Green Douglas Fir, Pseudotsuga Menziesii Viridis, Tree Seeds

Douglas Fir is a huge and stately long-lived evergreen conifer, the largest member of the pine family. Specimens more than 300 feet tall with trunk diameters exceeding 15 feet are known. Some of the larger trees are believed to be over a thousand years old. Douglas Fir has a narrow pyramidal shape, losing their lower branching and becoming more cylindrical with age.

The bark on young trees is smooth and ashy gray; that on mature trees is reddish brown and broken into longitudinal plates; really large trees can have bark more than 12 inches thick. The grayish green needles are flattened, quite soft, about 1 inch long, and arranged all around the twigs like a bottle brush. Needles are fragrant when bruised.

The cones are oval and pendulous, 2 to 4 inches long and each scale has a conspicuous three-pointed bract that gives the cone an overall spiny look. These trident shaped bracts are unique to the Douglas Firs. Douglas Firs start bearing cones at the tender age of 10 years and continue to produce nearly every year of their lives.
