This name is getting quite common in Australia, where it is used due to the association of our national tree, the Golden Wattle, which is a member of the Acacia family. It is therefore considered a very patriotic name.It's become common enough that parents are now tacking another name on the end, like Acacia-Lily or Acacia-Rose, so their daughter doesn't get mixed up with other little Acacias in their class.Good choice for someone born on Wattle Day (September 1st).
