Rate of Growth for a Willow Acacia


The willow acacia tree is native to Australia and the scientific name for the plant is Acacia salicina. The tree is not a true willow, according to the United States Department of Agriculture, but a member of the pea family. The tree is also referred to as the Australian willow.


The willow acacia tree can reach up to 40 feet in height and have a canopy about half the width of the height. The tree grows roughly at the rate of 25 inches per year, according to the Urban Forestry Program in Tucson, Arizona.


The willow acacia grows quickly and has thin branches that arch up and hang down like a willow. The leaves are small and can range in color from gray to green or blue-green. According to the University of Arizona Cooperative, the tree is a smooth-barked tree until it matures and develops fissures. Between late summer and early winter, the tree produces tiny clusters of puff balls that are creamy white to yellow flowers.


The willow acacia grows best when planted in full sun and in soil that drains well. The tree can be planted in numerous types of soil and is drought tolerant according to Florabank.


Originating in Australia, the willow acacia can now be found in many regions throughout the world. The plant can tolerate cold temperatures as low as 20 degrees Fahrenheit.


To keep the canopy of the willow acacia thinned, the tree can be pruned occasionally. The tree is basically self-sufficient and requires little maintenance over the years unless it is struck by disease.
