Vernonia

Culver's Root

These vigorous American denizens promote an obliging stalwart demeanor plus welcome late summer flowers. A nectar feast for the butterflies, Vernonia can be peppered throughout meadow plantings and native landscapes, accompanying chums such as Helianthus ‘Lemon Queen’, Eupatorium ‘Riesenschirm’ and Sporobolus ‘Tara’.

Wandering amidst Arkansas and Oklahoma’s rocky outcrops and flood plains, this graceful easy-care perennial pays homage to George W. Letterman, a highly regarded loner-type botanist who scoured the Missouri Ozarks searching for unusual plants. Vernonia lettermannii’s steadfast taproot sends forth well-branched, sturdy upright stems cloaked with ultrathin lanceolate green leaves, while hundreds of close-knit royal-purple flowers, held in countless small clusters, roost above. Relished by bees, moths, skippers and butterflies, the late summer flowers plus soft-looking deer-proof demeanor can stabilize slopes, garnish a cut arrangement or enhance water-wise gardens, natural-style plantings and perennial borders. Sunshine galore, sharp drainage and moderately moist to dry soil ensure its prismatic fine textured allure.

Blooms August–September

Size: 2-1/2' – 3-1/2' high x 18" – 2' 0" wide.

Hardy to zone 4.
