Thanks for your thoughts, David.
Yes, the wattle tree is an Australian native.
It was exported to a few other countries many years ago, as the bark contained tannin; used to tan leather.
There are a few varieties: Silver wattle, golden wattle, black wattle and a miniature version that has creamy white flowers.
Black wattle is named for the colour of its bark, but has yellow flowers. That one spreads lots of seeds and is considered a pest by landholders.
Generally, though, they are all beautiful in Spring, and inspired the well known Australian sports colours of green and gold.
They are very prolific in this region and many parts of Australia, and there are lots of them starting to bloom around the property at the moment.
