Silver Wattle (Acacia dealbata) is a distinctive tree widely distributed throughout eucalypt forests and woodlands in eastern Australia. It's easily identified by its silvery blue-green feathery foliage and yellow flowers during spring. In the past it has been more valued for horticultural uses than for its timber.
The tree grows to 30m or more in height with a diameter of up to 75cm when mature. When grown in the open it develops a spreading habit and may form a crown 15m across.
Silver Wattle varies in colour from light brown to subtle pink. These lighter tones mean it is increasingly in demand for furniture. Its very distinct rings can create a striped pattern when backsawn that make it an appealing timber for furniture designers and manufacturers.
It is a lighter, less dense timber than eucalypt or the related blackwood and its figure provides a counter point to this closely related but darker species.
The wood is easily split and fairly tough. When planed and dressed it produces a very smooth surface for furniture and it polishes well.
In Tasmania, Silver Wattle occurs as the dominant shrub in dry eucalypt forests and woodlands. It can also be found as a tall understory species in wet eucalypt forests.
The tree grows very quickly. It generates readily after fire from soil-stored seed or root suckers. This means the species is well-suited to the Australian bushfire environment.
Silver Wattle is not very long lived and dies out as the eucalypt overstory matures. Future supplies will be readily available from stands of regrowth which will be harvested on rotation between 70 and 90 years.
