Winner

Geum triflorum Prairie Smoke

The Freeman Medal Selection Committee, comprised of outstanding horticulturists from across the United States, was unanimous in its final decision about this lovely bloomer. Its early spring interest is followed by an amazing seed head display. As Seta writes: “the real magic occurs after pollination when the silvery pink, fluffy fruit, or achenes, appear…the stems slowly turn upright, and the seed heads begin to form, creating plumes which persist for one to two months.” Hence the name prairie smoke or old man’s whiskers gives a perfect description of the plant after bloom. Although prairie smoke is being challenged by taller, non-native plants in its native mesic prairie sites, it is readily adaptable to many other areas. Tolerant of poor soil, moderate drought, heat and humidity, Geum triflorum can be grown in sun or partial shade and is suitable for cottage gardens, prairies, meadows, and perennial beds. It is not favored by deer or burrowing animals. Geum triflorum nearly has it all! The selection committee was eager for this plant to become more available across the country and to be planted wherever it might flourish and spread its magic.

Aristolochia macrophylla Dutchman's Pipe

Aristolochia macrophylla, also known as Isotrema macrophyllum, is a deciduous native vine that can be used to create a lush living wall, a sheltering green roof, a thick ground cover, or an attractive privacy fence and it has been used in American gardens since the eigtheenth century.  Large, heart-shaped, densely overlapping leaves 6 to 12 inches long can quickly cover an arbor or trellis with attractive, glossy, deep green foliage and create a canopy impenetrable to the rays of the sun or moderate rain.  The common name derives from the plant's exotic pale yellow flowers that resemble a “Dutchman’s pipe." The flowers bloom in May and June among a swathe of large, fuzzy, heart-shaped, dark green leaves.  Aristolochia macrophylla is the host plant for the Pipevine Swallowtail Butterflies which lay their eggs in small clusters on young leaves or stems. When the eggs hatch, the leaves become an important food source for the growing caterpillars.  The unusual shape of the pipe blossom serves as a type of 'fly-trap,' attracting small insects that are temporarily held and released to carry pollen to the next flower.  Aristolochia macrophylla​ thrives in USDA zones 4 to 8, in sun to part shade, and in average to moist soil.  It is deer resistant and pollution tolerant, and it has no serious insect or disease problems.  It is a workhorse vine with an exotic look that would highlight a small or large native garden in the twenty-first century.

Viburnum rufidulum Rusty Blackhaw

Viburnum rufidulum (Rusty Blackhaw, Southern Blackhaw) is an incredibly versatile and underutilized native plant that can be used as a small specimen tree, a showy shrub border, an understory planting, or naturalized to provide habitat in a woodland setting.  With four-season interest, it is covered in spring and early June with striking 5 to 6-inch-wide clusters of small, creamy-white fragrant blooms that provide nectar for bees, butterflies, and beneficial insects.  Its showy flowers can be cut or dried and are surrounded by lustrous dark green, glossy, summer foliage. During fall, its clusters of dark blue berries are extremely popular with wildlife. The berries are edible and taste similar to raisins.  In fall, Viburnum rufidulum foliage puts on a brilliant display of autumnal colors which concludes with reddish-brown articulated bark that provides architectural interest in winter.  Viburnum rufidulum will grow 10 to 20 feet in USDA zones 5 to 9 in full sun or partial/deep shade.  It tolerates clay and poor soil and can be planted and naturalized in ravines and along rocky banks of creeks to prevent erosion.  It is resistant to disease, insects, and deer and, because it is tolerant of drought and pollution, it is an excellent option for public and urban areas.  You will probably not find this hearty, vibrant native in a big box store, but it is definitely worth asking your local nursery to get it for you for your home or community.

Carnegiea gigantea Saguaro

Carnegiea gigantea (Saguaro - pronounced "suh-WAHR-oh") is a stately, tall columnar cactus with large branches (arms) curving upward and a limited growing range in the arid Sonoran Desert. The saguaro is the iconic plant of the American Southwest and is indeed 'special' as a foundation species that supports many other species in the specialized ecosystem by providing food and habitat.  The 3-inch, creamy white and yellow blossom of the saguaro is the state flower of Arizona. These night-blooming flowers have a mother-of-pearl glow that is visible under the moonlight and attracts a variety of pollinators, including nectar-eating bats, birds, moths, and honeybees.  The bright red fruit is a food source for birds and has been harvested for centuries by native peoples. When the fruit falls to the ground, it is eaten by animals, especially coyotes and foxes. Birds use the saguaro for nesting and when water sources are not available, pack rats, jackrabbits, mule deer and bighorn sheep will eat the saguaro's flesh.  A saguaro requires little or no water, can live as long as 150 to 200 years, and grow to 40 to 60 feet tall. The saguaro has woody xylem, but it does not have bark. Despite the saguaro's fleshy exterior, the Desert Botanical Garden in Phoenix, Arizona, deemed the Carnegiea gigantea a woody plant.

Caltha palustris marsh marigold

Caltha palustris is a special spring ephemeral plant commonly known as marsh marigold.  This charming yellow plant produces both nectar and copious amounts of pollen which attract pollinating insects including flies, bees and butterflies. The seeds provide food for small wildlife and ducks. Caltha palustris grows in shade to sun, in wet and marshy areas, and along edges of streams, wetlands and rock crevices where it provides natural erosion control. For home use, it is well suited for rain gardens, water's edge and ephemeral ponds. Hardy in USDA Zone 2 to 7, it is one of the first to bloom and is often called "a harbinger of spring." Special Recognition was awarded to raise awareness that Caltha palustris needs promoting, planting and protecting.  An invasive plant, Ficaria verna, commonly known as lesser celandine, is a weedy, tuberous rooted, perennial that is also yellow, grows in wetlands and blooms in spring.  Native to Europe and eastern Asia, it is now naturalized in 19 states and can form large colonies covering several acres of wetland.  This aggressive growth displaces less vigorous native spring ephemerals.  If they grow side by side, the marsh marigold will lose. Caltha palustris is the better option for our native American gardens.

Carpinus caroliniana American Hornbeam

Michael Dirr states, “This plant has a lot to offer our landscapes in subtle beauty.” Carpinus caroliniana, also known as American hornbeam, ironwood or musclewood, due to its closely grained heavy, hard wood, is a small, deciduous hardwood, understory tree or multi-stemmed shrub native to eastern North America. Found in the wild along stream banks, moist woods, and in ravine bottoms, preferring moderate soil fertility and moisture, this species tolerates a wide range of temperatures, soils and moisture conditions, even several weeks of drought once established.  Slow growing in USDA Zones 3 to 9, American hornbeam can grow 20 feet high and 35 feet wide at maturity. 

Much admired for the bark, the smooth, grey trunk and branches exhibit a unique muscle-like fluting hence the other common name for the tree. In the spring, flowers bloom with male and female catkins.  The female catkins produce clusters of winged nutlets as they mature.  Long, oval, dark green, textured leaves turn shades of yellow, orange and red in the fall.

An attractively shaped globular tree, the catkins are a food source for numerous animals including squirrels, rabbits and beavers as well as turkeys, ducks, songbirds and grouse. The blossoms are a nectar source and the leaves a larval host for butterflies.

Resistant to disease, insects, ice damage and deer browsing, Hornbeam is suitable in a woodland setting, along a street, in a garden or as a bonsai specimen.

Aristolochia californica California pipevine

Endemic to northern California and native to the Sacramento Valley, San Francisco Bay area, Sierra Nevada foothills, USDA Zones 8 to 10, Aristolochia californica, commonly known as the California pipevine or California Dutchman’s pipe, is the exclusive food source for the larvae of the California pipevine swallowtail butterfly, Battus philenor hirsute. The red-spotted caterpillars eat the leaves of the pipevine and then use the flowers as a secure enclosure to undergo their transformation from larvae to butterfly. The leaves of the plant contain a toxin, which when eaten by the caterpillars, makes them unpalatable to predators.

 A deciduous woody vine, pipevine grows from rhizomes to a length of about 5 feet but can reach over 20 feet. The vine prefers part-shade and regular watering but can tolerate some drought. Common in moist woods and along streams in northern and central California, pipevine will spread out over open ground in the wild but can be trained on trellises or along paths in a garden providing a groundcover. The plant produces large green to pale brown, unpleasant, musty smelling pipe shaped blooms January through April that attract tiny carrion feeding insects that aid in pollination.  After the blooms, the vine sends out green heart shaped leaves. The leaves tend to dry and hang on the vine in the winter so it is suggested, in some sources, that one plants the pipevine with other plants.

The carnivorous yellow pitcher plant, Sarracenia flava, traps insects by using a vibrant yellow rolled leaf on top of a pitcher form bloom which can reach up to 3 feet in height. The upper part of the leaf is flared into a lid covering the tubular pitcher preventing excess rain from entering and diluting the digestive secretions within. Once the insect has landed on the upper regions of the pitcher, it is guided down towards the opening of the pitcher tube by short, stiff, downwards pointing hairs and brightly patterned guiding markings. The surface of the opening of the pitcher tube is studded with nectar-secreting glands. These nectars contain not only sugars, but an alkaloid which intoxicates its prey causing it to lose its footing and tumble to the bottom of the pitcher from which there is no escape. Because the pitcher plant traps insects for food, it does not require fertile soil and grows in acidic, low nutrient, damp wet bogs along the eastern seaboard from Alabama, through Florida and Georgia up the coastal plains to Virginia. It spreads by rhizomes and can be propagated easily by seed. In the life cycle of this plant, first the pitcher is produced; then large yellow flowers with long, strap like petals hanging umbrella style at the end of a two-foot scape. In the fall, the plant stops producing carnivorous leaves and produces a flat non-carnivorous leaf called a phyllodia. Photograph courtesy of W.

Trillium grandiflorum Great White Trillium

Trillium grandiflorum, (Common names: white trillium, great white trillium or white wake-robin) is a herbaceous perennial native to eastern North America ranging from Nova Scotia south to northern Georgia and west to Minnesota. Common in rich, mixed upland forests, T. grandiflorum is a spring ephemeral recognized by a whorl of three leaf like bracts standing up to 20 inches above the ground above which blooms its single large white three-petaled flower. T. grandiflorum is a slow growing plant whose seeds require two years to fully germinate, and flowering is usually determined by the surface volume of the leaf and the size of the rhizome which can take up to seven to ten years to reach optimal size for flowering. Due to the popularity of T. grandiflorum conservation concerns have been raised as a vast majority of the plants sold in nurseries are believed to be wild collected. When buying T. grandiflorum one must ensure that the plants are raised from seed. T. grandiflorum is thought to be self pollinating and its seeds are spread by ants. Occasionally it is thought that deer will spread the seed. As this plant is particularly attractive to deer, trillium foraging is often used as a gauge of the size of the deer population.
