The golden wattle, Acacia pycnantha, is Australia's national flower.
You'll find the golden wattle growing in the wild in many parts of Australia, such as in South Australia's Eyre Peninsula, western Victoria and southern inland areas of New South Wales.
Mature golden wattle plants are said to be reasonably frost and drought tolerant. The specimen shown above was planted in the Royal Botanic Gardens Sydney in 1987.
Because native golden wattle grew naturally in the Australian Capital Territory and had other desirable features including design potential, it enjoyed popular acceptance as Australia's national flower. It was proclaimed Australia's national flower in 1988, the year of Australia's bicentenary.
