(Pinus monophylla)
The single-leaf pinyon pine is native to the southwest United States and produces a large edible nut with a thin shell. This tree prefers arid climates and a hot summer. It is unique in that this is the only species of pine that has one needle per fascicle. Overall, it is slow-growing but can live for many years, and makes an excellent specimen tree with pleasant blue-green foliage.
Germination: Place seeds into a pot and keep soil moist. Once germinated, water the trees once or twice a week depending on ambient temperature. Germination is slowed if temperature is too high however, over 24 degrees C.
Storage: Keep seed refrigerated for best seed preservation.
