Western Trillium | Trillium ovatum
Elegant, white three-petaled flowers that fade to reddish purple. Some color morphs are deep red to magenta. Plants take 4-7 years to bloom, but the showy flowers are worth the wait! Also known as "Wake Robin" due to its unofficial designation as the harbinger of spring. They usually do well in shaded to partly shaded, moist woodland gardens, or even just moist (but well drained) areas on the north or east side of houses.
Western trillium (T. ovatum) is distinguished from white trillium (T. albidum) based on presence of mottling and whether the flower is on a stalk or sessile. Western trillium leaves are not mottled and the flowers are stalked, whereas white trillium leaves are mottled and the flowers are sessile.
