This decidedly hardy Agastache brings a new color palette with its long racemes of smoky blue violet flowers that never seem to stop coming. It remains compact in a container with an early pinch and is in flower from July to frost. It has survived wet and dry, and warm and cold winters in Pennsylvania where it has been in the ground since Spring 2000. Hardiness beyond zone 6 is unknown.
Definately a WOW! plant. Chartruse Coleus-like foliage is incredible on its own, but the blue bottlebrush flowers in mid summer top it off beautifully. Very hardy and will self sow. Benefits from a little shade in production to protect leaf color.
Profuse show of butter yellow lantern flowers from April to May. Its short stature, delicate color and mid spring bloom time make it an ideal companion for spring bulbs! Spotted by Richard Simon of Bluemont Nurseries, Monkton, MD. Named for the nearby small town of Corbett.
A marvelous long-blooming, bright white selection of swamp milkweed. Clear white flowers and dark green foliage make the colors of the hundreds of visiting butterflies glisten in the sunlight.
A naturally compact form with deep purple flowers in August and September. Eye-popping with Solidago 'Golden Fleece'. One of the most garden-worthy native selections out there. A fine introduction from the Mt. Cuba Center.
Elegant spikes of creamy yellow blooma grace tidy blue green foliage in early summer. Long-blooming and tough, a dazzling addition to the native plant palette. A hybrid of B. sphaerocarpa and B. alba, found by Rob Gardener of NC Botanical Gardens.
A native ground cover, this plant is known for both it's foliage and flowers with toothed, light green, triangular leaves and dark yellow, slightly notched, star shaped flowers that bloom well above the foliage and have contrasting brown stamens. The flowers bloom abundantly in the spring and fall, but tend to die down in the heat of the summer except in the cooler zones.
A North Creek original, this selection of C. pubescens var. pubescens blooms non stop from mid-summer until October here with saucer-like flowers over low spreading, slightly fuzzy foliage. An easy self sowing plant, when happy. Likes hot, bright, well-drained spots, but is not fussy at all. An easy native for sun or part shade.
Winner of the 2001 RHS Award of Garden Merit, this Threadleaf Coreopsis is just a little bit shorter than 'Moonbeam'. 'Zagreb' has bright yellow flowers that sit atop tall, erect, lacey, somwhat mound forming, delicate (thread leaf) looking, green foliage that has an airy appearance. The flowers are abundant and bloom continuously throughout the entire summer. Removal of the dead blossoms encourages longer blooming and healthier flowers. Truly a colorful sight. Great in rock gardens and gardens with poor soil. Makes a good cut flower.
Our own selection of this species has dark blue snapdragon flowers covering a low, thick mound of rosemary-like foliage in early summer. Compact in a container and very easy to grow, just treat it as you would a Dianthus. It has been reliably hardy in Landenberg through rain and drought for five winters. Needs good drainage.
Exceptionally large flat-topped flowers in early to mid summer. Sundown is a selection with a deep orange cone surrounded by broad petals in susnset shades of orange and rose. This plant is trouble free and easy to grow!
Stands of these pure white flowers in an open garden leaves one with a free spirited and wild feeling as these tall prairie flowers come alive with butterflies. The flowers, blooming from July to September, are supported by bold stems. Overall, striking and different.
Like others in this genus, 'Gateway' is no exception in it's power to attract butterflies with its huge bright mauve pink flowers clusters atop deep wine red stems. More compact and shorter than others in this species. July to September bloom makes 'Gateway' a bold and dramatic display when planted with Rudbeckia 'Autumn Sun' or tall ornamental grasses. Outrageous!
Named by Dr. Alan Armitage, of the University of Georgia. Vigorously spreading, deep purple clusters from June to November. Excellent clean, deep green foliage with a trailing habit. Has been surviving the winter here lately, but it gets a very slow start in the spring. Best treated as an annual zone 6 or less.
