Golden Groundsel (formerly Senecio) is a very adaptable native groundcover which produces masses of yellow daisies in spring. Packera aurea flourishes in shady sites, both moist and dry. The green foliage is finely incised and attractive, and the flat topped flower clusters are held above the basal clumps on sturdy stems which makes them good cut flowers. Packera aurea is an excellent groundcover choice for rain gardens, wet meadows and moist to dry woodlands.
'Bowl of Beauty' Herbaceous Peony blooms in late spring and makes a beautiful show with fuchsia pink anemone-form flowers. The dark pink guard petals surround creamy-yellow petaloids. Paeonia 'Bowl of Beauty' makes an excellent long stemmed cut flower, with an attractive fragrance.
'Bartzella' Itoh Hybrid Peony has sulfur yellow double flowers in May and June, held on short stems above green disease-resistant foliage. The blooms have red center flares on petals, and 'Bartzella' makes a lovely short cut flower. Roger Anderson of Wisconsin introduced Paeonia x 'Bartzella' in 1986, after years of hybridizing work.
PRN Preferred: A heavy bloomer with bright yellow flowers. Since is it an Itoh, the foliage looks good all season long.
'Cora Louise' Itoh Hybrid Peony is one of the more vigorous Itoh introductions, bred by Roger Anderson of Wisconsin. It combines excellent hardiness with extremely large showy blooms. The 10" flowers have white petals which are maroon at the base, surrounding the yellow stamens. The form is semi-double and the flower production in May is plentiful. Like all the intersectional Peony hybrids, Paeonia 'Cora Louise' is a wonderful tough addition to the perennial garden.
'Old Rose Dandy' Itoh Hybrid Peony blooms in May and June, with large single copper petals enhanced by brick-red flares and yellow stamens. Since 'Old Rose Dandy' is an intersectional hybrid between Tree Peonies and Herbaceous Peonies, the woody stems are quite short and are vigorously covered with handsome disease-resistant foliage. A cross by Chris Laning in 1993.
We grow an outstanding selection of unique Garden Peonies, many of which we have grown for years in our own gardens with great delight. Heights range between 2 and 3' and plants are hardy to zone 3 and 4. Unusual flower forms, both double and single, make great cut flowers. All are deer resistant! Please visit the website for specific varieties and descriptions.
The Peony World has found a significant Holy Grail with the introduction of beautiful crosses between Tree and Garden Peonies. Toichi Itoh of Japan made the original breakthroughs in 1948, but selections resulting from this work have only recently become available. The flowers range from semi-double to double, in clear bright colors from pink, yellow, and lavender to orange, rose and red. The habit is somewhere between the two species, with short woody stems and vigorous green deciduous foliage. See our availability list for specific varieties.
Wild Quinine or Feverfew is an interesting native perennial with a number of unusual small wooly white flowers borne in flat-topped showy corymbs. The fragrant green leaves are contrastingly large, making a good setting for the delicate long-lasting blooms. Parthenium has a very long flowering period from late May into August, making it a wonderful back-of-the-border perennial or woods edge softener. Formerly used as a medicinal plant, Wild Quinine is unpalatable to deer and other pests.
'Blackbeard' Beardtongue has beautiful foliage in shades of eggplant and dark purple. The color stays intense throughout the summer and is topped by deep purple stems bearing showy lilac to pink open faced flowers. Penstemon 'Blackbeard' makes an excellent long lasting cut flower, and when finished blooming in the garden, the seedheads remain deep purple and attractive. A Walters Nursery introduction.
‘Onyx and Pearls’ Beardtongue comes from Walters Gardens’ breeding program of new beauties. Penstemon digitalis ‘Onyx and Pearls’ is a taller, darker version of this adaptable native, with burgundy foliage and stems which are almost black. The white and pale lavender flower clumps are on tall clusters made even more striking by their black stems. ‘Onyx and Pearls’ blooms for a long period in early to mid summer, and makes an excellent cut flower. The beautiful dark foliage makes a showy rosette well into early winter.
'Denim 'n' Lace' Russian Sage produces sky blue flower spikes for an extended period in mid to late summer. The lacy blooms are produced on the tips of strong stems with grayish green airy aromatic foliage. The individual blue flowers on the spikes of 'Denim 'n' Lace' Perovskia are closely spaced so the clumps look fuller than other Perovskias, and the lavender calyces remain showy after the flowers are finished, extending the ornamental qualities. Excellent drainage is a must for this new introduction from Walters Gardens.
'Little Spire' Russian Sage has blue flowers in July and August, over silver-green aromatic foliage on a compact form, and is dry site tolerant. From Herbert Oudshoorn of Holland. 2020 PHS Gold Medal Plant!
‘Golden Arrow’ Fleece Flower blooms from July to early fall, producing lots of rosy pink to red flower spikes for a prolonged period. The large lance shaped leaves are gold to chartreuse, making a showy background for the blooms. Persicaria amplexicaulis ‘Golden Arrow’ is more compact than most Fleece Flowers, and is a good ornamental addition to the edges of rain gardens and ponds. ‘Golden Arrow’ performs best in partial shade.
‘Solar Fare’ Carolina Phlox is a disease resistant member of the Earlibeauty® series from Primrose Path’s breeding program. The large bicolored flowers have pink eyes surrounded by white, produced in showy panicles. The green foliage withstands hot and humid summer conditions and is mildew resistant. Phlox carolina ‘Solar Flare’ is a favorite summer nectar source for butterflies, sphinx moths and hummingbirds.
'Blue Moon' Woodland Phlox blooms in April and May, producing large violet blue fragrant clumps of flowers on delicate stems. Phlox divaricata 'Blue Moon' is a particularly showy example of our native groundcover, naturalizing well in woodland settings. An introduction by the New England Wildflower Society.
'Blue Paradise' Garden Phlox has fragrant flowers that open pale blue and darken to violet blue in July and August. It has good mildew resistant foliage. All Phlox varieties we grow are disease resistant cultivars.
'David' Garden Phlox has fragrant white flowers in July and August and disease resistant foliage. 2002 Perennial Plant of the Year. From FM Mooberry of the Brandywine Conservancy, where Phlox paniculata 'David' was found as a seedling.
'Glamour Girl' Garden Phlox blooms prolifically in mid to late summer. The bright coral pink flower panicles are displayed on dark stems above mildew resistant green foliage. Phlox paniculata 'Glamour Girl' has a lot to offer mixed perennial borders, with height, fragrance and butterfly and hummingbird appeal. An introduction from Walters Garden's breeding program. Will rebloom if deadheaded right after the first bloom flush.
PRN Preferred: The bright coral flowers and dark stems are a real standout in the garden.
'Jeana' Garden Phlox is an unusually mildew-resistant Phlox with bright lavender-pink flowers which have a sweet fragrance. 'Jeana' blooms for an extended time from mid summer to early fall. It was found by (and named after) Jeana Prewitt of Nashville, Tennessee, and the North Creek people got us all enthusiastic about it. In the Mt Cuba Phlox trials, 'Jeana' was overwhelmingly the most attractive cultivar for all pollinators.
PRN Preferred: Have trialed Jeana for many years. Its foliage remains clean all season and it attracts the most butterfies of all the Phlox we grow. The best performing Phlox in Mt. Cuba's Phlox trials.
'Nicky' Garden Phlox has fragrant deep magenta-purple flowers in mid summer. Its very intense color make this and 'Laura' the favorite Phlox of Nanci Angle of Lawrence Landscapes. Introduced by Niche Gardens.
‘Red Riding Hood’ Garden Phlox produces large clumps of cherry red fragrant flowers in mid to late summer. The plants are somewhat compact, and the sturdy stems make Phlox ‘Red Riding Hood’ excellent for cut flower arrangements. The green foliage is more disease resistant if planted in full sun, with good air circulation.
The flowers in April of 'Candy Stripe' Moss Phlox are pink and white stripes, over creeping thread-like green foliage. Needs good drainage.
'Emerald Blue' Moss Phlox is covered with lavender blue flowers in April. Creeping green thread-like foliage is perfect for rock gardens and around walks. Prefers good drainage.
‘Emerald Pink’ Moss Phlox makes a dense carpet of delicate green foliage which somewhat resembles Moss (hence the name). Phlox subulata ‘Emerald Pink’ is covered with masses of bright pink notched flowers in April and May. Since it is a northeast native, Moss Phlox is a good suggestion for naturalizing in sunny well-drained locations where a low groundcover is needed. It also is a lovely addition to rock gardens.
'Scarlet Flame' Moss Phlox has scarlet-rose flowers in April over creeping green thread-like foliage. Works well in rock gardens. Needs good drainage.
'Snowflake' Moss Phlox becomes covered with white flowers in April over creeping green foliage. Excellent for rock gardens, walls and paths. Best in well-drained soil.
'Fashionably Early Crystal' Garden Phlox is another beauty from the prolific plant breeder Hans Hansen. A cross between P. maculata and P. paniculata, 'Fashionably Early Crystal' combines great attributes of both parents. The thick leathery leaves are narrow and highly disease resistant, and the habit is stoloniferous, the large fragrant flowers are white with tiny lavender eyes, and produced in quantity for a month in early summer. If deadheaded, there is often some reblooming in fall.
‘Fashionably Early Flamingo’ Hybrid Phlox starts blooming in early summer and continues intermittently into fall if deadheaded. The flowers are lavender pink and produced in clumps on tall disease free stems. The habit is stoloniferous, so Phlox ‘Fashionably Early Flamingo’ will spread to make a wide patch eventually. The name refers to the earlier bloom period, 2 to 3 weeks before Phlox paniculata.
'Violet Pinwheels' is a beautiful Moss Phlox hybrid from Dr Jim Ault and Chicagoland Grows®. The habit is low and similar to Phlox subulata, but the flowers are a bright violet, a color hard to find in the subulatas. The petals are large and finely notched, resembling their "Pinwheel" name. This exciting new color option would look excellent in rock gardens and around garden paths. Needs good drainage.
'Wanda' hybrid Phlox was shared with Alan Armitage by the gardener who found this spontaneous seedling in her garden. During the testing in the UGC trial gardens, its long flowering period and number of pink blooms really made Phlox x 'Wanda' a standout. The habit is compact and full, with good disease and heat resistance. 'Wanda' would make a great container plant because it blooms most of the summer and even into the fall.
‘Ruby Slippers’ Solomon’s Seal emerges in spring with red stems supporting the clean green leaves along the length of the stems. Delicate pendant white flowers hang below each pair of leaves in late spring. The blooms are delicately fragrant, and the cut stems make an attractive addition to flower arrangements. Since Polygonatum ‘Ruby Slippers’ spreads slowly to make a solid mat, this Solomon’s Seal makes an excellent shade ground cover.
Variegated Solomon's Seal has white flowers in the spring, over green leaves with white edges. Polygonatum odoratum 'Variegatum' likes moist sites and will colonize slowly to form a large patch eventually. It is also surprisingly dry site tolerant. 2013 Perennial Plant of the Year.
Appalachian Mountain Mint has attractively fragrant foliage topped by spiky round silvery white flowers in late summer. The blooms are highly attractive to butterflies. Since Pycanthemum flexuosum spreads by underground stolons, it does a good job on slopes and stream sides. The fall foliage color takes on shades of red for added interest. Wet site and shade tolerant, as well as deer resistant.
As the summer advances the new leaves of Mountain Mint take on a silvery-white coloration to the point where they look like small white Poinsettias. The small pink flowers are a great butterfly attractant, and the foliage is deliciously aromatic. This plant is one of the significant late summer beauties on the High Line in NYC. Its rapid growth habit makes Pycnanthemum muticum a great groundcover.
PRN Preferred: Attracts the most pollinators we've ever seen, very critter resistant.
