Velvet Mesquite
Prosopis velutina is a deciduous native tree that takes full sun, alkaline soil and limited rainfall. Growing 25 feet tall and wide, it creates a pleasant shady canopy and its seedpods can be ground into a nutritious flour, once a common food source for Native Americans. This tree species has thorns, so site it where that's not an issue. Be careful not to overwater mesquite trees, which encourages abundant, top-heavy foliage growth before the root system can develop to anchor the weight. Top-heavy mesquites are susceptible to blowing over in strong winds!
