The leaves are needle-like, paired and often twisted, and 3-7 cm long. The 3-7 cm cones often need exposure to high temperatures (such as from forest fires) in order to open and release their seeds, though in subsp. "murrayana" they open as soon as they are mature. The cones have prickles on the scales.It is occasionally known under several English names: Black Pine, Scrub Pine, and Coast Pine. The species name "contorta" arises from the twisted, bent pines found in the coastal area.
Lodgepole Pine is the Provincial tree of
Alberta, Canada. Lodgepole Pine will hybridise with the closely related Jack Pine.
