Cardamine angustata (syn. Dentaria heterophylla) is an eastern North American mustard relative with compound leaves comprised of three broad, toothed leaflets emerging from the rhizome in late winter and going dormant by early summer. Makes a useful hellebore companion. In spring the plants produce clusters of small, white to pink, four-petaled flowers popular with bees and butterflies on stems with linear stem leaves.
