Summary

Acacia longifolia, commonly known as Sydney Golden Wattle, is a fast-growing evergreen tree or shrub native to coastal areas and stabilized sand dunes in southeastern Australia, including the extreme southeast of Queensland, eastern New South Wales, eastern and southern Victoria, and southeastern South Australia. It typically reaches a height of 7–10 meters (23–33 feet) within five to six years and can grow up to 8 meters (26 feet) tall. The species exhibits smooth to finely fissured greyish bark and produces showy, bright yellow flowers during the spring and winter months, which are highly attractive to pollinators.

Sydney Golden Wattle is valued for its rapid growth, ornamental flowers, and ability to stabilize soil, making it suitable for use in hydroseeding on banks and low maintenance areas like road batters. It is also used as a hedge plant or for screening purposes. In Southern California, it is popular as a street canopy tree due to its quick growth, drought tolerance, and resilience to harsh pruning. Acacia longifolia thrives in full sun and can adapt to a range of soil types, preferring those with medium to fast drainage. However, it is potentially invasive outside its native range, particularly in Portugal and South Africa, where it out-competes local species. Gardeners should be cautious and check local regulations before planting to avoid contributing to its spread as an invasive species. It is invasive in Portugal, South Africa, and New Zealand, forming dense stands in sand dunes and coastal areas.CC BY-SA 4.0
