Pinus coulteri D. Don
Pinaceae (Pine Family)
Synonym(s): Pinus ponderosa ssp. coulteri
USDA Symbol: PICO3
A 30-70 ft., conifer with a broad pyramidal or sometimes asymmetrical crown. The long, stiff, deep-green needles are up to 12 in. in length. Huge cones remain on the tree for several years. Straight-trunked tree with rows of nearly horizontal branches formed annually, an open, thin, irregular crown, and very large, heavy cones.
This pine has the heaviest cones of all pines in the world, often weighing 4-5 pounds (1.8-2.3 kilos). The lightweight, soft wood serves for rough lumber and fuel. Indians once gathered and ate the large seeds; now squirrels and other wildlife consume the annual crop. It was discovered in 1831 by Thomas Coulter (1793-1843), the Irish botanist and physician, who collected plants in Mexico and California.
