Prairie acacia is a tough subshrub found in dry soils on prairie hillsides, savannahs, rock outcrops, grasslands and open shrubby vegetation areas. It grows on well-drained acidic to slightly alkaline soils. This drought tolerant perennial subshrub grows from Zones 6a-10b of the USDA Plant Hardiness Zones Map.
