Overview
Pinyon Pine is a small, drought-adapted evergreen found in the foothills and lower elevations of Colorado. It produces large, edible pine nuts that have been an important food source for Native Americans for thousands of years. Pinyon typically grows with Utah Juniper in the pinyon-juniper woodland ecosystem.

Care & Maintenance
Extremely drought tolerant; overwatering can cause problems including root diseases. Avoid supplemental irrigation once established except during severe, extended drought. Plant in full sun with excellent drainage. Rocky or gravelly soils are ideal. Stressed trees are highly susceptible to ips beetles. Do not fertilize. Pinyon is very low-maintenance when sited properly.
