The Q&A Archives: Silver Wattle

Question: Do you sell the Acacia Dealbata (silver wattle)? I need a shade tree for some of my delicate plants that burn up in the hot Rocklin sun. I have read about this tree from Australia that looks beautiful and can grow in about any hot climate with lousy soil rapidly. Do you have any information on it? It looks like more fun than a Rayburn Ash.

Answer: Silver Wattle (Acacia dealbata) is also sold as Acacia decurrens var. dealbata. It's a member of the Fabaceae family and the recommended Temperature Zones for this tree are:
sunset: 8-9,14-24
USDA: 9-11

Young trees are very sensitive to frost, but mature trees aren't bothered by it. Silver Watter originated in Australia (New South Wales, Victoria and Tasmania).

It is an evergreen tree, fast growing to 30 to 50 feet tall and wide with a rounded shape; smooth, gray bark; gray green to bluish green, fern like leaves. It grows best in full sunshine, needs good drainage, and is drought tolerant once established.

The Acacia dealbata blooms in late winter to early spring, producing large clusters of very fragrant, small golden yellow flower balls, 0.25 inch in diameter, each with 20 to 25 actual flowers.

Because they are fast-growing, they are relatively short-lived for a tree.

Monrovia does not grow this plant, and I can find only one source in California where you might be able to find one. Contact Australian Native Plants Nursery in Ventura, 805-649-3362.
