There are rites of spring. This year, meteorological spring (based on annual temperature cycles) began March 1. The Vernal Equinox (based on the position of the earth to the sun) happens March 19. By the time April comes, spring is in the air.

Yet the Arboretum has been preparing for spring all winter. What does it take to get gardens ready for spring? In February, horticulture staff were planting seeds, placing seed orders, pruning, containing invasive plants, preparing mechanical equipment and of course, plowing snow. In March, pruning and garden cleanup—removing winter mulch, conducting soil tests, preparing soil when the ground warms and dries. In April, the garden crews, including our dedicated volunteers, plant early blooming pansies, violas, snapdragons and kale. With the crocus, squill, snow drops and more planted last fall, in all 10,000 bulbs are blooming! In May, spring is in spectacular bloom: 30,000 tulips (from bulbs planted last fall), fragrant lilacs and legendary crabapple blossoms.

So, take a break from your hectic pace. Enjoy the beauty of the gardens. Explore nature and the outdoors. Delight in the events and whimsy of the Savage Gardens exhibit. See you at the Arboretum.

Woodland Azalea Garden & Waterfall

The First in a Series on Arboretum Natural Areas with Water Features Susie Eaton Hopper Public Relations Specialist

Mandarin Lights in Woodland Azalea Garden Photo by Ken Evans

The recently refurbished Packard Woodland Azalea Garden and waterfall, just steps off Three-Mile Drive, is one of the most serene and natural areas at the Arboretum.

Tucked on the edge of the Big Woods and bordering the Hosta Glade, this woodland retreat invites visitors to relax and unwind. Its cascading waterfall, surrounded

by Lake Superior taconite boulders, splashes into the koi-filled reflecting pool, creating a soundtrack for the gorgeous show of winter-hardy Northern Lights Azaleas.

The garden was refurbished with generous support from long-time Arboretum volunteer Betsy Packard. Improvements include expanding the waterfall, repairing the pond base and adding paths. Originally constructed in 1984 as a showpiece for the spring-blooming azaleas, one of the premiere Arboretum-developed plant introductions, the garden is cooled by the shade of the nearby Sugar Maple collection.

Over the years, the trees had grown, making it harder for the sun-hungry azaleas to establish and thrive. As part of the redesign, more light was coaxed into the garden and colorful azaleas, herbaceous perennials and native plants were installed to create a magical woodland tableau.

Visitors now experience a stunning, colorful Northern Lights Azalea show in April and May, complimented by redbuds, magnolias and daffodils. Lush summer greenery include ferns, Astilbe, hosta and sedges. Pond-side plants include Petasites, Iris and Ligularia. It is the perfect spot to sit, reflect and recharge the senses.

WOODLAND AZALEA GARDEN BY THE NUMBERS: • Garden size: .05acres • Pool size: 1700 sq. ft.

• Pool depth: 4 ft.

• Donor benches: 6

• Koi in pool: Too many to count!

Dandelions – Friend to Pollinators Matt Schuth Naturalist Pictured is a packet of dandelion seeds distributed by the Northrup King Company in 1903. The seeds sold then for 10 cents. The packet, from my collection, informs the prospective buyer that the plant has "improved thick leaves," and is "excellent for home and market gardens." It’s hard to believe that since those days, millions of dollars have been spent in vain trying to eradicate the dandelion.

Dandelions are very high in nectar and have strong ultraviolet reflection, attracting nearly one hundred different pollinating insect species, including honey bees. They have one of the longest flowering seasons of any plant.

In Minnesota, it is not unusual to see dandelions starting in March, and thriving into November. Dandelion root systems can penetrate the ground to a depth of a foot or more, and can reproduce from roots and root fragments. They can also reproduce asexually and through self-pollination.

Dandelions are a composite flower with about two hundred seeds on every seed head. When the flowers turn to seed, the stem grows higher in order to catch the wind which disperses

the seeds further. When they are mowed, some plants become shorter to survive. That’s evolution in action.

Dandelions produce more Vitamin A than carrots and more potassium than bananas. Outdoorsman Euell Gibbons, a proponent of natural diets during the ‘60s and ‘70s, said the roasted root was the best coffee substitute in America. Recent studies have shown that an extract from the plant increased red blood cells, and in high doses, normalized white blood cells. The root has been shown to stimulate weight loss, and has antioxidant and diuretic features.

An old myth said that if children touched or ate the plant, they would wet the bed … so it was not a potherb but a “potty” herb.

It is ironic that the dandelion, a flower that is the symbol of love, has turned into such an object of derision to so many. Visit the weed garden at the Arboretum to view dandelions up close.

Growing Support of Plant Conservation and Research With the Arboretum’s heritage rooted in plants and horticulture, the Arboretum Campaign support of plant conservation and horticulture research will sustain its legacy. Generous financial support is aiding efforts to continue work in three critical areas: cold-hardy plant research and introductions, preservation of native and endangered plant species, and protection of natural biodiversity.

GALA GARDEN PARTY: BEE INSPIRED Thursday, June 23 Save the date for the Arboretum’s premier 2016 garden party to kick off summer!

The buzz-worthy evening begins at 5:30 p.m. with an outdoor reception.

Enjoy music, dinner el fresco featuring locally-sourced cuisine, plus an auction, and the annual Fund-A-Need. The Gala Garden Party will be hosted by the Minnesota Landscape Arboretum Foundation Board of Trustees. Your generous support will ensure the future of the Arboretum.

Remember to take in the Arboretum’s summer in bloom – and summer exhibits “Savage Gardens” and “Big Bugs” in the gardens.

Thank you to the following Gala Garden Party sponsors for their generosity: Wells Fargo, UnitedHealth Group, Bailey Nurseries, Cargill, Loeffler Construction & Consulting and Solution Blue.

In 2014, the Oregon Woody Plants Research Station, located in the Willamette Valley, was transferred to the University of Minnesota by a Minnesota-based nonprofit established by the late Harold Pellett, Ph.D., a retired University professor who introduced some 25 cold-hardy shrub and tree varieties. In 2015, the Harold and Shelby Pellett family established a horticultural research endowment to ensure further woody plants research.

Generous donor support also funded a horticultural curator for woody plants to operate the Oregon research station and evaluate new woody plants for their potential value to the nursery industry and homeowners, and to focus Arboretum woody plants hybridizing and cold-hardy testing.

In addition, State of Minnesota funding from the ENRTF (Environment and Natural Resources Trust Fund) helps support native orchid conservation and research and a curator for native plants and endangered species. In partnership with the Center for Plant Conservation, the Arboretum plays a pivotal regional role preserving rare and endangered plants, such as Minnesota's endemic dwarf trout lily.

While more remains to be done, Arboretum Campaign support has fostered plant conservation and horticultural research to benefit the community and world.

You make a difference! To support the Arboretum Campaign with your gift, donate at the Oswald Visitor Center; go online at: arbcampaign.org; call the Development office at 612-301-1263; or mail a gift to: Arboretum Campaign, 3675 Arboretum Dr., Chaska, MN 55318.

Getting to the Root of Water Conservation:

IDEAL SUMMER FOR AAS GARDEN

Water-Wise Watering Practices starting in Your Own Back Yard!

Leslie Yetka Horticulture Education Manager

We all know that plants need water to be healthy and grow vigorously. Plants with just the right amount produce more flowers, more vegetables and fruit, are more disease resistant, and make for less room for weeds. However, the water that comes from our hose is often the same as the treated drinking water we use in our house. As we move into the planting season, paying careful attention to how much water we use for our plants is important to ensuring we also have a plentiful supply of clean, fresh drinking water for our communities.

FOLLOW THESE WISE WATERING TIPS: • Pay attention to the weather: use a rain gage, weather station data or the news to monitor how much rain your plants are getting.

• Feel the soil: if it’s moist, no water is needed. If it’s dry, then it might be time to add water.

• Water at the base of the plant, water deeply, and only when needed.

Drip irrigation will ensure that only soil and roots get wet, and less water evaporates into the air.

• I f using irrigation on your lawn, apply early in the morning to reduce evaporation, and on sunny days so leaves dry quickly. A minimum of a quarter-inch of water a week is all that is needed for lawns to stay healthy.

• Newly planted trees need regular water and even mature trees need water during periods of drought. Add water if you observe wilting or when soil is dry...do not wait for severe wilt, leaf browning or branch dieback, as damage has been done at that point. Happy watering!

Learn more about water conservation and wise watering practices at the upcoming Earth Day workshop at the Arboretum on Friday, April 22. Details and registration at: arboretum.umn.edu/2016EarthDayLearning.aspx Read more: "Month-By-Month Gardening Minnesota & Wisconsin" Before you begin your spring planting, pick up this definitive monthly manual of "when" and "how" to care for your garden.

A near-perfect growing season last summer was the ideal setting for trial garden seed varieties for flowering and vegetable plants. As a test garden for All America Selections (AAS), the Francis DeVos Home Demonstration Garden becomes an “idea lab” for visitors and home gardeners. Arboretum landscape gardener Ted Pew and his crew of staff and volunteers track and evaluate color, flowering length and disease resistance, as well as flavor, texture and taste and season-long harvest. Compact form for square-foot gardens, containers or window boxes; bright landscape effect (color and numbers of flowers per plant) and staking were considered.
