Greater bindweed (Calystegia silvatica), also known as convolvulus
Greater bindweed
A robust, sprawling, climbing, hairless perennial, growing to four metres and producing very large, white, trumpet-shaped flowers. It has large triangular or arrow-shaped leaves. The aerial parts usually die down in winter, while an extensive underground rhizome system makes the plant difficult to control.
