Bulbs and bulblike plants
Bloom in early spring; need some winter chill. Each stem is topped with a whorl of three leaves; a single three-petaled flower appears in the center of the whorl (sometimes on a stalk, sometimes virtually stalkless). Plant in a shady, woodsy site. Left undisturbed, plants will gradually increase by rhizomes. Dies to the ground in mid- to late summer. Specialists in native plants offer many species.Trillium ovatum
