In north Florida, zone 9a, this plant has performed poorly and/or died for me in three different locations. Acacias, Jerusalem thorns and desert willows are growing well in at least one of these sites.

Honey mesquite is a common shrub of the Mojave and Colorado deserts. It is a plant with a very deep root system (up to 150') that can extract water from the water table. It often grows in dense thickets near desert washes, but also occurs at the base of sand dunes and other areas where the water table is not far below the surface. Honey mesquite has long, flattened pods and elongate clusters of tiny white flowers. The large seeds are edible and are staples in the diets of desert animals.
