The Colorado piñon, or nut pine, is a small ornamental tree with inch-long needles in twos and stocky cones about 2 inches high. The edible seeds are harvested in the wild for sale. There was a specimen at 525 Los Arboles Avenue, visible from Searsville Road, partly obscured behind a fence, but it was absent in 2019.
Pinus monopylla, the singleleaf pinyon pine, extends throughout the Great Basin and into Eastern California. P. quadrifolia (Parry pinyon pine) and P. edulis have limited distribution in Southern California, and there is dabate over the taxonomic status of those populations.
Name derivation: Pinus – Latin for pine; edulis – edible (the seeds).
