Last updated

Pacific yew is a native conifer of western North America, ranging from southeastern Alaska to northern California. It is a slow-growing tree reaching 40 ft with gray-green foliage, brown fruit, and a fine-textured, single-stem form. The bark is thin and dark red-purple.

Pacific yew prefers partial shade with adaptable, moist soil and tolerates a pH of 6.2-7.5. Hardy in zones 5a-8b, it requires high moisture and performs best in deep forests. It develops long taproots and is notably slow-growing. All parts except the fleshy fruit are toxic.
