Acacia pycnantha is Australia's official floral emblem, and the reason is obvious in late winter when the tree disappears under masses of large fragrant golden ball flowers. It is the wattle behind Wattle Day and the green and gold of national sporting colours.
The Golden Wattle grows very fast at 1 to 2 metres per year, reaching 4 to 8 metres tall and 3 to 6 metres wide with an open spreading habit and broad sickle-shaped foliage. It is used for quick screening, rural shelter, revegetation and as a fast feature tree while slower species establish.
This Australian native tolerates light to moderate frost once established, along with poor sandy soils and extended dry. It grows in full sun and, like most fast wattles, is relatively short-lived at 15 to 20 years.
Frequently Asked Questions
About Acacia pycnantha
Is Acacia pycnantha Australia's floral emblem?
Yes. Acacia pycnantha was formally proclaimed Australia's national floral emblem in 1988, and its flowering is marked by National Wattle Day on 1 September.
How big does the Golden Wattle grow?
It reaches 4 to 8 metres tall and 3 to 6 metres wide with an open spreading habit. It is a small to medium tree suited to most gardens and rural properties.
How fast does Acacia pycnantha grow?
Very fast, at 1 to 2 metres per year in good conditions. It delivers a usable screen or feature tree within two years of planting.
When does the Golden Wattle flower?
Masses of large fragrant golden ball flowers appear through late winter and early spring, typically August and September, which is why Wattle Day falls on 1 September.
How long does Acacia pycnantha live?
Like most fast-growing wattles it is relatively short-lived at 15 to 20 years. Plan for replacement, or use it as a nurse crop for slower long-term plantings.
Is it frost tolerant?
It handles light to moderate frost once established. Protect young plants through their first winter in colder inland districts.
How far apart should I plant it?
Plant 2 to 3 metres apart for a fast screen or shelterbelt, or 4 to 5 metres apart as individual feature trees.
