A large pine that grows between 20 and 40 m (65 and 130 ft.) or more tall and has a sturdy, straight, thick-barked trunk to 1.2 m (4 ft.) in diameter. The crown is tall and conical or rounded, the long, pale blue-green, needle-like leaves can reach 22 cm (9 in.). Pinus jeffreyi grows in mountainous areas on dry, often poor soils, mostly between 2000 and 3100 m (6600 and 10200 ft.) from southwestern Oregon through eastern and southern California onto the Baja California peninsula. It is a nice ornamental and a good timber tree that adapts well to a range of conditions, is hardy to fire, drought and severe freezes, although, as a mountain tree, it does not appreciate hot, humid summer conditions or air pollution. Suitable for USDA plant hardiness zones 6 to 8. Seeds require cold stratification for 2 months after soaking and sowing.
