Identification. Leaves (Needles): Slender, flexible, occurring in groups of three, bright green, 12-20 cm long. Cones: Orange or yellow male cones, occur in small clusters at the tips of branches; oval and woody female cones, 8-15 cm long; scales have sharp, rigid prickles.
Ponderosa pine's five subspecies, as classified by some botanists, can be identified by their characteristically bright-green needles (contrasting with blue-green needles that distinguish Jeffrey pine). The Pacific subspecies has the longest— 73⁄4 inches (19.8 centimetres)—and most flexible needles in plume-like fascicles of three.
Ponderosa pine (Pinus ponderosa) is one of the most widespread trees in the western United States. This distinctive pine can be found from the Black Hills of the Dakotas to the Cascades and from British Columbia to Southern California.
Ponderosa Pines are one of the most widely distributed pine species in North America. They dominate forests in the western United States and Canada, thriving in various climates from semi-arid to more moist regions, though they’re particularly known for their presence in the Rocky Mountains, the Sierra Nevada, and the Black Hills.
Ponderosa Pine Identification: Needles are 5 to 10 inches long and in bundles of three, forming tufts at the end of each branch. Cones are oval, 3 to 6 inches long and 2 to 4 inches in diameter, with outwardly curved spines that make them prickly to handle.
Ponderosa pine, the largest of the western pine species, is found on semi-arid plateaus and slopes in B.C.’s southern interior. The wood is straight-grained, nonporous with a fine and uniform texture, and light in colour, ranging from cream to yellow to pale reddish-brown.
There are 2 varieties: Pinus ponderosa var. arizonica in the southwest and the Rocky Mountain variety, Pinus ponderosa var. scopulorum, occurring east of the Continental Divide, in the Central Plateau of western Colorado, Utah, eastern Nevada, Arizona and New Mexico.
Ponderosa Pines are easily recognized by their tall, straight, thick trunks, clad in scaled, rusty-orange bark that has split into big plates. One can easily identify some trees by smelling their bark. Ponderosa Pine bark smells like vanilla or butterscotch.
Pinus ponderosa. Family: Pinaceae or Pine. Leaves: Needles in groups of 2 and 3; 3" to 10" long; yellow-green; less sharp-pointed than those of Austrian pine; somewhat twisted; evergreen, remain on tree 3-6 years. Twigs/buds: Twigs stout; orange-brown; smell like turpentine when crushed.
The ponderosa pine (Pinus ponderosa), also known as yellow pine, is one of the most widely distributed trees in the western United States. Named for its "ponderous" or heavy wood, ponderosa pines can be found in 16 different western states.
