Picea sitchensis, the Sitka spruce, is a large, coniferous, evergreen tree growing to just over 100 meters (330 ft) tall,[2] with a trunk diameter at breast height that can exceed 5 m (16 ft). It is by far the largest species of spruce and the fifth-largest conifer in the world (behind giant sequoia, coast redwood, kauri, and western red cedar),[3] and the third-tallest conifer species (after coast redwood and Himalayan cypress). The Sitka spruce is one of only four species documented to exceed 100 m (300 ft) in height.[2] Its name is derived from the community of Sitka in southeast Alaska, where it is prevalent. Its range hugs the western coast of Canada and the US and continues south into northern California.
