This herbaceous perennial is native to Europe and Russia. It is a hardy plant that is highly adaptable to lowland sites as well as gardens at altitude. It loves moisture and likes to clump, forming a lush mound that flowers in multiple upright reddish-purple racemes. Sow seed in early spring in a greenhouse or directly into a garden bed. Barely cover the seed, tamp well, and keep evenly moist until germination, which usually takes one to three weeks. Space plants two feet apart.
