[Cal-IPC] Australia native, invasiveness: Atriplex semibaccata (Australian saltbush) is a low-statured, spreading, shrubby perennial (family Chenopodiaceae) that is native to Australia. It is distinguished by its small, grey-green leaves that are white on the underside and red, diamond-shaped fleshy fruits. Australian saltbush was introduced as a forage plant in the 1920s. Since then, it has escaped cultivation and is now invasive in coastal grasslands, scrub habitat, and the higher ground of salt marshes, where it can form dense stands and displace native plants. Australian saltbush has become an alternate host plant for the pygmy blue butterfly since its introduction into North America. (link added by Mary Ann Machi)
