Shoestring acacia develops into a medium size evergreen tree with an upright habit, 20-40 ft. tall, 15-25 ft. wide. It produces very long and narrow pale green phyllodes, 12-16 in. long, that hang from weeping branches. Light yellow flowers occur in winter and early spring, and are followed by 10-12 in. long bean-type pods in the summer.
This tree is native to warm and dry interior regions of Australia where it grows in light or heavy soils and even in those with some alkalinity and salinity. Natural rainfall is limited to 15-20 in. per year; some areas experience short periods of frost. When planted in the Inland Empire, it grows well with low to moderate amounts of supplemental water; more water results in faster and larger growth. As a young tree, this species has a tall and open habit, but becomes broader and more dense as it matures. Its long phyllodes hang in a graceful manner and produce a weeping appearance.
