Pacific Yew
Taxus brevifolia
Slow-growing and easily overlooked in the shaded understory, Pacific yew became globally significant in the late 20th century when a compound in its bark, paclitaxel, was developed into one of the most important chemotherapy drugs ever discovered.
Where found
Shaded understory of moist conifer forests throughout the Cascades and Coast Range.
Fun facts
- Paclitaxel (Taxol), first isolated from its bark, remains a critical cancer chemotherapy drug.
- Nearly every part of the tree is toxic except the fleshy red aril around the seed.
- Its dense, strong wood was traditionally used for bows, paddles, and tool handles.
