Calystegia sepium (larger bindweed, hedge bindweed, Rutland beauty, bugle vine, heavenly trumpets, bellbind, granny-pop-out-of-bed) (formerly Convolvulus sepium) is a species of bindweed, with a subcosmopolitan distribution throughout the temperate Northern and Southern hemispheres. It is an herbaceous perennial that twines around other plants, in a counter-clockwise direction, to a height of up to 2-4 m, rarely 5 m. The pale matte green leaves are arranged spirally, simple, pointed at the tip and arrowhead shaped, 5-10 cm long and 3-7 cm broad.
