No species reported


Classified as an aggressive colonizer plant, the sweet acacia is invasive in Australia, islands in the Pacific and the Caribbean, and in the United States. This plant creates thick, thorny hedges which make shade that can kill native species beneath and block out or cause injury to livestock trying to graze. Native to North America, it was widely introduced as an ornamental plant and was cultivated to create an addition to perfumes. Its growth shape causes further issues, as it grows in a vase shape that creates growing difficulties for local plants and takes over driveways and roads.


Uses


Garden Use

While sweet acacia is used as a specimen shrub in landscaping and some southern flower gardens, it is primarily found growing as a natural fence or wildlife barrier. The sharp thorned bush is also useful in bee and butterfly gardens; it produces fragrant flowers in the spring and summer that attract pollinators to the area.
