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.
