Douglas Fir   (Pseudotsuga menziesii ssp. menziesii) Douglas-fir Picture

General: 70 m tall (sometimes 80-90 m)

Leaves: Spirally arranged flat needles, 2-3 cm long with pointed tips. One groove on top of needles, two white bands of stomata on lower side.

Cones: Small reddish brown pollen cones; oval hanging seed cones. Changing green to reddish brown, three prominent forked bracts extend from scales.

Ecology:  Dry to moist sites.

Propagation:
Seed: Seeds mature August to early September. Collect the cones at this time when they appear brownish or purplish. The ideal collection time lasts only 2-3 weeks.  Dry the cones in well ventilated conditions where they can be stored for 3 to 4 months.  Open the cones by air drying in warm weather then heating in a kiln 35-40 for 1-2 days. Separate the seeds from the cone by shaking the dried cones.  Screen out the seeds and de-wing them. They may be stored at 6-9 moisture content, -5 to 0ºC for up to 20 years. Sow the seed in the fall to allow to stratify naturally over the winter or so in spring after 30-40 days stratification at 0-4ºC.

Propagation:
Seed: Fruit matures July - September when berries turn red.  Clean seeds by macerating in water to float off pulp.  Seeds do not need to be dried if they are to be used immediately.  If they are to be used within weeks or months of collection, the seeds only need to be surface dried.  For longer storage, dry for a longer period of time and store at 1-5ºC in sealed containers.  If sowing in the spring, seeds should be cold stratified at 5ºC for 90-126 days in a sand and peat mix before sowing.  If sowing in the fall, sow early enough to allow the seed embryo a period of after ripening before the ground freezes.  Outplant seedlings at 1-2 yrs.
