Trillium Species, American Wood Lily, Pacific Trillium, Western Trillium, Western Wakerobin

I have hundreds (maybe a few thousand) Trillium ovatum now in flower in natural habitat at my home in Gig Harbor, WA, nearing peak flower...Read Moreing on April 1, 2011. This Trillium seems to grow equally well in swamps on deep muck saturated to the surface almost year round (under mostly deciduous trees) and in well-drained, moist, mostly shady, coniferous forests. There is very little of it in the dense shade of Thuja plicata stands, at least on my property.

Trillium ovatum: Western native. Resembles T. grandiflorum but has narrower petals; flowers are usually upright and are borne on stalks.
