Rocky Mountain Lodgepole Pine

You will encounter this inland variety in the dry, cooler mountain valleys of eastern Oregon and Washington, where it often forms nearly pure stands of tight columnar form. Rocky Mountain lodgepole is much taller than its coastal cousin, reaching 110 feet in ideal conditions with a narrow, columnar crown. Its reddish-brown bark distinguishes it from shore pine, and its needles, though paired, are wider and less twisted than the coastal form.

This tree thrives in cooler mountain sites with moderate precipitation (20-35 inches) and well-drained soils, extending hardiness south to Arizona and California. In the Puget Sound lowlands, it rarely performs well and struggles with root rot in heavy soils; reserve it for eastern Washington or high elevation sites. White pine blister rust and lodgepole needle miner are persistent threats; expect eventual height to exceed 100 feet if conditions favor it, though growth slows dramatically in marginal sites.
