This drought-tolerant perennial is noted for its vivid indigo flowers along deep purple-black stems, which gives it a bicolor appearance. It blooms in early summer and then sporadically if spent flowers are deadheaded. It forms an upright clump, with the flower spikes rising to 2 feet in height; its wrinkled, softly hairy leaves form a mound 1 foot high. Plants spread 1 or 2 feet wide. These are some of the showiest plants for containers and mixed borders. Butterflies love them.

'Goldrush' heralds the coming of fall with masses of tiny, yellow flowers for four weeks in August and September. Its compact size—about a foot tall—makes it a great candidate for a rock garden or border edge.
