Thermopsis villosa 9a held above the foliage in(aka: Thermopsis caroliniana) Thermopsis villosa is a North American (Maine south to Alabama) native baptisia cousin, that's lived in the shadow of its more popular relative. Thermopsis villosa jumps out of the ground in mid spring, developing 4' tall, upright, un branched spikes, each terminating in clusters of butter yellow flowers. Rich green foliage adorns this drought tolerant, easy to grow, clumping, sun loving native perennial.
