Sitka Spruce

Picea sitchensis. Large tree, 40 to 90 feet where planted, zones 6 to 9; full sun, part shade or shade; average or wet ground.

We do not grow Sitka spruce, and it is not in our shop. This page gathers what our tools say about it and the natives we grow for the same ground.

First crop15 to 40 years (stands from 20 to 40)
PollinationOne bears; a second improves the crop. Each tree carries both male and female cones and the wind carries the pollen; in spruces, seed from a tree's own pollen is more often empty, so trees in a group set more good seed.
LifespanCan live 800 years, and the oldest dated one reached 593. Only a tiny share of trees has ever been ring-counted or cross-dated.
