Clump-forming, spreading, rhizomatous perennial with strap-shaped, curving, leathery almost black leaves. Short bell-shaped, racemes of pale purplish flowers in spring, followed by dark blue-black fruit.

Looks good interplanted with small wandering perennial, lacy foliage and fragile pink flowers. It also makes a good foil for dwarf rock garden bulbs in spring.
