Estimated Native Range
Summary
Acacia dealbata, commonly known as Silver Wattle, is a fast-growing evergreen tree native to southeastern Australia, including Tasmania. It thrives in various habitats such as eucalyptus forests, woodlands, and coastal areas. This species can reach up to 98 feet in height and is characterized by its bipinnate, silvery-gray leaves that give it a distinctive shimmering appearance. The bright yellow, fragrant flowerheads bloom in late winter to early spring, providing a striking contrast against the foliage and making it a highly ornamental plant.
Silver Wattle is valued for its rapid growth and attractive foliage, as well as its ability to fix nitrogen in the soil, which can improve soil fertility. It is commonly used in cultivation for ornamental purposes, as a windbreak, and for erosion control. In terms of care, Acacia dealbata prefers full sun to light shade, well-drained soils, and can tolerate drought once established. It is relatively low-maintenance but can be susceptible to root rot in poorly drained soils. While it has no major disease issues, it can become invasive outside its native range due to its prolific seed production and should be planted with caution.CC BY-SA 4.0
