Acacia rigens grows throughout much of Australia from southern Western Australia through South Australia, Victoria, New South Wales and Queensland. The name for the genus comes either from the Greek word "akazo" meaning "to sharpen" or from the Egyptian word "akakia", a name given to the Egyptian Thorn, Acacia arabica. The specific epithet is from the Latin word meaning "stiff", "rigid" or "unbending" and thought to be a reference to the rigidity of the phyllodes. Other common names include Needle Wattle and Needlebush Acacia. We thank Jo O'Connell of Australian Native Plant Nursery for introducing us to this wonderful plant and for the picture of it in flower. 

This information about Acacia rigens displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
