Hedge bindweed or bellbind (Calystegia sepium) with its pure white trumpet flowers is a familiar sight, choking plants in borders and twining around any plant shoot or cane. The smaller field bindweed (Convolvulus arvensis) with white or pink flowers is problematic in long grass and bare soil.
Bindweed refers to two similar trumpet-flowered weeds, both of which twine around other plant stems, smothering them in the process.
They are not easy to remove as they persist from a perennial root system. The roots are usually white and brittle and, if broken, are able to regenerate from the smallest sections.
Calystegia sepium (bellbind or hedge bindweed) climbs with strong twining stems, has large heart-shaped leaves and large white trumpet flowers. It is most often seen as a hedgerow plant or weed, scrambling over and often smothering hedges and shrubs of all sizes and even smaller ornamental trees.
Convolvulus arvensis (field bindweed) is a weaker-stemmed plant, with smaller white or pink trumpet-shaped flowers, but otherwise similar in appearance to bellbind.
