[Cal-IPC] Australia native, Invasive: Acacia longifolia (Sydney golden wattle) is a summer-blooming shrub or tree in the pea family (Fabaceae) that is native to Australia. It is variable in size and has been cultivated as an ornamental. Its leaves are leathery and strap-like, finger-wide and long, with parallel veins and have a conspicuous basal gland with no resinous margins. Flowers are yellow and arranged in short spikes in leaf axils. This Acacia is a prolific seeder that can form large seed banks; long-term control is difficult if populations are left to spread. As of this posting, it has been reported in California's coastal counties from Sonoma County south to San Diego. Outside of California, Sydney golden wattle has become invasive in other parts of Australia (Victoria, New South Wales), New Zealand, South Africa, Spain, Portugal and Brazil.
