Orange wattle

Acacia saligna, commonly known as golden-wreath wattle or coojong, is a fast-growing evergreen large shrub or small tree of the family Fabaceae (subfamily Mimosoideae), endemic to south-western Western Australia and widely introduced as an ornamental, fodder and dune-stabilization plant in Mediterranean climates worldwide, where it has frequently become invasive. The plant typically reaches 3–8 m in height, with a dense, spreading, often weeping crown and smooth grey to red-brown bark. Like most adult Australian acacias, it bears no true compound leaves but instead flattened, leaf-like phyllodes; these are alternate, linear-lanceolate to sickle-shaped, 8–25 cm long and 1–4 cm wide, dark green, with a prominent midrib and one or two small basal glands. The bright golden-yellow, globose flower heads are arranged in showy axillary racemes, each head 6–10 mm across and composed of numerous tiny, fragrant flowers with conspicuous stamens. Flowering occurs in late winter and spring. The fruits are flat, linear, somewhat constricted brown pods 8–15 cm long, releasing shiny black seeds.
