Amidst spring color, unfurling ferns offer different kind of beauty

May 17, 2013 under CANR News, Cooperative Extension

The May landscape at Winterthur is reminiscent of a child’s finger painting. Here, a bright splash of red and coral from azaleas. There, luminescent lavender on lilacs and phlox. Throw in a cheerful dab of gold from Rhododendron luteumand a dash of pastel pinks from dogwoods, too.

Amidst this riot of color, Linda Eirhart was a woman on a mission one recent morning. Oblivious to the rainbow hues around her, Eirhart drove a golf cart down Winterthur’s pathways, searching for new ferns unfurling their fronds.

fernsAt first glance, one might wonder why Eirhart, Winterthur’s assistant director of horticulture, would bother chasing down ferns. Unlike spring blooms, there’s no immediate wow factor. All the ferns are pretty small now, even the ones that will ultimately reach two to three feet high. It’s easy to overlook a tiny fern growing just a few inches from the ground. However, if you crouch down for a closer look, you’ll enjoy a sight as spectacular in its own right as the brash blooms of spring.

Take, for example, emerging hay-scented ferns. These clusters of chartreuse apostrophes twirling in the breeze resemble some bizarre plant from a Dr. Seuss book. Another fern that looks other-worldly now is cinnamon fern. Its fronds are tightly wound in a circular clump, encased in white hairs.

“Ferns are a real favorite of mine,” says Eirhart. “They’re fascinating as they emerge. Then, once they unfurl and mature, they provide interesting foliage and texture throughout the growing season.”

Not to mention the way they seem to lower the thermometer once the steamy hot days of summer arrive.

“Ferns create a cooling, peaceful effect in a landscape,” says Sue Barton, UD Cooperative Extension specialist for ornamental horticulture. “The March Bank at Winterthur is a great example of this cooling effect.”

The March Bank’s main claim to fame is its spring color. In the early 1900s, H.F. du Pont began planting thousands of bulbs on a hillside near his home that he dubbed the March Bank. He mixed ostrich, cinnamon and New York ferns amidst the bulbs for season-long interest. Du Pont would go on to inherit Winterthur from his father and, a short time after that, establish the property as a museum.

Come summer, the ferns that du Pont planted will create a thick, lush carpet of green in a range of colors, shapes and sizes. There’s the almost chartreuse green of the New York fern, which contrasts with the multi-colored hues of the cinnamon fern. The cinnamon fern has two types of fronds – large green sterile ones and smaller fertile ones that start out bright green and soon turn a cinnamon color. Some of the taller varieties include the ostrich fern, which can reach 5 feet and the New York fern, which tops out at 2 feet in ideal conditions.

“I love ferns,” says Chris Strand, director of garden and estate at Winterthur. “Growing up in Colorado, ferns weren’t common. We didn’t get 39 inches of rain annually like Delaware gets, nor did we have the right soil conditions for ferns. When I moved East, I was amazed by all the ferns here. It’s beautiful now, when the bluebells are fading on the March Bank and the emerging ferns are coming in. All the fronds waving in the breeze look like waves on the ocean.”

Delaware has 67 native ferns, according to Bill McAvoy, a botanist with the state Department of Natural Resources and Environmental Control. Winterthur doesn’t have all those ferns but it’s certainly got a lot. In addition to the March Bank, there are good collections of ferns in the children’s garden, Enchanted Woods; as well as in the Pinetum. And what was once a small fern collection at the Visitor’s Center has been given a big boost recently. Over the past five years, Eirhart, her staff, and volunteers have added thousands of new ferns to this area.

The University of Delaware Botanic Gardens is another great place to search for unfurling ferns now and enjoy their cooling presence later this summer. There are painted and Christmas ferns in the Dunham Garden, at the main entrance; autumn and Christmas ferns by the Creamery ice cream shop; and still more Christmas ferns in the native garden.

In shady or partial shady conditions, ferns can be the workhorse of the garden. They can be used as groundcover in places where few other plants will thrive and also spotlighted as specimen plantings, notes Barton. Most varieties are low maintenance, drought tolerant and deer resistant. A few ferns will even tolerate full sun, as long as they have adequate moisture.

On June 19, Linda Eirhart will lead a fern workshop that covers the basics of fern botany and cultivation as well as an introduction to the best ferns for this area. 1:30 p.m.-3:30 p.m. Winterthur Museum and Gardens. To register, call 888-4600.

Largest crowd ever turns out for Ag Day 2013 festivities

May 2, 2013 under CANR News

Ag Day Bird showBeautiful weather, great entertainment and a variety of agricultural and environmental exhibits combined to make Ag Day 2013 the largest in history, with more than 8,000 visitors in attendance.

The record crowd of visitors gathered at the 38th annual Ag Day were able to see over 90 interactive exhibits and witness a variety of demonstrations including a beehive demonstration, a free flight bird show, a Seeing Eye dog demonstration, a tree climbing exhibition, live bands featuring University of Delaware faculty and professionals, and the unveiling of a portrait of Robin Morgan, former dean of the College of Agriculture and Natural Resources (CANR).

New to Ag Day this year were horse-drawn wagon tours of the UD farm put on by Circle C Outfit from Bridgeville, Del., which featured Rick, one of the horses from UD’s herd.

Always popular at Ag Day are the many plant sales by the University of Delaware Botanic Gardens (UDBG), UD Horticulture Club and New Castle County Master Gardeners, and the ice cream from the UDairy Creamery. This year the UDairy Creamery sold ice cream to over 3,600 patrons, practically doubling the amount that they sold at Ag Day 2012.

Also popular was the free flight bird show, which is put on by a CANR alumnus. “One of the unique things that we’ve been able to offer the past few years is we have an animal science alum who does animal training and behavior, who travels around the U.S. to train educators to conduct live bird shows,” explained Katy O’Connell, communications manager in CANR. “At Ag Day, he offers two free flight bird demonstrations where he has macaws, vultures, hawks and even chickens that he trains to do live demonstrations.” The crowd for the 2 p.m. showing topped 500 audience members.

CANR Dean Mark Rieger, having been hired in August 2012, was on hand for his first Ag Day and welcomed those in attendance, saying, “We hope that you learn something about agriculture, and we also hope that you learn something about natural resources — that’s the other part of our name. If you take the farm tour and you go on the carriage ride, you’re going to see wetlands, you’re going to see streams, you’re going to see woods, you’re going to see songbirds. If you go inside, you’re going to have a wildlife display in there, an entomology display, and things like that. So there’s a lot of different things here today; make sure you get around and see all those things.”

Rieger also thanked O’Connell, who led the organization of the event, along with eight undergraduate students, Kim Yackoski, CANR assistant dean, and Latoya Watson, CANR academic adviser, before handing the microphone over to Tom Sims, CANR deputy dean, who had a special presentation for Morgan.

Robin Morgan’s portrait

The portrait — a CANR tradition that sees each dean get their portrait painted and hung in Townsend Hall — was unveiled by Rieger and Sims.

Of Morgan, Sims said, “It was my privilege to work with [Morgan] as associate dean and deputy dean for nine years. She really was committed to our students, our undergraduate students, she was committed to our faculty, she built our faculty by hiring many of our current faculty members and was committed to agriculture and natural resources as she demonstrated throughout her tenure as dean.”

After unveiling the portrait, painted by Kellie Cox, a UD alumna, Sims continued saying, “This is just a small way of saying thank you to Robin for all that she’s done. She’s now back on the faculty getting ready to teach a big class this fall so her commitment to agriculture and our students just goes on and on.”

Rieger echoed these sentiments adding, “I want to thank Robin for coming out today and all the things that she did for the college. It makes my job a lot easier having to step into her shoes when she has done so much for the College of Agriculture and Natural Resources.”

Bloom season kicks into high gear for garden enthusiasts

April 11, 2013 under CANR News, Cooperative Extension

In April, bloom season kicks into high gear in Delaware. In fact, it might be the single best month to get outside and enjoy the views at the area’s world-class gardens.

At Winterthur, the Winterhazel Walk will soon be the star of the show, reports Linda Eirhart, assistant director of horticulture for the museum, which features a 60-acre naturalistic garden in the midst of nearly 1,000 acres of land.

Delaware bloom season kicks off“The cold weather has held things back but before long the Winterhazel Walk will dazzle with its combination of soft yellow winter hazel and the warm lavender of Korean rhododendron. This is under planted with hellebores, which are still going strong,” she says.

These species are non-native but many of Winterthur’s native plants will soon be in bloom, too. Bloodroot is a sweet little perennial with pure white, cup-shaped flowers. You can find it in Azalea Woods and other wooded areas and thickets throughout the property.

Spring beauty is another little charmer, sporting white petals with stripes that vary from pale pink to bright pink. Like bloodroot, it grows in woodlands. Pay attention to weather conditions during your visit to Winterthur. If it’s warm and sunny, spring beauty will open its petals but on a cloudy day or at night the petals close up and nod downward.

Winterthur’s bluebells aren’t in bloom quite yet but the buds have appeared and will soon burst into bloom. Eirhart says that bluebell is her favorite native wildflower.

“I love the bluebell’s shades of blues and the touch of pink and purple you can get in the blossoms,” she says. “Between the color of the flower buds and the last fading flowers, there is a good length of time of color interest.”

Sue Barton also is a fan of Virginia bluebells, which grow in clusters near the creek on her property. “It’s fun to come upon a mass of bluebells while walking in the woods,” says Barton, who is ornamental horticulture specialist for University of Delaware Cooperative Extension.

But it’s flowering redbuds, not bluebells, that signal that spring has sprung to Barton.

“The redbud has an extremely colorful, dark purple or pink flower and an unusual habit of flowers borne directly on the stem,” she says. “I like the ‘Forest Pansy’ cultivar because of its attractive bronze foliage.”

This small native tree grows wild in many of Delaware woodlands. As you buzz down I-95, check out the large stand of redbuds by the roadside, just south of Wilmington. For a more leisurely setting to enjoy redbud blooms, head to the University of Delaware Botanic Gardens. You can find flowering redbuds there, and a whole lot more.

“In bloom, or soon to bloom, are a number of natives, including silverbells, fothergilla, serviceberry, redbud, dogwood and pawpaw,” says Claudia Bradley, nursery coordinator for the UD Botanic Gardens.

She is particularly fond of fothergilla and tends to it not only in UD’s gardens but also in her own home garden. “I always look forward to seeing the fothergilla in flower,” says Bradley. “I like its bottlebrush white flowers now and, then, in fall, its awesome red color.”

Mt. Cuba Center is another great place to check out spring blooms, especially since it’s expanding its public hours. Starting April 19, you won’t need a reservation to visit on Fridays and Saturdays, from 10 a.m. to 4 p.m. (From May 3 to July 26, the gardens will stay open until 7 p.m. on Fridays.)  Guided tours will still be available by reservation on other days and times.

Chilly weather delayed some of the blooms at Mt. Cuba, just as it as at Winterthur and other area gardens. But now that it has warmed up, native spring ephemerals will soon emerge in Mt. Cuba’s woodlands, reports Jeanne Frett, a research horticulturist at the center. Look for flowering liverleaf, trout lily, bloodroot, rue-anemone, cut-leaf toothwort and Dutchman’s breeches.

Trees and shrubs also are starting to bloom at Mt. Cuba. If you’d like some April flowering shrubs in your own yard, Frett suggests American bladdernut and spicebush.

“Both of these are found locally in the woodlands and at Mt. Cuba Center,” says Frett. “They’re very appropriate choices for creating your own naturalistic gardens using locally native species.”

Spicebush is one of Delaware’s most common native shrubs. On the female plants, small clusters of yellow flowers appear now, and later develop into red fruit. American bladdernut isn’t the most beautiful April bloomer but it could be the most interesting.

“More of a curiosity than a specimen shrub, the American bladdernut has bell-shaped flowers that develop into three-lobed, inflated, brown papery capsules later in the season,” says Frett.

Delaware Nursery and Landscape Association selects 2013 Plants of Year

March 11, 2013 under CANR News

Rhus aromatica 'Gro-Low' can be found at the UD Botanic GardensIn her role as executive director of the Delaware Nursery and Landscape Association, Valann Budischak’s responsibilities are wide-reaching. She’s even expected to organize an annual beauty pageant. In this case, however, the contestants are plants, not people, and strength and vigor are just as important as good looks.

The association has just announced its 2013 Plants of the Year and both the woody plant – Rhus aromatica ‘Gro-Low’ – and the herbaceous winner – Heuchera macrorhiza‘Autumn Bride’ — are much more than just pretty faces.

“The idea behind the ‘Plant of the Year’ designation is to give recognition to hardy, attractive plants that are well-suited to local growing conditions but may be a bit under-the-radar screen,” says Budischak. “Heuchera macrorhiza ’Autumn Bride’ makes a great groundcover if you have shady areas, like I do. Or, if you have sunnier conditions, consider Rhus aromatica‘Gro-Low’ for its multi-season interest.”

Rhus aromatica ‘Gro-Low’ is a cultivar of Delaware’s native fragrant sumac. It’s a dense, low-growing shrub that looks good almost every month of the year. In spring, tiny yellow flowers bloom at the twig tips before the foliage appears. During the growing season, Rhus aromatica ‘Gro-Low’ has glossy, dark-green leaves, which are accompanied by small clusters of hairy, red berries in late summer. In fall, the leaves turn brilliant shades of orange and red.

“This sumac cultivar makes an impact when planted in masses,” says Budischak. “When I am asked to recommend a plant for sloped areas, I usually mention Rhus aromatica ‘Gro-Low.’ Because it has the ability to develop roots as the stems touch the soil, it’s great for stabilizing banks and slopes.”

Birds, butterflies and other wildlife like it, too.

Budischak has bunches of Heuchera macrorhiza ‘Autumn Bride’ in her backyard. She loves this groundcover’s large, velvety foliage, which gives this plant its common name of hairy alumroot. Although it’s billed as being tolerant of full sun to deep shade, Budischak begs to differ. “Around here it’s not as happy in full sun unless you give it adequate moisture.”

Heuchera macrorhiza is a plant that really comes into its own as the growing season progresses.

“In spring it’s a nice, fuzzy, light green groundcover,” says Budischak. But by summer the large leaves are eye-catching. Then, in late summer, when almost everything else in the garden is solid green, Heuchera macrorhiza erupts in fountains of tiny white flowers that rise up out of the foliage mound on slender fuzzy stems.

The ‘Autumn Bride’ cultivar of Heuchera macrorhiza is considered to be tough and easy to grow. “It is great for covering bases of trees or other spots that get little moisture,” says Budishak. It also does well in moist shade.

The University of Delaware Botanic Gardens has a nice display of Heuchera macrorhiza‘Autumn Bride’ at the entrance. People also can find Rhus aromatica ‘Gro-Low’ there, planted alongside a fence next to the herbaceous garden.

The folks at the Delaware Nursery and Landscape Association aren’t the only ones holding beauty pageants for plants. The Perennial Plant Association recently named Polygonatum odoratum “Variegatum” as its 2013 Perennial Plant of the Year. Commonly known as variegated solomon’s seal or striped solomon’s seal, this shade-loving plant is a great companion to ferns, hostas and astilbes. In mid- to late spring it produces small, bell-shaped, white flowers. Its sweet fragrance makes it a great choice along a pathway.

UD horticulturalists see understated attractions of winter landscape

January 26, 2012 under CANR News, Cooperative Extension

The lyrics of “California Dreamin’” by John and Michelle Phillips are well known and appropriate for the season: “All the leaves are brown, and the sky is grey, California Dreamin’ on such a winter’s day.”

Although many yearn to flee the First State during the long slog of winter, not everyone is dreaming of California. For every Delaware gardener poring over seed catalogs and wishing for spring, there’s another gardener like John Frett who’s outside every day enjoying the landscape, regardless of the weather.

Frett, the director of the University of Delaware Botanic Gardens (UDBG), loves winter and spends time in his yard or the botanic gardens every day, all year long.

“I grew up in Chicago and lived in Maine for three years,” says Frett. “Delaware doesn’t know what cold weather is.”

Beyond a hearty constitution for the cold, Frett has an appreciation for the understated attractions of the winter landscape.

“The structure of the trees, shrubs and woody plants are more evident in winter when there are fewer things competing for your attention,” says Frett.

At the 15-acre UD Botanic Gardens, the leaves are long gone (evergreens excepted) so it’s easy to see that trees come in all shapes and sizes. There are columnar, round, conical, broad-spreading, upright-spreading, weeping and elliptical trees in the gardens. And a wide range of texture is now revealed, from the peel-away bark of the paperbark maple to the ridged and furrowed bark of the tulip poplar.

But it’s not just a lack of competing attractions that makes the winter landscape visually arresting for Andrew Olson, public landscape manager for the Delaware Center for Horticulture. He points out that the weaker winter sun casts a different light on things.

“The lower angle of the sun in the winter really highlights grasses and garden structures,” says Olson. “Even the silhouettes of trees ‘pop’ in the waning afternoon light. A garden or natural landscape that may seem brown and bleak can be spectacular as the sun rises or sets.”

Carrie Murphy, New Castle County horticulture agent for UD Cooperative Extension, notes that a landscape’s backbone is completely revealed in winter. “Everything is completely naked and the landscape’s overall shape and structure becomes a focal point.”

“I also appreciate how sounds move through a winter landscape — everything is much more audible — the whipping winds, rustling leaves and movements of wildlife,” she says.

Eileen Boyle looks for the small details in the landscape. “While the perennials sleep off the winter and the bulbs wait their turn, I am enjoying the daily show of the ferns, mosses and other little plants that are last to go dormant,” says Boyle, a horticulturalist at Hagley Museum and Gardens.

Fellow Hagley horticulturalist Renee Huber says that she appreciates the structure of beech and sycamore trees in winter.

“I always enjoy the sycamore trees against the Brandywine this time of year; they’re like gentle giants with white and gray blotched bark,” says Huber.

Sue Barton, UD Cooperative Extension specialist for ornamental horticulture, likes the sycamore in winter, too. Other favorites include river birch, winterberry holly and the Emerald Sentinel variety of Eastern red cedar, which has vivid blue fruit.

Bob Lyons, director of UD’s Longwood Graduate Program in Public Horticulture, admits that he doesn’t much like winter. However, he does appreciate the architecture of trees now, especially when they’re outlined by a wet snow.  He particularly enjoys sweet gum, tulip poplar and deciduous hollies.

If the winter landscape looks enticing — that is, until you read the forecast and hear the winds howl — Olson has just two words of advice: “get outside.”

“Put on some layers and get out there,” he says. “You will be so glad you did.”

Here are some of the things to see in the late-January landscape:

• At the Delaware Center for Horticulture’s gardens, which are free and open to the public, a bloodtwig dogwood (Cornus sanguinea ‘Winter Flame’) gets lots of attention this time of year because of its intensely colored red and orange stems. Also look for the black pussy willow, which is beginning to display purplish black catkins. The Kentucky coffee tree, paperbark maple and river birch also look great this time of year, says Olson.

• Evergreen fans will want to check out the UD Botanic Gardens, which has a large collection of both conifer and broad-leaf evergreens. Native species include the loblolly pine and American holly. And you’ll find many other hollies — the UDBG features 50-plus varieties and is a test arboretum for the American Holly Society.

• At Hagley Museum and Gardens, snowdrops are in bloom in front of the Hagley residences and skunk cabbage is blooming in the woods and by the river. Boyle notes that the bright orange rose hips on old-fashioned antique variety roses provide perching and food for local birds.  Hagley arborist Richard Pratt loves Hagley’s osage orange in wintertime. “It stands like a large bronze sculpture with its deeply furrowed copper-colored bark on its majestic trunk and its crown spreading high and wide into the sky,” says Pratt.
