Picea, Pseudotsuga and Abies
Picea, Pseudotsuga and Abies all share
the common characteristics of being evergreen, cone-bearing
trees with needle-like foliage. They are typically better
suited for cool climates such as in the northeast and northwest
regions of North America. These plants can survive, but typically
do not perform especially well in the South or Midwest.
Picea
The genus Picea is a group of trees and shrubs commonly
referred to as Spruce. One of the key identifying characteristics
are the peg-like stalks which attach the leaf to the stem.
Cones are pendulous, and the needles are generally 4-sided
with a very sharp point.
Pseudotsuga
The genus Pseudotsuga is a species commonly known
as Douglasfir. The needles are flat, somewhat arranged on
a horizontal plane with needles branching out in a V-shaped
arrangement. Cones are pendulous with 3-pronged bracts that
fan out.
Abies
The genus Abies is a group of trees and shrubs commonly
referred to as Fir. Unlike, the Spruce and Douglasfir, Fir
trees' cones stand upright on the stem and the needles are
flat with a relatively dull point.
