About

Acacia salicina is a thornless species of Acacia native to Australia. It is a large shrub or small evergreen tree growing up to 13.7 m (45 ft) tall. It is a fast grower, dropping lots of leaf litter, with a life span of about 10–50 years. In its native range, A. salicina flowers from February to June. In the Northern Hemisphere, A. salicina flowers primarily from October to January and the seed pods are often visible from April to July. The tree's seeds are shiny, black and have a crimson appendage-like aril.

A. salicina is "closely related" to Acacia ligulata and Acacia bivenosa.

How to grow it

Acacia salicina is found throughout Australia, growing in regions receiving in excess of 1500mm annually in northern Queensland and as low as 100mm annually in central Australia. Its natural altitude range is from 50-300m above sea level. It does well in full sun exposure and tolerates frosts down to -6.7 deg. C (20 deg. F).

Uses

Erosion management: Acacia salicina can be used to help stabilize riverbanks and other areas.
