Australian Native Plants Society (Australia) - ANPSA The Acacia Page
The golden wattle, Acacia pycnantha, is Australia's floral emblem. But it is just one over over 1200 species of Acacia which can be found in all Australian states and even overseas.
Thanks to Bruce Clark for providing comments and suggestions and to Gary Orr for information on short duration boiling water treatment in germination of Acacia species.
