Acacia mearnsii

 

Black Wattle

Acacias, or wattles, are shrubs and trees that belong to the pea family. They are evergreen plants grown for their attractive foliage and bright yellow scented blooms. The genus varies in size from small shrubs, ideal for containers, to large trees of 10m or more in height. Acacia mearnsii is fast-growing and extremely invasive. It is a leguminous tree, native to Australia, where it used for preventing soil erosion, as green manure (for its nitrogen-fixing qualities), the wood is useful for construction, and for burning, and the bark is useful as a source of tannins. It bears dark green feathery leaves, and globular heads of pale yellow, fragrant flowers from early Spring to late Summer, followed by finely hairy dark brown pods
