The golden wattle (Acacia pycnantha) was proclaimed as Australia’s national floral emblem in 1988, the year of the Australian bicentenary. It has been used in the design of Australian stamps and many awards in our honours system. A single wattle flower is the emblem of the Order of Australia. National Wattle Day is celebrated on the 1st of September each year. In recent times, the golden wattle has been used as a symbol of remembrance and reflection. On national days of mourning, for example, Australians are invited to wear a sprig of wattle.
