Acacia saligna
Synonyms: Acacia cyanophylla, Acacia bracteata, Acacia lindleyi, Mimosa saligna, Racosperma salignum
Common names: Orange wattle
Acacia saligna (golden wreath wattle, orange wattle) is a shrubby tree in the pea family (Fabaceae) that is native to Australia. It is grown as an ornamental and has become naturalized in coastal and southern California as well as in other Mediterranean climates in South Africa, parts of southern Europe, and where it is not native in southeastern Australia. Orange wattle has long (7-21 cm), thin leaves (each with a prominant midvein) that differentiate it from other Acacia species. Flowers are arranged in racemes consisting of 2-8 heads each. Seed pods are narrow, straight, and not hairy. Plants can reproduce vegetatively and produce copious amounts of seed. Its dense canopy can shade out other plants. Wildfire favors its spread by promoting regrowth and germination.
