Blackbrush acacia is a semi-evergreen tree that grows slowly to 15 feet tall and wide. The small compound leaves are glossy and dark green. The bark is light gray with extremely thorny branches. Clear yellow, fragrant, rod-shaped flowers provide quite a show in the spring. It is heat and wind tolerant, and requires little additional moisture even in the low deserts. Surprisingly, it will perform well as a lawn tree. It is not picky about soil types but prefers good drainage. Plant in full sun and reflected heat locations. Blackbrush acacia grows on limestone hills in south and east Texas, at elevations between 1100 and 1800'.
