Acacia
Shrubs and trees with golden or cream puffball flowers, native mostly to Australia
Acacia is a large group of shrubs and trees, mostly native to Australia, known for their small golden-yellow or creamy-white flowers clustered in spikes or heads. Many species are grown for wood, tannin, and ornamental use, and some are important in Aboriginal food traditions and as invasive species elsewhere.
- Acacia includes over 1,000 species, mostly in Australia
- Flowers are small, yellow or cream, and packed in fluffy clusters
- Seeds and gum have been used as food by Aboriginal Australians
- Bark is a major source of tannin for leather and adhesives
- Some species are invasive in South Africa and other countries
What does Acacia look like?
Acacia includes shrubs and trees with leaves that are often divided into fine leaflets or replaced by flattened leaf-like stems called phyllodes. The flowers are small and packed tightly into round or cylindrical clusters, usually golden-yellow or pale cream in colour. Each flower has many stamens, giving the clusters a fluffy look. The fruit is a pod, sometimes flat or cylindrical, containing hard seeds. Some species have a light scent, but this varies.
Where does Acacia come from?
Acacia was first named in 1754, with its name coming from Greek and Latin roots. Most species are native to Australia, where they are found in every state and habitat, from deserts to rainforests. A few species are native to Africa, the Indian Ocean, and the Pacific. Fossil evidence shows acacias have been present since at least the Eocene. The genus has been the subject of much debate among botanists, with recent changes meaning most Australian species now keep the name Acacia.
When and how Acacia blooms
Acacias flower at different times depending on the species and climate. They grow in a wide range of soils and habitats, from dry deserts to wet forests. Many are grown from seed, which often needs to be treated to break dormancy. Some species are planted for timber, tannin, or as ornamentals in gardens and parks. In plantations, especially in Vietnam and Africa, they are grown for wood and paper.
How Acacia is used
Aboriginal Australians have long used acacia seeds as food, grinding them into flour for cakes or paste. The bark of some species is rich in tannin and has been important in leather tanning and adhesives. Acacia timber is valued for tools, fuel, and musical instruments. Some species are grown as ornamentals for their flowers. In some parts of the world, acacias have become invasive, especially in South Africa.
Kinds of Acacia
There are over 1,000 species of Acacia, with most found in Australia. Notable species include Acacia baileyana, A. dealbata, and A. pravissima, which are popular in gardens. Acacia mearnsii and A. mangium are widely planted for wood and tannin. Acacia koa is native to Hawaii, and A. heterophylla to Mauritius and Réunion. Each species varies in size, leaf shape, and flower arrangement.
What Acacia means
Acacia is Australia's largest group of flowering plants and covers a large part of its forests. The name 'wattle' comes from old English for woven branches, reflecting its use in building. Some species are state or regional emblems in Australia. The bark and gum have supported industries and traditional uses. In some regions, acacias are considered invasive and are controlled by law.
