The single-leaf piñon (or pinyon) is an aromatic pine tree with short, stiff needles and gnarled branches that grows in coarse, rocky soils and rock crevices. Normal height for this tree is about 15 feet, but the single-leaf piñon can grow as high as 50 feet under ideal conditions.
Native Americans traditionally harvested piñon tree nuts as a family, picking the ripe nuts that fell to the ground (to be roasted or eaten raw).
