests & Gardens community foresters planting trees in the community.

Growing a Positive Impact Not only does People for Trees empower people to plant and care for their own trees, it’s also a platform for science and conservation teams at HF&G to share more learning and cuttingedge discoveries with the community. “We are hoping for Arbor Day, people will take a pledge to plant a tree in their yard,” says Sandra Albro, HF&G’s director of community partnerships, sharing a goal of reaching 3,000 trees planted through the holiday.

Anyone Can Make a Pledge “Trees on privately-owned land provide benefits for the entire community,” Albro points out. “They help filter and cool the air, they absorb stormwater, and they help save on energy costs for homes nearby. So even though you may be using your own yard to plant the trees, the benefit to the community is far greater.” The tree communities with the greatest need are rural regions where forestland decreased by 300,000 acres and live trees decreased by 1 million from 2013 to 2018, according to the Cleveland Tree Plan 2020 Tree Canopy Progress Report produced by the Cleveland Tree Coalition. In Cleveland, the tree canopy declined by 5 percent from 2011 to 2017. “Our arborists, scientists, community foresters, horticulturists and educators work onsite at the Holden Arboretum and Cleveland Botanical Garden, and in our community to grow and care for trees each year,” Koski says. “But we can only plant so many.” To truly make a difference, People for Trees recruits individuals and families throughout the region to plant and care for a tree in their yards, places of business or neighborhoods. “We are inviting every member of our community to take notice of the trees around us,” Koski says.

12   FORESTS & GARDENS

People for Trees is designed to grow an appreciation for trees, along with direction and education to guide individuals so they can succeed in caring for trees. Koski says, “We have been dedicated to tree care and preservation for nearly 100 years, and we have nationally and internationally recognized research programs in tree science and conservation, so this is an opportunity to share our deep knowledge and expertise outwardly to ensure the long-term preservation of our forests and tree canopies.”

Arbor Day, Every Day Arbor Day is an ideal time to kick off the planting season and celebrate all that trees give us. Pledge to plant a tree through the People for Trees campaign at holdenfg.org/people-for-trees, or you can donate to have a tree planted on your behalf. HF&G will provide the resources you need to be successful. “We’ll be giving saplings away at both campuses, along with information about tree species,” Albro says, relating that the website includes how-to-plant videos, maintenance advice, and tree care insights on topics including pruning, mulching and watering. “We also offer a tree species selection guide that allows you to pick a good tree based on the site characteristics and what you are looking for,” Albro says. “For example, do you want a flowering tree — or do you like fall color, or want a tree that will feed the birds.” People for Trees pledgees also receive a monthly newsletter, Albro adds. “We’re trying to spread the word about trees and encourage people to act in their own spheres — homes, churches, schools and places where they recreate.” While there will be a special push to promote People for Trees during Arbor Day, Koski points out, “We will continue to celebrate trees 365 days a year.”

Rooted


in Community The HF&G master planning process engages neighborhoods and invites diverse voices to shape the future. By Kristen Hampshire Inspiring connections and collaborating with the communities we serve is a focus for Holden Forests & Gardens (HF&G) as we drive forward with our 2022-2024 strategic plan, complete with a new mission, vision and five-year institutional goals. “The master plan is the physical manifestation of the institution’s mission, vision and strategic plan and how we will serve the community at both of our campuses in the years to come,” says Jill Koski, HF&G president and CEO. The plan advances the idea of a public garden and arboretum as world-class demonstration sites where people can engage and connect with nature,” adds Koski. HF&G engaged a team led by Nelson Byrd Woltz Landscape Architects and GWWO Architects to create a landscape plan that will guide our evolution. HF&G also enlisted ThirdSpace Action Lab, a grassroots Cleveland-based research, strategy and design cooperative that is centered on inclusion and creative solutions to realize racial equity. ThirdSpace helped develop an external steering committee and walked us through the process of envisioning how its campuses can be meaningful to all communities it serves. The external stakeholder piece has been crucial and involved multiple workshops and listening sessions.

Also involved in the planning process are partners James Lima Planning + Development, ETM Associations and OHM Advisors. Beyond physical structures, “it’s about raising up the rich natural assets we have,” and at the botanical garden “we are building around this centerpiece of the Erie Gorge and raising that up along with the natural landscape,” Koski says. “The botanical garden and arboretum are living museums and we will highlight this from the moment you enter either campus,” she notes, emphasizing that HF&G also hopes to introduce its story to those in the region who have never happened upon either campus. Ultimately, the master plan will outline strategies to achieve our forward-thinking goals: •Presence: building an engaged, connected, collaborative community presence •Experience: delivering a visitor experience that inspires wonder, and highlights the beauty and value of trees and plants •Stewardship: catalyzing action and model solutions for environmental stewardship •Equity: increasing diversity, equity, accessibility and inclusiveness at every level •Financial responsibility: achieving sustainable financial results that enable growth and ongoing capital investment “We are highlighting the role and importance of public gardens at each of our destinations, and we want our campuses to be integral parts of the communities and neighborhoods that we serve,” Koski says. This year, we will move into “testing phase” and a public feasibility process to gauge philanthropic support and try out ideas with a broader community. “We want the community to have a voice because, as a nonprofit, we are of service to the community through trees, plants and nature,” Koski says.

Conservation in a Changing World How to help oak trees, soil fungi and international collaborations By Claudia Bashian-Victoroff, M.S., Research Specialist

A

s an accredited museum, one aspect of Holden Forests & Gardens’ essential mission is to collect and preserve plant species for conservation, educational and scientific exploration.

Today, the conservation and study of plant species is of growing concern due to global change and the accelerated extinction of plant species. Although conserving plants in their natural habitat is the best approach, often plants need to be housed in botanical gardens and arboreta, to preserve the species and provide an insurance policy against extinction in the wild. But how to best conserve plant species in gardens so that they thrive is often an open question. If “the first rule of intelligent tinkering is to save all the pieces” as the biologist Paul Ehrlich once said, then the question becomes what essential pieces are needed to preserve plant species in collections such as those at Holden. Plants interact with many other organisms needed for their survival, such as pollinators. One underappreciated group essential for plant survival and growth are the mycorrhizal fungi that colonize plant roots and help plants acquire nutrients and resist disease. Mycorrhizal fungi live in soil and form mutually beneficial relationships with 90% of all plant species, including tree species such as the oaks (genus Quercus). Oaks as a group are of international conservation concern. Based on work from Morton Arboretum, 41% of all oak species are of conservation concern and many current efforts are underway to preserve oak species throughout the world. But the success of oaks within 20   FORESTS & GARDENS

collections, and even within efforts to restore species to their native environment, may depend on having the right mycorrhizal fungi colonizing the root system. Our understanding of oak and mycorrhizal fungi relationships is still poor and more research in this area is needed. In July of 2021, Holden research graduate student Claudia BashianVictoroff began an international collaboration to study oak trees and their mycorrhizal partners with researchers in the United States and Armenia. This collaboration stemmed from an earlier effort in October 2020 by Claudia and other mycologists of Armenian descent to found the International Congress of Armenian Mycologists (ICAM). The mission of the group is to build science capacity in Armenia by:

1 collaborating with the nation’s already successful scientists through shared research projects

2 providing scientific mentorship to Armenian youth and 3 gathering biological data that can be used in the protection of land and life

Work began by reaching out to fungal and plant biologists at Armenian institutions, including the scientists at the Yerevan Botanical Garden, located in Armenia’s capital city. After months of video conferencing and planning with Armenian scientists, Claudia and other researchers traveled to Armenia to formalize the


Artavan, Vayots’ Dzor province, Armenia. To travel towards southern Armenia the group followed the path of the ancient silk road and stopped at a structure used by travelers up until 1400 C.E. This structure overlooked the Vayots’ Dzor province (shown here), which is relatively dry and extremely mountainous. While the whole country of Armenia is about a quarter the square-mileage of Ohio, the mountainous landscape makes for extremely variable climates between the northern and southern parts of the country.

newfound relationships and collect biological samples for research. The scientific expedition to Armenia included botanists, who identified the native plants of Armenia; mycologists, who collected and identified mushrooms and other fungi; lichenologists, who collected lichens of off trees, branches, and rocks; plant pathologists, who could spot and identify plant diseases; a paleobotanist, who knew the geological history of Armenia like the back of his hand, and two fungal ecologists (including Claudia), who collected soil and roots to study the connections between plants and soil fungi. Most days included long hikes through mountainous forests, past ancient monasteries and monuments, followed by large traditional Armenian dinners usually including lavash (Armenian flatbread), tomatoes, eggplants, and kabab. One of the best aspects of the trip was working in the Yerevan Botanical Garden. The scientists at the garden were generous with their time and knowledge, and Claudia was able to collect root fragments from species of oak trees represented in their collections. By collecting roots, we will be able to identify the species of fungi growing in the soil. Collected roots included oak species from in the botanical garden and in natural areas around the country. This collection is paired with root fragments from oak trees in the collections here at Holden. One aim of the project is to

compare the soil fungi living on oak roots in Ohio and Armenia using fungal DNA extracted from the collected roots. Another aim is to begin an ongoing, international collaboration between scientists at the Holden Arboretum and at the Yerevan Botanical Garden. Claudia is now collaborating with Sona Galstyan, a botanist at Yerevan Botanical Garden to identify the fungal species on the roots that were collected from both gardens. Since the collection trip, the focus has turned to collaborating with our Armenian colleagues to host online workshops in Armenian, and to collaborate on grant applications to further the research. You can learn more about the trip through Holden’s recent blog post on holdenfg.org.

Planting the Seeds at Summer Camp Camp experiences promote social development, sense of place and environmental stewardship. By Jen Graham, Public Programs Coordinator

From a social perspective, summer camps present an excellent opportunity for children to practice making new friends and developing relationships.

ummer is a season of plenty. Life proliferates under logs and inside tree cavities. Prairies and gardens burst into color, and native pollinators enjoy a buffet of sweet nectars. The low rumble of bullfrogs ripples through murky ponds; the cheerful whistle of migratory birds hangs on the wind; and the rustling of chipmunks and garter snakes in the leaf litter causes us to pause and listen. With all its sensory wonders, summer is the perfect season for children to explore, and there is no better way for young nature lovers to get to know their environment than through a summer camp experience.

Although schoolbooks will be returned to the library and binders will be stored away, children never stop learning. For over a century, summer camps have invited children to connect to a world outside their familiar homes and schools and “build character” through challenging activities and fun outdoor games. Campers often return home feeling refreshed and confident, brimming with tales of wild adventure. However, the many benefits of these camps were largely anecdotal, passed down through smiling faces in photographs and nostalgic stories. It wasn’t until 2005, when the American Camp Association (ACA) conducted a study of summer camps across the United States, that significant statistical evidence arose to support summer camps as spaces of social and intellectual development. Indeed, the ACA study found that children who participated in just one session of summer camp saw substantial growth in a variety of areas, including self-esteem, independence, social skills, risk assessment, decision making, sense of place and personal

friends, children grow more comfortable taking risks and take pride in their achievements, leaving with more confidence in themselves and their social networks.

values. Notably, this growth was often reported to persist beyond camp and into children’s daily lives. This data corroborates the long-held understanding that summer camps provide unique learning experiences, tailored to support social-emotional growth. Under the guidance of dedicated camp counselors in beautiful natural settings, campers develop important tools to help them succeed, even after they return to their regular routines. From a social perspective, summer camps present an excellent opportunity for children to practice making new friends and developing relationships. The goofy games, silly songs and creative crafts of camp foster an environment where children can feel safe to experiment, relax, open up and be themselves. When everyone is learning a new skill together, campers are encouraged to work as a team, manage disagreements, share successes and persist through disappointments. With the care and support of respected camp counselors and new

Additionally, because most summer camps offer a unique outdoor experience with counselors serving as stewardship role models, children also show significant growth in their ability to appreciate, connect to and care for the environment. Free from the constant demands of technology and screens, campers begin to exercise their imaginations and pursue new interests. Their senses activate their learning, making the lessons deep and impactful. They absorb facts about nature, not because they must, but because they are hungry to learn more. Fresh air and sunshine promote calm and focus. Exploring the outdoors through structured and unstructured play is essential to developing a sense of wonder and comfort in nature. At Holden Forests & Gardens, stewardship is a top priority in our camp experiences. Not only will campers forge friendships with each other, they’ll also forge friendships with box turtles and pine needles, with roly-polies and milkweed. Indeed, summer camps are an invitation for children to emerge and engage

The Forest & Garden Continuum How we can conne ct landscap e s on campus and in hear ts and minds . By Caroline Tait, Vice President, Horticulture & Collections

O

n walking the grounds at Holden Arboretum one is amazed by the range of plants in the highly designed cultivated gardens. HF&G’s Living Collection is displayed in representation of a green living museum. However, we host and care for many additional plants of native and natural occurrence throughout the Arboretum Core. These are visible in a series of forested areas, which connect the cultivated gardens. In a much broader scale one can recognize this in our residential landscapes, too — gardens connected by wild, often lightly forested, spaces.

It became apparent that we have an opportunity to offer HF&G guests a close-up introduction to the options available to manage this type of space. If an interest is piqued, then the Working Woods program can teach larger scale action in woodlands for aesthetic and economic benefits. Ensuring that any program within a department utilizes the best of knowledge from across HF&G teams means our guests receive the best of current management understanding, and our horticulture teams can implement our scientist’s research. Science and Horticulture are points on a continuum of understanding the land.

Public Gardens as Sentinels of Invasive Plants By Tom Arbour, Curator of Living Collections

I stepped into the role of Curator of Living Collections last September following a career focused on natives, invasives and land management across Ohio, and am excited to curate our Living Collection of more than 20,000 accessioned plants and trees. My key responsibility is to ensure the Living Collection reflects HF&G’s mission to, ultimately, inspire action for healthy communities. As I begin developing collections plans for each of the individual genera — Quercus, Malus, Rhododendron etc., it is critically important that plants chosen for ex-situ conservation, i.e. conserved on campus outside of their native range, stay in our gardens and do not spread into our natural areas or the communities we serve. HF&G has taken a lead in recognizing invasive plant species across cultivated and natural landscapes. Norway maple, Japanese barberry, winter creeper and Callery pear are among the dozens of plant taxa that have been removed from our Living Collection

24   FORESTS & GARDENS

although it can take longer for the commercial industry to take these steps. In recent years, Horticulture & Collections staff have collaborated with other public gardens to help sound the alarm about plants that are escaping cultivation locally. This network, known as Public Gardens as Sentinels against Invasive Plants, provides both monitoring protocols and an online database for public gardens to submit information about these plants that ‘may “go wild.” Plants are categorized as‘‘watchlist,’ ‘potentially ‘invasive’ and ‘invasive’ based on a number of criteria, including information collected by Holden’s staff about the number of plants that have escaped cultivation and how far they have spread from the parent plant. The PGSIP guidance will be implemented throughout the Arboretum Core across gardens and connecting forest fragments.


The Holden Arboretum has a wide variety of greenspaces, creating a continuum from highly designed gardens in the core all the way to our conserved natural areas. The areas on opposite sides of the spectrum are managed very differently and by completely different departments, but sometimes our work overlaps: In the natural areas in the core, our horticulture and conservation disciplines collide, allowing the space to act as a bridge between gardens and natural areas.

Core Natural Areas Recent History By Ann Rzepka, Director of Horticulture

One of the many reasons HF&G is unique is that one membership affords a matrix of high quality natural and cultivated landscape experiences across multiple campuses. These experiences are the product of time, geologic conditions, evolutionary biology and the foresight of our founders to preserve them. They are held to integrity through planned land management conducted by our boots-on-the ground team of conservationists, horticulturists and scientists in their respective departments. Traditionally, Science & Conservation department efforts at the Arboretum focused on the natural lands that comprise over 3,000 acres of the Arboretum’s property in Lake and Geauga counties. These natural areas preserve the botanical heritage of Northeast Ohio and provide scientists an opportunity to explore and understand the attributes that contribute to the richness and diversity of these high-quality natural areas and, thus, inform management strategies. The Horticulture & Collections department at the Arboretum has concentrated efforts toward the care and maintenance of an expanding Living Collection, cultivated for conservation, education and the sheer beauty within the 232-acre core of the Arboretum. Contained by the deer fence, the Arboretum Core comprises a gradient of landscapes ranging from highly designed and curated gardens to managed meadows and forest fragments.

In 2020, the departments convened to explore how these spaces could be leveraged in support of the HF&G mission. Staff identified the fragmented forests within the core that were highly visible to guests and began to inventory the species diversity within the existing plant communities. A little over 30 acres of fragmented forests were identified in these initial assessments ranging in size from a half acre to 7 acres — now referred to as the Core Natural Areas. This is significant within the context of the greater forested land in Ohio because small, fragmented forests represent over 1 million acres of the forested land within the state of Ohio, and 85% of these forests are privately owned. (USDA, Ohio Forests Resource Bulletin, NRS -118) Initial plant inventories revealed an array of invasive exotic woody species, including Frangula alnus (glossy buckthorn), Rosa multiflora (multiflora rose) and Ampelopsis glandulosa var. brevipedunculata (porcelain berry). These invasive species quickly alter the area they invade — changing the availability of water, light and nutrients, and forming dense monocultures, which reduce native plant regeneration and diminish habitat quality (Pimentel et al. 2005). These findings were also significant within the broader context of Ohio’s forested land as the state has a higher percentage of plots with one or more invasive plant species (96%) than surrounding states. (Widmann et al. 2014)

With in-house knowledge and skills we are uniquely equi85pped to marry our horticulture and conservation practices to better understand the dynamics and to implement management strategies within these fragmented forests. These management strategies will help improve the overall aesthetic experience in the Arboretum Core, creating visually appealing transitions between highly cultivated gardens and natural lands. They will also have the potential to demonstrate how private landowners can improve their own forests, thus impacting forest health broadly throughout our communities.

A total of 85% (6,778,000 acres) of forest land in Ohio is privately-owned. The other 15% is owned by governments or in public holding. Most of that privately-owned forest is in the hands of individuals or families, and small, privately-owned woodlands less than 10 acres in size account for approximately 1.15 million acres in Ohio. The takeaway? Private landowners hold most of our state’s wooded land and thus most forest stewardship rests in their hands. Increasingly, Ohio forests are being fragmented and owned in smaller and smaller units. Research has shown that separated and discontinuous forest units reduce animal and plant diversity and make areas more vulnerable to environmental threats. This makes small woodland owners more important than ever for the future of Ohio’s woodlands.

Economical & Sustainable Clean-up By Rob Maganja, Horticulturist

On the ground we’ve encountered less-than-ideal weather, pandemic challenges and have had to coax the woodchipper into action. These hurdles serve to grow collaborative relationships, and over more than a year of action we’re really getting into a groove. We’re currently working on the Core Natural Area due east of the 2-acre Butterfly Garden. Especially in October and early November, when the temperatures were a little warmer, the effort to drag brush hundreds of feet and even up elevated and sometimes muddy inclines was impressive. Probably the most delicate aspect of the operation is the disposal strategy for all the waste material we generate. We all agree that the most important disposal strategy is one where we’re spreading the invasives as little as possible. While there are legitimate options to leave or remove the waste material for disposal elsewhere, for now we’re leaving the waste material on-site. Work is ongoing in that Core Natural Area, the most inundated of the sites. Once that is complete, we’ll have a nice template for how to do every future site in as economical and sustainable of a way as possible.

We will share this with our guests and community homeowners to consider for their own backyard fragmented forest habitat. Based on joint experience, we need about two years to manage invasives and their seedbanks before restoration planting can occur. At that point, we aim to introduce many native plants that can hold their own or repress aggressive invasives. Agroforestry elements will start to creep into the design palette; both native and non-aggressive exotic edible plants will be favored; maybe even hearken to our rural surroundings and explore how livestock and perennial plantings can go hand-in-hand; plant windbreaks to create microclimates for plants more suited for a slightly-warmer growing zone; include nearly-forgotten practices like coppicing and pollarding; use plants that can adapt to our changing climate. The list of possibilities goes on. In short, the Core Natural Areas act as bridges between our cultivated garden and high-quality forest communities to demonstrate an ecosystem continuum on which private lands throughout the state can be modeled on.

Baltimore Oriole Icterus galbula

altimore orioles have adapted to human settlement. The vibrant orange color of the males makes them easy to spot in open woodlands like parks, orchards and backyards. Their clear, flute-like whistled songs are commonly heard high in leafy deciduous trees.

Baltimore orioles are acrobatic feeders hanging upside down on tree branches searching for insects, nectar and fruit. They can also snatch flying insects in midair. Their diet consists mainly of invertebrates, including beetles, grasshoppers, moths, flies, spiders and snails. Unlike most birds, they even eat hairy pest caterpillars. They forage on a variety of berries and sometimes cultivated fruit. Unlike other fruit-eating birds, Baltimore orioles prefer only ripe, dark-colored fruit. Both males and females frequently visit bird feeders supplied with fruit (orange halves), jelly (grape) or nectar (sugar-water) in spring, late summer and early fall.

SIZE: 6.7-8 inches WINGSPAN: 9-11.5 inches DESCRIPTION: Adult males bright orange breast, solid-black head, and black with one white bar on their black wings. Females and immature males dull yelloworange breast and rump, faint black-gray head and back; two white wing bars.

During the courtship in spring, males hop around the females, bowing forward and spreading their wings. The female responds by fanning her tail, fluttering, lowering her wings and making a chattering call. Once females choose the males and nesting sites, male Baltimore orioles defend small areas only around their nests. Baltimore orioles prefer Elm trees but build their nest in other trees such as cottonwoods and maples. Sock-like hanging nests are constructed mainly by the female in four to eight days. Pouches are firmly attached to the fork of branches 25 to 30 feet high. Nests are three to six inches deep and are woven out of slender plant fibers, including barks, grapevine and grass. The nests can even include synthetic yarn and string. Nests are lined with fine grass, plant down and animal hair. Females will often recycle plant fibers from an old nest to build a new one. Females lay four to five pale gray to white or bluish-white eggs. Eggs are speckled with black and bluish-purple markings, mostly at larger ends. Females incubate the eggs from 12 to 14 days. Young leave the

nest 12 to 14 days after hatching. Both parents feed the nestlings. Baltimore orioles are widespread and common. However, according to the North American Breeding Bird Survey, their populations are declining. Canada has experienced the most significant loss, with 3% per year since 1966. Baltimore orioles, like other birds, are vulnerable to deforestation and habitat loss. Habitat loss in both breeding and wintering grounds is one of the top reasons for bird population decline.

RANGE: Breeding Nearctic, Canadian Prairies and eastern Montana in the northwest; eastward through southern Ontario, south through the eastern United States to central Mississippi and Alabama and northern Georgia. Winters predominantly in Central America and northern South America VOICE CALL: Both male and female rapid chatter Song: slow, loud, flute-like two notes repeated two to seven times BEST LOCATION TO VIEW: Arboretum: Display Garden Garden: Topiary and Hershey Children’s Garden

Picture the windswept grasses on the dunes of Lake Erie; the bogs sweetened by blueberry bushes in summer. These are but few examples of the nearly 1,800 vascular plants native to the state of Ohio.1

plants. Here you can find great white trillium (Trillium grandiflorum) and Dutchman’s breeches (Dicentra cucullaria) rescued from land slated for development in Medina. You will find large tuliptrees (Liriodendron tulipifera) estimated to be over 100 years old and a grove of sassafras (Sassafras albidum) that add a sorbet swirl to the fall canopy.3

WHAT IS A NATIVE PLANT? We interpret native plants as the plants that grew here free from human intervention. They are plants believed to have made their homes here before our European predecessors arrived and brought plants from other places.

“There is a lot of potential to build more intention in this space; to showcase native plants in a natural yet cultivated way,” Horticulturist Stefanie Verish shares. “The soils are sandy and alkaline. This means opportunity to provide habitat for Lake Plain species and to experiment with using native shrubs to combat erosion. It’s about choosing the right plants for our situation.”

Over time, people influence the land. Non-native plants are introduced, purposefully or accidentally. The geographic ranges of native plants are extended or truncated. All this to say, our definition is not so black and white. And although we celebrate Ohio Native Plant Month (ONPM), limiting the pretext of native to state boundaries can be a gray area. “Take a plant like bottlebrush buckeye,” suggests Nancy Linz, president of OHPM and founder of National Native Plant Month. “Bottlebrush buckeye is not native to the state of Ohio — its range is more southern. But you cannot look at a bottlebrush in my Cincinnati garden covered in pollinators in July and tell me that it is not a great plant.” “The important thing is that people decide for themselves how to define a native plant,” says Linz. And that may be the best way to celebrate OHPM; to invite conversation on the topic and allow for many shades of interpretation. For some, native may be defined by state boundaries. For others the definition may include all eastern North American flora. For all, there is a plethora of native trees, shrubs, forbs, ferns and grasses to admire and help flourish.

At Holden Arboretum, the iconic Myrtle S. Holden Wildflower Garden has been a haven for native plants, common and rare, since 1968. Initially proposed to offer guests an opportunity to get familiar with the flora of Pierson Creek Valley, this 5-acre garden has evolved into over a dozen thoughtfully crafted habitats, including woodland, floodplain, bogs, prairies and rockeries. Today, over 300 varieties of plants from 35 Ohio counties call the Wildflower Garden home. HF&G Horticulture & Collections staff obtain permission and appropriate permits from local, state and/or federal entities in order to collect these propagules. HF&G is supported in this custodial role by the Center for Plant Conservation. “What’s often overlooked is the potential this garden has to act as a gene repository for rare and endangered plants,” says Ann Rzepka, director of Arboretum Horticulture. This garden currently holds populations of 61, or approximately 10%, of the 619 vascular

NATIVE PLANTS AT HF&G If a wildflower is a plant growing in its natural habitat by its own volition, then the concept of a wildflower garden may be an oxymoron. As it were, this may be true. But the value of a wildflower garden supersedes the parsing out of phrases. Over the years, the institutions that make up Holden Forests & Gardens — the Cleveland Botanical Garden and Holden Arboretum — have contributed to the protection and promotion of Ohio native flora through wildflower gardens. At the Botanical Garden, this work is exemplified in the Woodland Garden. This corridor of woodland mingles native with introduced

plants listed on ODNR’s Rare Native Ohio Plants 2020-21 Status List.4 “By creating habitats for these plants, we display and conserve them as a ‘‘back-up’ for wild populations.” Some of the plants in the Wildflower Garden were collected from plant species now extirpated from the state. With continued care and relationships with landowners, we can propagate and reintroduce these plants to their natural habitats.

NATIVE PLANTS IN YOUR GARDEN In 2021, HF&G became one of four inaugural Learning Centers for OHPM, together with Cincinnati Zoo & Botanical Gardens, Dawes Arboretum and Metroparks Toledo. The primary goals are to share knowledge to better grow and protect native plants, collaborate to showcase and promote native plants for residential and landscape gardeners and advocate for those potentially overlooked native plants. HF&G is currently supporting OHPM’s bipartisan Senate resolution to designate April 2022 as National Native Plant Month. You may be inspired to seek out native plants for your own garden, a move that pays homage to the land and benefits local ecosystems. To do so with success, consider your garden’s setting. How much sun does an area get? Are there deer in your neighborhood? Is your soil thick and sticky clay, quick-draining and gritty sand, smooth and soapy loam or somewhere in between? There are native plants for every situation. A good place to procure them is at Holden’s Plant Sale, which occurs twice a year in spring and fall. Many local nurseries also offer native plant selections. Inquire at retail stores or talk to your landscaper about their wholesale suppliers. Please refrain from digging plants from natural areas. To find out more about Ohio native plants visit ohionativeplantmonth.org. The goal of Ohio Native Plant Month is to promote the value of native plants and to offer opportunities for all to relish in the beauty of native plants; what was here and what remains.
