Pacific Rhododendron
Rhododendron macrophyllum

Washington's state flower, a stately wild rhododendron lighting the conifer understory with big trusses of rose-pink bells in late spring. Wants acidic, well-drained woodland soil. The leaves are poisonous and the pollen probably so; ingestion can bring on convulsions.
