General Description
Tree & Wood Descriptions for: Acacia mollissima syn. A. mearnsii

Product Sources

Some material from this species is reported to be available from sustainably managed or other environmentally responsible sources.

Black wattle is also reported to be cultivated principally for its bark which yields tannin.

Tree Data

The tree is described as rather small in size, and attains a height of only about 20 to 50 feet (6 to 15 m) at maturity.

Sapwood Color

The sapwood is very pale brown in color and is usually not distinct from the heartwood.

Heartwood Color

The heartwood is light brown with reddish markings, or pale brown with a pinkish tinge, and is not too distinct from the sapwood.


The grain is commonly interlocked or crossed.


The wood has a moderately fine and uniform texture.


The wood has a medium luster.


There is no characteristic odor or taste.

Movement in Service

The material is reported to have rather poor dimensional stability, and tends to move significantly after manufacture.

Natural Durability

Natural resistance to decay is reported to be very low, and the wood is readily attacked by powder-post beetles (Bostrichydae and Lyctidae) and termites.

Resistance to Impregnation

The heartwood has been described as fairly or moderately resistant to impregnation. The sapwood absorbs preservatives readily.
