Notes

Often confused with Calystegia hederacea.

The type of this species is a double flowered plant, cultivated in Britain and now naturalized in Europe and North America. It was originally collected near Shanghai.

Plants intermediate between C. pubescens and C. hederacea, from Japan, where they probably are sympatric, have been named as Convolvulus japonicus Thunb. ( = Calystegia sepium var. japonica (Thunb.) Makino, non Calystegia japonica Choisy). Their status are unknown.
