Mexican Pinyon Pine

Mexican pinyon (Pinus cembroides) is a compact evergreen pine with stiff, bluish-gray needles and a rounded crown. It is characteristic of semiarid woodlands across the southwestern United States and Mexico, where it grows on varied slopes, ridges and foothills. [The University of Arizona Campus Arboretum](https://arboretum.arizona.edu/pinus-cembroides-pinyon-pine) describes the species’ form and the food value of its seeds; [the USDA Forest Service](https://research.fs.usda.gov/feis/species-reviews/pincem) documents its broad range of soils and sites. ## Site and landscape use Allow space for a small to medium tree with a rounded, spreading crown. Its native settings are semiarid, but local elevation, rainfall and soil conditions influence its growth. The species occurs on shallow, rocky or eroded slopes as well as deeper soils, so avoid assuming that one soil texture suits every site. ## Water and wildlife Provide reliable moisture during the first dry seasons while roots establish. The seeds are edible pine nuts and also provide food for birds and other wildlife. Although mature trees are adapted to semiarid habitats, new plantings need reliable moisture through their first dry seasons. ## Maintenance Preserve the natural crown and avoid unnecessary pruning. Remove broken or dead branches when needed, and protect young trees from severe drying while they establish.
