Field Bindweed

It's a shame bindweeds are such a nuisance in the garden because they're actually rather pretty. This is the baby one which actually carries the name Convolvulus by which the family is known. The rest are in the genus Calystegia. 
Convolvulus arvensis, Field bindweed, is the often found crawling around on the ground rather than desperately scrambling up the nearest vertical surface like the others. The flowers close at the end of the day, revealing their candy-like insides only to the sun itself on the morrow.
