large bindweed (Calystegia sepium), on the left, has smaller pointed bracts while greater bindweed (Calystegia silvatica), on the right, has larger bracts with rounded tips (Photo: Sheldon Navie)
field bindweed (Convolvulus arvensis) is also similar, but does not have any bracts at the base of its flowers (Photo: Trevor James)

Notes
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.
