The pinyon pine is a signature tree of the inland west. It is an slow-growing pine for arid regions. In the wild it grows in the dry mountains of the southwestern United States. Its pine nuts are edible and were an important food source for indigenous tribe's people. These are the pine nuts of culinary commerce.
The pinyon has a symmetrical habit in its youth but becomes more rounded with age. Its needles are in twos, dark green in color and highly fragrant. It bears beautiful small, round, nut-filled cones that are decorative and highly valuable to wildlife.
This is an ideal pine for landscaping due to its small size and toughness. It performs very well in containers and can be trained into an attractive bonsai specimen. Its drought resistance exceeds that of the taller mountain pines, so plant it in high desert landscapes or extremely dry regions. It will do best in well-drained soils with marginal fertility. It is compatible with western sagebrush and yucca plant communities. Consider this a quintessential ranch tree that is non-toxic to livestock and requires no water once established.

|Germination||1. Place the seeds in a container with tepid water and soak them for 24 hours. Change the water and wait another 24 hours.|
2. Put the seeds in a small plastic bag and cover with damp sand. Place the bag holding the seeds in the refrigerator for one to two months to stratify the seeds, which is preserving seeds in layers of moisture-laden peat, soil or sand. Check the sand and water as needed to maintain moisture. Don't allow the seeds to get soaked.
3. Fill small pots with compost. Place one or two pine seeds on top of the compost in each pot, then cover the seeds with a thin layer of sand.
4. Water the sand and compost to add moisture, then place the pots in a warm, sunny location. As the seedlings emerge and grow, the soil needs to remain moist, not wet.
5. Repot the pine trees into medium-sized pots in the fall. Grow them in the pots for the following season until they are large and strong enough for transplanting into the landscape.
