The climber with large white trumpet flowers covering hedges and riverside reedbeds in summer. It always twines the same way, anticlockwise.

Where it grows

Streams and ditches · Roadsides and waste ground · Fields and pasture · Town and roadside

Also known as

bellbind, larger bindweed

In flower

How to tell it

A twining smooth stem to three metres. Arrowhead leaves with two well-marked square lobes at the base. Pure white funnel flowers five to seven centimetres, with no coloured veining. Behind the flower two large bracts completely hide the calyx, which separates it from the bindweeds.

What it is confused with

Field bindweed

Convolvulus arvensis

Harmless confusion

Size decides: two centimetres on field bindweed, six on hedge bindweed. And field bindweed often has pink stripes on the funnel, this is pure white. Both are purgative.

Open sheet

What it is for

None. Like the others in the family it contains strongly purgative resin glycosides, and the root was used as a violent laxative. It is neither eaten nor tasted.
