{{Argicultural pest | common_name = Bindweed, Morning Glory | latin_name =Calystegia | image =Calystegia sepium ssp sepium bluete.jpeg | caption = | range = The genus has a cosmopolitan distribution in temperate and subtropical regions, but with half of the species endemic to California | description = Bindweed are annual or herbaceous perennial twining vines growing to 1-5 m tall, with spirally arranged leaves. The flowers are trumpet shaped, 3-10 cm diameter, white or pink, with a sometimes inflated basal calyx. Some of the species, notably C. silvatica, are problematic weeds, which can swamp other more valuable plants by climbing over them, but some are also deliberately grown for their attractive flowers. | control = Bindweed is difficult to control once it becomes established. It is a very persistent weed, so control methods must necessarily be more persistent.
