Prairie plant, somewhat reminding soy bean plant, but with long racemes of purple-blue flowers. Unknown in horticulture, but probably very promising.
Up to 3' tall, and slowly spreading into wide clumps to small colonies. Flowering appears in July to August.
Full sun, average garden soil to loamy soil, medium to dry. Hardy in zones 5-8.
Native wildflower in lower Midwest, so to Iowa, Missouri, Arkansas, Illinois, Indiana, Ohio, Kentucky, Tennessee, West Virginia, Virginia, and South and North Carolina.
Very good pollinator plant - it atttracts many species of native bees (including some rare ones), bumblebees, pollinating flies, butterflies, skippers and moths.
This plant was reported both deer resistant and deer browsed, so it may differ in every region.
For naturalistic plantings, prairie landscaping, naturalizing, but also for flower beds in full sun - combine with Echinacea, Liatris, Rudbeckia, Silphium terebinthinaceum or Panicum virgatum.
