Trillium ovatum, or western trillium is one of the first spring flowers we see in the forested lands west of the Cascades, Trillium is a true jewel. It typically grows to a height of about 12 to 18 inches and produces beautiful, showy white petals. This is a clump-forming western native perennial, similar to Trillium grandiflorum, but with narrower leaves. The red-green stems are stalk less, and dark green leaves appear in triads.
Flowers are musk-scented and pure white fading to pink; they are composed of three opposing petals. This plant establishes rhizomes in shady locations where soil is rich and moist.
When choosing trilliums be aware that some plants are protected under law and should not be dug from state or federal lands. At least one species, Trillium persistens, is listed as endangered by the federal government. Ovatum is widely available through commercial nurseries.

No serious insect or disease problems.
Trilliums are easily propagated by division. Plants can be grown from seed, but it can take up to two years for fresh seed to germinate and another five to seven years for plants to bloom.
A classic spring-blooming, woodland wildflower. Excellent when massed in a shaded woodland garden, naturalized area or wildflower garden. Mixes well with other spring wildflowers and ferns. I would not recommend this plant for a perennial border.
