Northwest Conifers

Spruces – Picea

The Spruces are easy to identify. The needles look like Douglas Fir needles, but they are pointed and sharp. Unlike Douglas Fir and the true firs, each spruce needle grows on a small peg. These unique pegs remain even after a branch loses its needles. The cones have paper-thin scales. The bark is gray and breaks into scales on large trees. Picea is derived from the Latin for "pitch."  Three species of spruce grow in the Northwest.
