Hedge bindweed, Calystegia sepium
, is able to spread rapidly to creep between cultivated plants, making it difficult to eradicate. It's able to re-grow from small pieces of cream-white root, so cultivating a border often aids its spread. It can make large clumps of foliage, obscuring and smothering small plants. Seed is produced following the cream-white trumpet flowers, which also allows this weed to spread.
This climbing, twining perennial dies down in winter but grows rapidly in spring and summer to smother other plants.
