Regional Picks: Best Natives – Southeast

Fine Gardening – Issue 173

1. ‘Purple Smoke’ Wild Indigo

Name: Baptisia ‘Purple Smoke’

Usda Hardiness Zones: 4 to 9

Size:3 to 4 feet tall and wide

Conditions:Full sun; lean to average well-drained soil

Dark charcoal stems and gray-green foliage, typical of white wild indigo (Baptisia alba, Zones 5–8), are topped with enchanting, lupinelike flowers that are smoky violet with a purple eye. Numerous flowers first open low on the bloom spike and ascend, with the flower stalk topping out at 4 feet tall. Mature plants three to four years old can bear more than 50 blooming stalks in springtime gardens. This exciting, naturally occurring hybrid of white wild indigo and blue wild indigo (B. australis, Zones 3–9) offers the best of both species and was found, watched over, and nurtured by Rob Gardner, former curator of the North Carolina Botanical Garden.


2. ‘Cosmic Eye’ Coreopsis

Name: Coreopsis ‘Cosmic Eye’

Zones:5 to 9

Size:24 to 30 inches tall and wide

Conditions:Full sun; well-drained soil

Darrell Probst, renowned for his work with epimediums (Epimedium spp. and cvs, Zones 5–8), has turned his attention to Coreopsis, with predictably stunning results. ‘Cosmic Eye’ is one of the Big Bang™ series, sporting daisylike bicolored flowers of burgundy with golden yellow tips. This fairly compact coreopsis blooms from midsummer into fall and is suitable for containers or the front of the border. Bred for colder climates, it is reliably hardy in Zone 5 and, perhaps, Zone 4 with careful placement. Keep it deadheaded for an even longer bloom time.


3. ‘Frosted Violet’ Coral Bells

Name: Heuchera ‘Frosted Violet’

Zones:4 to 8

Size:12 to 18 inches tall and 2 feet wide

Conditions:Partial to full shade; average soil

This outstanding cultivar brings an elegant presence to the shade. The leaves have purple, silver, and dark green tones that blend to create a rich mix that changes its color balance through the season. In early summer, flower spikes up to 30 inches tall are topped with tiny rose-pink blooms. This hybrid has substantial Heuchera villosa parentage, so it is well adapted to the hot, moist southeastern climate. Shade and drought tolerant, it is ideally suited for a woodland garden.


4. Seashore Mallow

Name: Kosteletzkya virginica

Zones: 6 to 9

Size: 5 to 6 feet tall and 3 to 4 feet wide

Conditions:Full sun; moist to average soil

Pale pink 3-inch hibiscuslike flowers appear from late summer through fall on 5- to 6-foot stems. Typical of all hibiscus, the flowers open daily then close, with a fresh crop of blooms appearing the next day. Seashore mallow is suited to full sun or a half-day of afternoon sun. Native to salt and brackish marshes, swamps, and other wet areas along the east and gulf coasts, this plant appreciates supplemental irrigation during drought. It is beautiful in the middle or rear of the border.
