Wattles are easily recognized by their fluffy yellow flowers, and the Golden Wattle Acacia pycnantha the is the national floral emblem of Australia.

There are almost 1000 Australian species of wattle - or Acacia - and they are widespread and numerous. At any one time of the year, somewhere in Australia, there will be a species of wattle in flower. They occur in most habitats in Australia and are also found in the sub-humid and arid regions of Africa, India, and America.

Wattle wood has been used for building, furniture, tanning, tools, and weapons, and its seeds for medicine and food. Wattles stabilise and improve the condition of soils by adding nitrogen (converted from the air by a fungus living in their roots)

This here's the wattle
The emblem of our land
You can stick it in a bottle
Or you can hold it in your hand
