Native to southern Europe.
Naturalised in many parts of south-eastern Australia (i.e. in central and southern New South Wales, southern Victoria, Tasmania and south-eastern South Australia). Also widely naturalised in New Zealand.
Greater bindweed (Calystegia silvatica) is often a weed of hedgerows, gardens, pastures, disturbed sites and waste places in temperate regions. However, it also invades forest margins and riparian areas. For example, in the Tamar Valley region in Tasmania, it is invading bushland along walking trails and infests the margins of the River Tamar. It is also regarded as an environmental weed in Victoria, where it is thought to pose a serious threat to one or more vegetation formations.
