|Will the thornless chilean mesquite grow in Claremont Ca. I think it's zone 19. Remy.|
|Thornless Chilean Mesquite is not recommended for your gardening region. It thrives in Sunset zones 10-13 and 27-30, and your region is 19. Although it is hardy to 15F, which is lower than your lowest temperature, it needs a longer summer than your region can provide.
