Design IdeasFew trees can rival this Mesquite for its light filtered shade. A great native of the Southwest that should be planted as groves to render patios and porches less vulnerable to oppressive heat. Plant in natural groupings for best results, or as a single specimen for front yard or beside a back patio. Keep away from pools because litter is a problem. The perfect tree for Santa Fe-style or drought-resistant gardens with a decidedly tropical flare. Particularly well adapted to Western native landscapes.

Key FeatureDrought Tolerant Specimen Tree

Thrives in lean, fast-draining soils. Water deeply, regularly during the first growing season to establish an extensive root system. Once established, water only occasionally, as needed to encourage vigor; over-watering causes structurally weak wood. Fertilize lightly when new growth begins in spring.
