Pinus contorta
An evergreen conifer native to western North America with a twisted trunk and needles in bundles of two, highly tolerant of wind and salt spray, with fire-driven regeneration and serotinous cones in some subspecies, ranging from shrub to tall across coastal to inland habitats.
Common Names
Lodgepole Pine, Shore Pine, Beach Pine, Sierra Lodgepole Pine, Tamarack Pine, Coast Pine, Rocky Mountain Lodgepole Pine, Bolander Pine, Black Pine
Summary
Lodgepole pine is a western North American evergreen native from Alaska and the Yukon to Baja California and east to the Black Hills, with coastal shore pine and inland lodgepole forms. It grows as a medium- to large-sized tree with a twisted, contorted trunk and a broad crown; needles occur in bundles of two and are 1.5–3 inches long, cones are egg-shaped and small, and bark is thin and scaly; cones may open at maturity or remain closed for years, reflecting variation in serotiny.
For cultivation, it tolerates full sun and a wide range of soils, including poor or dry sites, and regeneration is prolific after-fire events; propagation is by seed from cones, with seeds maturing in September–October and germinating in roughly 30–50 days, and stored seeds viable for up to 17 years; uses include timber, posts, landscaping, windbreaks, and habitat for wildlife.
