Bailey acacia grows best in light, well-drained, fertile soil. Acacia is an attractive low water use shrub or small tree, which has a showy spring flowering quality, as well as its distinctive, evergreen, feathery foliage. Its roots may be invasive in residential garden settings, but is effective as a soil stabilizer. It may require regularly scheduled light top-trimming (but not necessarily shearing) of vigorous top shoots to maintain its height below 25'.
