Convolvulus sabatius, commonly known as Blue Rock Bindweed, Mauritian bindweed or Ground Morning Glory, is native to parts of Spain and Italy and parts of North Africa. Convolvulus sabatius is synonymous with Convolvulus mauritanicus.

The etymological root of the binomial name Convolvulus is derived from the Latin convolvere meaning ‘ to coil or twist’, in reference to twining climbing habit of a umber of this genus. Sabatius is named after the region Vada Sabatia in Italy where this species was first described.
