Acacias, commonly known as wattles, are a unique part of our Australian identity. The green and gold colours are used to represent the nation in sport and Acacia pycnantha is Australia's floral emblem. With over 900 species in the genus Acacia in Australia, they are found throughout the country.
Many acacias flower in winter and spring, bringing a burst of golden colour and brightness to the garden. However, at any time of the year, some species will be in flower. The tiny flowers, which can range in colour from pale cream to deep gold, can be gathered in balls, or rod-like spikes. Wattle Day is celebrated on 1 September each year.
An unusual feature of many acacias is the flattened leaf-like structure (which is actually a modified stem) called a phyllode which evolved to reduce evaporation.
As garden plants, acacias have an undeserved reputation for causing allergies. However, very few people are allergic to wattle pollen which is sticky and carried by insects, not by wind.
The Acacia garden has picnic tables and BBQs.
