PHS Gold Medal Winners Announced at 2013 Flower Show

The outstanding plants and products that have earned recognition as PHS Gold Medal winners were announced February  28 and exhibited at the 2013 PHS Philadelphia Flower Show. Visitors to the Show were able to learn about the habits of each of these cultivars and make plans to include them in their own landscapes.

For more than 30 years, the Pennsylvania Horticultural Society has honored and promoted plants of exceptional merit through the PHS Gold Medal program. Nominations come from home gardeners, designers, horticulturists, landscape architects, growers and owners of nurseries–anyone who loves trees, shrubs and vines.

The winners are chosen for their beauty, performance, and hardiness in the growing region of Zones 6-7 (covering the region from Philadelphia to Harrisburg, and from New York to Washington, D.C). When gardeners acquire a Gold Medal winner, they can be assured the plant will exhibit standards of excellence for hardiness, disease and pest resistance, and ease of growing when planted and maintained as recommended.

The Gold Medal plants and products will be available for purchase at the PHS Store at the Flower Show, and at PHS Meadowbrook Farm in Abington Township, PA, this spring.

The winning plants are:

goldmedalhinokiHinoki Cypress Chamaecyparis obtusa ‘Nana Gracilis’
‘Nana Gracilis’ isn’t a new cultivar, but it is sorely under-used compared to dwarf Alberta spruce, which is the dwarf, pyramidal conifer that gets planted in so many housing developments. ‘Nana Gracilis’ grows upright and slowly like dwarf Alberta spruce, but it is much more bug-resistant.

Blue Velvet St. John’s Wort – Hypericum ‘Blue Velvet’ 
The carefree nature of St.John’s Wort is well known, but ‘Blue Velvet’ stands above the rest for distinctive blue foliage and extended flowering period with buttery-yellow blooms. In addition to being widely adaptable in full sun or part shade, it is a hybrid with native parentage that provides a bonus for naturalistic landscapes. With members of the St. John’s Wort genus being medicinal herbs, ‘Blue Velvet’ should continue to remain unpalatable to deer and a highlight in the landscape.

Black Tupelo Tree Nyssa sylvatica ‘Wildfire’      
‘Wildfire’ Black Tupelo has spectacular red-tipped new growth into summer, and it is one of the goldmedalblackgummost stunning autumn foliage choices.  It is the perfect companion for maples’ fall color. Its small black fruits make this tree an amazing native selection for wildlife interest. 

Dwarf Highbush Blueberry  Vaccinium corymbosum ‘Sunshine Blue’

This is an elite selection that is the epitome of what the PHS Gold Medal represents: seasonal interest, durably growing, and a reward to have in the garden. It can be used goldmedalhighbushas an ornamental shrub in the landscape, has fruit-bearing blueberry selection that is complemented by its blue foliage, and is a worthy choice for use as a hedge in the garden with its uniform habit of growth.

Superior products

The Gold Medal program has been expanded this year to include superb horticultural products and a mobile application that serves as an excellent electronic tool for gardeners. A PHS Gold Medal Product must have a leading role in the competitive landscape through novel features, outstanding value for the price, notable ease of use, attractive aesthetic, and a demonstrable boost to the customer’s productivity.

The winners are:

Lesche Digging Tool
This is the best and last digging tool you will ever need for your garden. Lesche Digging Tools are made in the U.S. with a blade that is heat-treated for great strength. These products are so strong and indestructible that they are the digging tool of choice among soliders in Iraq and were used for the World Trade Center cleanup.

Organic Mechanics
Organic Mechanics produces all-natural, sustainable soils that provide superior results. Their soils, biochar, and compost tea are 100 percent organic, made with locally sourced ingredients, completely peat-free, and used by professional gardeners at arboretums and botanical gardens including PHS Meadowbrook Farm, Longwood Gardens, Scott Arboretum, and Chanticleer.

Leaf Snap
Developed by researchers from Columbia University, the University of Maryland, and the Smithsonian Institution, this free mobile app uses visual recognition software to help identify tree species from photographs of their leaves. This innovative app contains beautiful, high-resolution images of leaves, flowers, fruit, petiole, seeds, and bark, and a user-generated map that shows where these trees can be found near you.

Gold Medal Plants with Winter Interest Featured at Longwood Gardens

hawthornSince its inception in 1978, the Gold Medal Plant Award program of the Pennsylvania Horticultural Society has recognized trees, shrubs, and woody vines of outstanding merit. The program was originally conceived by noted nurseryman Dr. J. Franklin Styer, who realized homeowners and gardeners needed to learn about superior woody plants for their landscapes. These plants are evaluated and chosen for their superb eye-appeal, performance, and hardiness in the growing region of Zones 5-7. Many winners are hardy in a much broader geographic range.

When a gardener acquires a plant designated a Gold Medal winner, he or she can be assured the plant will exhibit standards of excellence for pest and disease resistance, as well as ease of growing, when planted and maintained by recommended methods. Gold Medal Plants are also chosen for their beauty through many seasons, whether it be foliage, flower, form, or bark.

Gold Medal winners can be found at Longwood Gardens year round. Click here for the map of those winners that exhibit winter beauty in the garden; the list includes several varieties hollies, witch hazel, evergreens, and more. Enjoy them at their peak form now with a winter visit to Longwood!

Volunteer Spotlight: Mia Mengucci

More than a few PHS staff members claim Mia Mengucci as one of their “star” volunteers. Mia has her hand in a bit of everything at PHS, from the Flower Show to Tree Tenders to the Gold Medal Plant Award program.

A Pennsylvania-certified horticulturist, Mia began her career working in greenhouses as a teenager. She then moved on to gardening for private clients and working in garden centers. She currently works at Primex in Glenside, PA.

Mia became involved with PHS during her application to join the Pa. Landscape & Nursery Association. Part of her training included a volunteer stint at the PHS Gold Medal Plant Award booth at the Flower Show about 10 years ago. “I was the volunteer who wouldn’t go away,” she laughs. Since then Mia has returned every year to help at the Show, as well as to talk about Gold Medal plants at other events.

“The Flower Show kicks off the gardening season for me,” says Mia. “It’s like reunion week; it’s a lot of fun. But I also take very seriously my role as a PHS representative.”

Knowledgeable, enthusiastic, and passionate about gardening, Mia is a graduate of the PHS Tree Tenders and Green City Teachers training programs. For the past eight years, she has been active with the West Mount Airy Tree Tenders group and leads a local Girl Scout troop in planting trees. She serves on the Tree Tenders Advisory Committee, gives lectures at the Gardener’s Studio at the Flower Show and for the PHS Gardening Series workshops, and volunteers at the PHS Kids Grow Expo.

“I love my PHS family,” Mia says.  “I can’t say enough about what PHS has done for me. I value the connection as I would value a very dear friendship—that’s why I say ‘yes’ to everything!”

PHS Announces New Batch of Gold Medal Winners

PHS has chosen four outstanding woody plants as the 2012 winners of the Gold Medal Plant Awards.

Since 1979, the Gold Medal program has honored and promoted woody plants of exceptional merit. Nominations for plants come from home gardeners, garden designers, horticulturists, landscape architects, nursery owners, propagators—just about anyone who loves trees, shrubs, and vines.

The winners are chosen for their superb eye-appeal, performance, and hardiness in the growing region of Zones 5-7. They also are judged for their beauty in many seasons, whether it be their foliage, flower, or structural form.

When home gardeners acquire a Gold Medal winner, they can be assured the plant will exhibit standards of excellence for hardiness, disease and pest resistance, and ease of growing when planted and maintained as recommended.

The 2012 Gold Medal winners are:

Cercis canadensis The Rising Sun™ (Cercis canadensis ‘JNJ’ PPAF) is a novel addition to the native eastern redbud roundup. Small-but-showy rosy orchid flowers climb the naked branches in early spring, attracting bees and butterflies. The distinctive bark is smooth tan with a yellowish cast. Emerging heart-shaped foliage is brilliant tangerine to apricot and reputed to hold its color well into fall, surpassing other gold-leaved redbuds. Heat tolerance, drought resistance, and cold hardiness are other desirable attributes.

Cornus officinalis ‘Kintoki’ (Japanese Cornel Dogwood) produces abundant clusters of radiant yellow flowers from March through April, blooming two weeks earlier than Cornus mas. Attractive exfoliating gray, brown, and orange bark develops with age. Reddish-purple, large, cherry-like, edible berries form by September. Fifteen feet high and just as wide, it is smaller than the species and puts on a spectacular display in full sun or partial shade.

Prunus lusitanica was first described by Linnaeus in 1753. The Portugal laurel is an evergreen shrub or small tree reaching 10 to 20 feet, but trees can grow up to 50 feet tall in the wild. Allowed to grow into a respectable cherry tree, it produces a profusion of gorgeous five- to ten-inch racemes or white flowers in late May, followed by small purple-red cherries that ripen to shiny black by autumn (caution: the leaves and berries are toxic). The shiny bright green foliage on red stems gains a bluish tinge in winter.

Viburnum x rhytidophylloides ‘Darts Duke’ is a superior selection prominent for its extra large, leathery, dark green leaves; massive 6 to 10 inch creamy-white flower heads in May; and heavy set of bright red fruit that changes to black in autumn. Growing 8 to 10 feet high with equal spread at a medium rate, this semi-evergreen shrub tolerates heavy shade or full sun and can potentially re-bloom in October if the season allows.

Discover What’s Growing in the Pops Up Garden

Hopefully you’ve had a chance to visit the PHS Pops Up Garden; if not, it is open today from noon to 2 pm. Be sure to pop in!

You may be wondering how a vacant, overgrown lot becomes a bustling garden. Well, the PHS team employed a variety of techniques and faced a good deal of challenges in their efforts to transform the 32,000 square-foot site.

Along the perimeter, grasses are growing naturally to create a meadow-like environment. But within this green band, PHS’s army of gardeners and urban farmers has created horticultural magic. The focal point is Temple University’s 2011 Philadelphia International Flower Show exhibit, “écolibrium,” which we’ll describe in detail tomorrow.

In the exhibit’s planters and surrounding area, look for trees, shrubs and vines from the PHS Gold Medal Plant program—which promotes durable and attractive woody plants that thrive in Zones 5 to 7. In the main production garden, PHS grows edible crops—like tomatoes, peppers, and arugula—that will be distributed to area chefs for special dishes on their menus, with proceeds going to the City Harvest program.

At the far end of the lot, alongside the Independence Blue Cross building, look for an open area where weekly programming takes place, including lectures, demonstrations, and family-friendly presentations.

In the rear of the Pops Up site is a vast cutting garden, along with some more traditional agricultural plants. Here, visitors will find everything from corn and grains to cosmos, sunflowers, zinnias, bachelor’s buttons, and cleome.

Take a walking tour when you visit and ask the on-site volunteers your burning gardening questions. We can’t wait to welcome you!
