Foxtail pine is broken into two subspecies: Pinus balfouriana subsp. austrina R.J. & J.D. Mastrogiuseppe, which is the Southern Foxtail Pine and Pinus balfouriana subsp. balfouriana, which is the Northern Foxtail Pine. The two subspecies have probably been separated since major geological disturbances early in the Pleistocene epoch.
The champion Foxtail Pine in the Trinity National Forest is 76 feet tall, but the typical height is between 20-50 feet and 1-2 feet in diameter. It is a

accounts state 20 years. Up curved at the tips, the needles are stiff, prickly tipped and may have a waxy substance on the inner surface. Male cones are vivid yellow, as seen in the image to the left. Females are purplish-brown to reddish-brown. They are 3-5 inches long and the scales are tipped with a small curved prickle. Seeds of the Foxtail Pine are pale brown, spotted with red, and are single-winged. The structure of the tree depends on site specifics. In open areas such as rocky out croppings and ridges, it is often found with a Krummhulz form, meaning twisted and deformed by winds. Where protected from high winds, it forms a broad conical to irregular crown.
slow growing tree. The reddish-brown bark is furrowed and vertically ridged. Twigs are red-brown when young, turning yellowish-gray when mature. It's needles are short, only 1-2 inches long, and are densely clustered in bundles of 5, giving the species its distinct foxtail-like appearance. They persist on the tree for 10-12 years, although some
It's preferred habitat is on poor rocky soils that are dry, well-draining and usually exposed. Pinus balfouriana

is typically found at higher elevations on sandy to gravelly soils on out croppings, ridges and cliffs. Best growth is attained on fast draining, infertile, sandy soils.
Foxtail Pine is a rare tree, but it is cultivated as an ornamental landscape tree. It also helps control soil erosion and is valuable in watershed management.
