Regions / Mid-Atlantic
Selecting plants suited to the Mid-Atlantic climate will be a key step to success.
Various initiatives have taken place to determine how well plants would withstand the cold winter temperatures (Plant Hardiness Zones) or when plants would start suffering from the heat (Plant Heat Zones).
The Mid-Atlantic region lies in USDA Plant Hardiness Zones 5 through 7 and in AHS Heat Zones 3 through 6. Stretching over a long expanse of territory, the Mid-Atlantic states are home to a wide range of weather and climate. However, generally speaking, this region enjoys 4 distinct seasons characterized by mild springs, hot and humid summers along the coast, but cooler in the mountains, mild falls, and chilly winters with some snow.
Actaea simplex 'Mountain Wave' (Baneberry) is a herbaceous perennial prized for its finely-divided, bronze leaves and eye-catching flower spikes. Standing out in late summer to early fall, attractive, dark stemmed fluffy spires, packed with deliciously fragrant creamy-white flowers adorned with a purple tinge, gracefully bob and sway in the breeze.
Grown for its attractive foliage and edible fruit, Actinidia arguta 'Issai' (Hardy Kiwi Vine) is a compact, deciduous climber that produces grape-sized, smooth-skinned, green fruits in late summer to early fall. While they are smaller than grocery store varieties, they are slightly sweeter and enjoy an excellent flavor.
Actinidia deliciosa (Kiwifruit) is a vigorous, deciduous, woody-stemmed, twining climber with broadly ovate, heart-shaped, lustrous mid-green leaves, 5-8 in. long (12-20 cm). Slightly fragrant clusters of cup-shaped, creamy-white flowers are borne in late spring.
Prized for its flamboyant foliage, Actinidia kolomikta (Variegated Kiwi Vine) is a large vigorous deciduous climber producing a striking foliage mass of heart-shaped leaves, 3-5 in. long (7-12 cm), some in solid green, others white-splashed green and others heavily variegated with pink.
Creating a sparkling effect, Actinidia polygama (Silver Vine) is a vigorous, scrambling/twining, deciduous climber producing a striking foliage mass of heart-shaped, dark green leaves, 3-5 in. long (7-12 cm), adorned with silvery-white tips - as if each leaf has been dipped in paint.
Incredibly attractive, Adiantum aleuticum (Maidenhair Fern) is a deciduous or semi-evergreen, perennial fern with graceful, bright green fronds which open like the fingers of a hand atop upright, shiny, purple-black wiry stems. Each finger is further divided into a series of triangular segments (pinnules).
Incredibly attractive, Adiantum venustum (Himalayan Maidenhair) is a deciduous fern, almost evergreen in mild areas, with broadly triangular fronds composed of many small fan-shaped segments. Emerging in late winter to early spring, the new fronds display a charming salmon flush before maturing to fresh spring green.
Agapanthus 'Donau' is a lovely African Lily with showy rounded clusters of star-shaped, pale-blue flowers adorned with dark-blue central stripes.
