Shore Pine

Pinus contorta ‘Contorta’

Under Power Lines:
No

Street Tree Planting:
Yes—but only in planting strips 10 feet or wider. If planting a street tree, you must be approved for a permit.

Description:
A short, uniquely shaped native conifer that makes an excellent yard tree.  A highly adaptable tree that thrives in poor soils, rocky sites, and even in boggy conditions. It’s twisting, “contorted”, trunk, branches and needles provide year-round interest.

Mature Height:
50 feet

Mature Spread:
30 feet

Leaves:
Dark green, twisting, evergreen needles in pairs on short shoots. Produces a dense “irregular” canopy.

Flowers:
Inconspicuous tiny yellow-green flowers.

Fruit:
Many small cones, which often remain on the tree. Seeds from cone scales.

Cultural Notes:
Extremely adaptable Pacific Northwest native. Will grow on infertile, even rocky or boggy, soils and can be wet or dry. In good, well-drained soil the habit tends to be upright but short. In poor and inhospitable soils the tree grows into its characteristic, twisting form. Prefers partial to full sun.

Potential Problems:
A hardy and disease resistant species. Potentially susceptible to common pine disease such as needle rust, blight and others.

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
