Sydney golden wattle
Acacia longifolia, family Fabaceae
A fast-growing Australian shrub or tree with golden flower spikes and bead-like seed pods
Sydney golden wattle is a shrub or small tree native to coastal southeastern Australia. It bears bright golden-yellow flower spikes from winter to spring, narrow leaf-like phyllodes, and twisted leathery pods that resemble strings of beads.
- Flowers from June to October in Australia
- Pods often twisted like a string of beads
- Produces yellow dye from flowers, green from pods
- Roasted seeds were eaten in Tasmania
- Banned in Portugal for being highly invasive
What does Sydney golden wattle look like?
Sydney golden wattle grows as a shrub or upright spreading tree up to 10 metres tall. It has smooth grey bark and narrow, straight or slightly curved phyllodes, modified leaf stalks that function like leaves. Its flowers form dense cylindrical spikes of golden yellow, usually 2 to 5 centimetres long. The seed pods are thin, leathery, and often tightly coiled or twisted, giving them the look of a string of beads.
Where does Sydney golden wattle come from?
This species is native only to the coastal regions of southeastern Australia, from southern Queensland through New South Wales, Victoria, and into South Australia and Tasmania. It was first described in 1802 as Mimosa longifolia and moved to the genus Acacia in 1806. Two subspecies are recognised: one with mostly straight pods and another, A. longifolia subsp. sophorae, with coiled pods and thicker phyllodes, found on Tasmanian dunes.
When and how Sydney golden wattle blooms
It flowers between June and October in its native range. The plant thrives in sandy soils, especially on coastal dunes, heathlands, and woodlands. It grows quickly, tolerates drought and light frost, and can be propagated from seed after scarification or hot water treatment. It is widely planted for hedges, screening, and stabilising slopes or road embankments.
How Sydney golden wattle is used
In Australia, it is grown in gardens and used for soil binding on banks and dunes. Its flowers yield a yellow dye and its pods a green one. Aboriginal people in Tasmania roasted the ripe seeds for food. The bark has limited use in tanning sheepskins. Outside Australia, it is cultivated in places like California but banned in Portugal due to invasiveness.
Kinds of Sydney golden wattle
Two subspecies are accepted. Subsp. longifolia has longer, flexible phyllodes and mostly straight pods. Subsp. sophorae features shorter, sometimes fleshy phyllodes and pods that are typically coiled or twisted. The latter grows mainly on coastal sand dunes in Tasmania.
What Sydney golden wattle means
While not an official national emblem, it belongs to the wattle group that symbolises Australia. Elsewhere, it is problematic: classified as invasive in Portugal, South Africa, and New Zealand because it spreads rapidly, alters soil chemistry through nitrogen fixation, and displaces native plants. In South Africa, a biological control wasp reduces its seed production by over 90%.
