Douglas Fir

doug fir tree

Douglas fir

Back to all 2014 trees

Scientific Name: Pseudotsuga menziesii

Under Power Lines:

Street Tree Planting:
Yes—but only on planting strips 12 feet or wider. If planting a street tree, you must be approved for a permit.

The classic Pacific Northwest native evergreen conifer. The Douglas fir is known for its noble, upright growth and lush needles, which form a beautiful downward sweeping canopy. The tree needs plenty of room to grow upward, making it an excellent yard tree.

Mature Height:
60 feet

Mature Spread:
15 feet

Short, deep green needles grow around all sides of the twigs for a fuzzy, full appearance.  Sticky, red buds at twig ends harbor pale green new growth and remain after buds burst.

Bright red new cones are upright, soft and frilly, ageing to pendulous brown cones.

Mature cones are a soft brown color and hang downward from branches, sporting three-pronged seeds protruding from scales.

Cultural Notes:
Prefers moist, rich and loamy soils and wet conditions. Will fail in dry or drought prone areas. Needs full to partial sun and plenty of room to grow.

Potential Problems:
Generally very resistant to disease; can be prone to Douglas fir bark beetles, cankers, leaf and twig blights.

Minimum Planting Distances:

  • 3 ½ feet back from the face of the curb
  • 5 feet from underground utility lines
  • 10 feet from power poles
  • 7 ½ feet from driveways (10 feet recommended)
  • 20 feet from street lights and other existing trees
  • 30 feet from street intersections
