Convolvulus cneorum, also known as Silverbush, is a species of bindweed, native to Europe.

Unlike many of the other species in the genus, it is a shrub rather than a vine, forming a low mound between 0.6 and 1.2 metres in height, with a similar spread. It produces 2.5 to 4 cm diameter flowers which are white with a yellow throat. These are produced at the end of stems in loose panicles and may almost completely cover the plants.The leaves are grey-green and are covered in fine hairs which give the plant a silvery appearance.[1]

Distribution

The species is found in coastal areas of Spain, Italy, Croatia and Albania[1] In Italy it is found on the coast of Tuscany and western Sicily and on the islands of Capri and Li Galli. In Croatia it is found on many of the islands off the coast. It is often found growing in cracks in rocks.[2]

Cultivation

The species prefers an alkaline soil, full sun and good drainage. It is cold hardy to -9 C.[1]
