Border pinyon, scientifically known as Pinus discolor, is a coniferous tree native to the arid regions of Arizona and northern Mexico, with naturalized populations in Europe as well. This tree thrives in full sun and prefers dry to moist conditions, growing best in light or sandy soil. It can reach heights of 15 meters and is hardy from zone 7 to 10. Known for its edible seeds, border pinyon is a valuable resource for wildlife and humans alike. One distinctive feature sets it apart: its needles grow in pairs, while another unique characteristic is the bark, which has a reddish-brown hue and peels away easily.
