Green Wattle

Botanical Overview

Green Wattle (Acacia decurrens) is a species in the Fabaceae family. The legume family (Fabaceae) includes trees, shrubs, and herbs that produce pods (legumes) and form nitrogen-fixing root nodules through symbiosis with bacteria. The flowers are typically pea-shaped with five petals. This large family provides food staples, timber, and numerous medicinal species. Although comprehensive ethnobotanical records are limited, phytochemical studies have identified 30 compounds in this species, suggesting potential medicinal value.

General Description

It is a tall shrub to tree with bipinnate, dark green leaves, spherical heads of golden yellow flowers and thinly leathery pods. Cultivated throughout Australia, Acacia decurrens has naturalised in other Australian states and introduced to many other countries.
