Plant Common Name

Ever-blooming Wattle, Silver Wattle, Water Wattle

General Description

Bearing its sunny fragrant flowers nearly year-round, this fast growing evergreen shrub or small tree is also noteworthy for its attractive foliage and its adaptability.

In spring large sprays of small golden pompon-like flower heads bow the spreading branches of this acacia, attracting numerous bees. The flowers are nicely complemented by the narrow, willowy, gray-green "leaves", which are actually expanded leaf stems known as "phyllodes." Sporadic rebloom occurs throughout the year if temperatures remain mild. In cooler areas such as Great Britain and the Northwest United States peak bloom is typically in summer or early fall. Small pea-like seed pods follow the flowers, aging to brown. Plants sometimes self-sow.

This sun-loving acacia likes good drainage and tolerates saline, alkaline, and seasonally damp soil. It grows rapidly from seed, making it useful for large roadside or erosion-control plantings. It also makes a good garden specimen, especially where its fragrant flowers can be appreciated at close hand.

This potentially invasive plant has escaped gardens in California, Florida, and other areas through self-sowing.
