Trillium ovatum

Landscaping Value: The elegant, nodding flowers of this native plant, herald in spring for many woodland garden lovers. The large flowers combine nicely with ferns and azaleas to add a feeling of lushness to the forest floor. Collecting is depleting wild populations, so please buy seedling grown specimens from a reputable nursery. 

Alternate species and cultivars:  Trillium grandiflorum, Trillium kurabayashii, Trillium rivale are other western North American species.
