Beautiful plant my friend and Silverbush is a fast growing evergreen shrub native to coastal areas of Spain, Italy, Croatia and Albania. It is a member of the morning glory/bindweed family, Convolvulaceae, that includes many weeds as well fine garden plants. Plants form dense rounded mounds of one to two inch long, lance-shaped leaves covered with fine silky silver-grey hairs. Panicles of funnel shaped white flowers white yellow centers, l.5 to 2 inches wide, open from pink buds from early spring to late fall. Although not hardy in zones colder than 8, silverbush makes a good container plant that can be wintered indoors. The genus name, Convolvulus, comes from the Latin verb, convolvere, meaning to roll together referring to the twining nature of most of the plants in the genus.

Convolvulus sabatius is a deciduous herbaceous perennial with a trailing habit. Its mid green leaves are ovate with entire margins, up to 30mm long and 25mm broad. Its stems are herbaceous, are able to twine and climb and die back to ground level each year. Its blue/ purple flowers are funnel shaped and up to 25mm across.

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.
