Ponderosa pine is native to western North America.

Needles occur in groups of 2-5, with three most common. Each needle is 2½-10" (7-25 cm) × ¹/₃₂" (1.5 mm), deep yellow-green, and slightly twisted. Cones are about 4½" (11 cm) long, oval to cylindrical when immature, maturing to be more egg-shaped.
