limber pine Pinaceae Pinus flexilis James Listen to the Latin symbol: PIFL2 Other Fact Sheets
Leaf: Evergreen needles, 2 1/2 to 4 inches long, fascicles of 5, dark green and rigid with lengthwise rows of stomatal bloom. Remain on tree for 5 to 6 years.
Flower: Species is monoecious; male cones are small and reddish; female cones are bright reddish-purple.
Fruit: Moderate sized woody cone (3 to 6 inches long) with a short stalk. Imbricate scales are thick, blunt, slightly reflexed, and unarmed. Cones turn from green to brown as they ripen and scales open to release their seeds (unlike whitebark pine). Seeds are large and usually wingless.
Twig: Stout but very flexible (can be tied into knots), silvery-white to gray, droop with age, but tips often turn up.
Bark: Initially thin, smooth and gray-white; later it darkens to brown or black with deep fissures and square plates.
Form: Typically small (30 to 50 feet tall and 1 to 3 feet in diameter) and contorted by the wind and harsh growing conditions. Often has multiple, plume-like tops with drooping branches.
