Acacia calamifolia, commonly known as Reed-Leaf Wattle, is an evergreen shrub or small tree native to the mallee regions and open woodlands of Southern Australia. It exhibits a rounded habit, typically reaching a height of 2 to 4 meters (7 to 13 ft) and a similar width, although some individuals may grow as tall as 10 meters (33 ft). The Reed-Leaf Wattle blooms between October and November, producing inflorescences on two to eight-headed racemes. Its flower-heads are spherical to obloid in shape and contain 28 to 46 golden pale yellow to golden flowers, which are quite showy and attract pollinators.

This species is valued for its ornamental qualities, including its vibrant yellow flowers and its ability to provide low shelter, making it a suitable choice for medium-sized ornamental plantings. It is drought and frost tolerant, surviving temperatures down to −7 °C (19 °F), and can provide a good habitat for birds. Reed-Leaf Wattle is adaptable to full sun or part shade and prefers well-drained soils but can withstand short periods of waterlogging. It is used in gardens for its ease of maintenance and ability to thrive with low or medium water requirements. Potential problems include susceptibility to pests such as aphids and borers, and diseases like root rot in poorly drained soils.CC BY-SA 4.0
