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.
The tall, thin spikes of Blue Vervain grace the wet meadows of the US in July and August. Verbena hastata is a short-lived perennial that readily self sows where happy. A great plant for pond's edge where it seeds in between sedges and rushes and cheerfully holds its own.
This selection of the Arkansas native comes to us from Dr. Allan Armitage's trials at the University of Georgia. It has lovely fine foliage like Amsonia hubrichtii and is a compact, well-branched and vigorous plant. In late summer it is covered with true purple flowers that attract plenty of butterflies. Found in rocky flood plains, Vernonia lettermannii is very tolerant of hot, dry locations, yet can withstand brief periods of inundation.
New York ironweed
Deep purple haze in damp meadows, roadsides and pastures. A lovely native that adapts well to any moist location.
Deep blue-purple spikes are decidedly upright and plentiful. This variety is compact and slowly spreading. Superb!
Big dramatic spikes of white Veronica-like flowers in July and August. Very tough and long-lasting once established. Found in open woods, moist meadows, and praries east of the Rockies.

From the gardens of Mt. Cuba Center, North Creek is delighted to introduce this tough native groundcover. Easily identified by trailing stems and delicate lavender flowers, 'Silver Gem' forms a dense, tidy mat of attractive silver foliage. Flowers appear in March and persist into autumn. Our plant trials have proven 'Silver Gem' to be exceptionally drought tolerant and happiest in part to full shade. Pot in quarts or gallons for early spring sales.
Bright, golden-yellow, 5-petaled flowers bloom early to late spring creating a striking accent against evergreen, trifoliate leaves. Flowers and foliage appear on separate stalks; foliage spreads by rhizomes just below the soil surface. A multi-seasonal, ornamental groundcover.
Golden clusters of 3-4" umbels in May and June. Deep green, leathery, handsomely divided basal foliage. Native to wooded bottomlands, stream banks, moist meadows, and floodplains east of the Rockies. Very attractive to butterflies.
