Weeping Acacia

Acacia floribunda is a spreading shrub or tree that typically grows to a height of 2–8 m (6 ft 7 in – 26 ft 3 in) and has smooth grey bark, sometimes becoming rough, and pendulous branches often covered with soft hairs. Its phyllodes are linear to narrowly lance-shaped, 50–190 mm (2.0–7.5 in) long, 1.5–12 mm (0.059–0.472 in) wide, thin and pliable with up to three main veins. The flowers are borne in one or two loosely packed spikes 20–80 mm (0.79–3.15 in) long on a very short peduncle. Flowering usually occurs from June to September and the pods are more or less cylindrical, mostly straight to strongly curved, 60–120 mm (2.4–4.7 in) long, 2–4 mm (0.079–0.157 in) wide, firmly papery and more or less constricted between the seeds. The seeds are elliptic, 3–5 mm (0.12–0.20 in) long and glossy brown with a small aril.

White sally wattle is widespread in forests and woodland from Stanthorpe, Mount Barney and Tambourine Mountain in south-eastern Queensland through New South Wales to Briagolong in eastern Victoria with an isolated occurrence at Nambour. It mainly grows in coastal sclerophyll communities, often in sandy soil, and is common along the banks of streams. It is naturalised in other places in Victoria and Tasmania and possibly the Australian Capital Territory.

The phyllodes, twigs and bark of this species contains the compound NN-Dimethyltryptamine (DMT) (0.4-0.5%) and other substituted tryptamines.

In landscaping, Acacia floribunda is very useful for controlling erosion, especially in gullies. It is also useful as a hedge or screen plant. It can be propagated from scarified seed or treatment with boiling water.
