Pea-type cream-yellow flowers form large, lush, cascading lupinesque spikes that bloom April to June, pollinated by bumblebees, digger bees, mason bees, butterflies, and moths. Notable seed pods develop in late summer. 1.5' T x 3' W, and doesn't like to be transplanted due to its long taproot. A native to midwestern U. S. prairies and dry, open woods, it would appreciate our NW oak savanna habitat or a low-maintenance section of your garden. Rare!
