Acacia decurrens mollis (Black Wattle)

Acacia decurrens mollis (Black Wattle) is a subspecies of Acacia decurrens, a species of evergreen tree native to southeastern Australia. The Black Wattle is valued for its fast growth, adaptability, and its use in various applications. It is a medium-sized evergreen tree with feathery, dark green foliage, clusters of yellow flowers, and dark brown to black bark.

The Black Wattle is a medium-sized tree that can reach heights of up to 10 to 20 meters (33 to 66 feet) at maturity. It has a spreading growth habit with a rounded or dome-shaped canopy. The bark of the Black Wattle is dark brown to black in color, hence its common name.

The foliage of the Black Wattle consists of bipinnate leaves, meaning the leaves are divided into multiple pairs of leaflets. The leaflets are dark green and have a lanceolate or elongated shape. They give the tree a feathery and fern-like appearance. 

In late winter or early spring, the Black Wattle produces clusters of small, globular yellow flowers. The flowers are densely packed and create a vibrant display. They are rich in nectar, attracting bees, butterflies, and other pollinators. The flowers are followed by elongated seed pods that contain small seeds.

The Black Wattle is highly adaptable to various soil types and climates. It can tolerate both sandy and clay soils and is relatively drought-tolerant once established. It prefers full sun to partial shade for optimal growth.

The Black Wattle has both ornamental and practical uses. In landscaping, it is often planted for its attractive foliage and bright yellow flowers, which add color and texture to gardens. It can also be used for erosion control, windbreaks, and as a nitrogen-fixing species in agroforestry systems. Additionally, the wood of the Black Wattle is used for fuel, construction, and various woodworking projects.
