P. edulis is a short and scrubby tree that rarely reaches heights taller than 35 feet. Growth is very slow and trees with with diameters of 4 to 6 inches can be several hundred years old. It typically grows either in pure stands or with juniper. The chunky little cones produce a well-know and tasty nut. The wood is very fragrant when burned.
