New Mexico State Tree

Pinyon

(Pinaceae Pinus edulis)

Adopted on March 16, 1949.

When the New Mexico Federation of Women's Clubs was asked to select a state tree, the pinyon, Pinaceae Pinus edulis, was their choice. It was adopted on March 16, 1949, the same day the roadrunner was adopted as the state bird. Ten years later, Nevada adopted the single-leaf pinyon.

Description of the New Mexico State Tree

Pinyon (Pinus edulis) is a small, drought-hardy, long-lived tree widespread in the southwestern United States. Its common name is derived from the Spanish piñon which refers to the large seed of pino (pine). For this reason the tree is known in the Southwest and throughout its range by this Spanish equivalent (49). Other common names are Colorado pinyon, nut pine, two-needle pinyon, and two-leaf pinyon (50). Its heavy, yellow wood is used primarily for fuel. Because of their delicate flavor its seeds are in much demand, making them its most valuable product.
