This stalwart perennial has deep blue-violet very long spikes, and a strong secondary flush of blooms that will bring yet another flush of butterflies. As with all Baptisia give them lean soil and don't spoil them too much. Clay or shallow, rocky soil is okay. Baptisias dislike being moved because of their long, tap-root-based roots. 4' x 4' Ships when dormant.
Minimum temperature: -20° F
