Calystegia sepium, the Hedge Bindweed, is a member of the Convolvulaceae family and is not usually a valued garden plant, but rather a vigorous weed that you can see in flower now. Weeds are simply plants in the wrong place, and although this is not usually a desirable plant it does have a certain beauty. The climbing stems die back during the winter only to re-emerge in the spring; they will twist themselves up and over pretty much everything.
The heart-shaped leaves are a mid-green colour and the plant’s white trumpet-shaped flowers are short-lived and can be 7cm across. Hedge Bindweed can climb to around four metres, and is not fussy about the conditions it grows in. It can grow back from even a small piece of underground rhizome, which look like spaghetti and can go down 15 feet. The best way to control this weed is by digging and removing its roots. If the stem has twined around an ornamental plant, unwrap it carefully. Be sure not to put any rhizomes or stems in the compost or they will infest it. For more information, see the RHS website.
