Convolvulus cneorum, also known as silverbush, is a species of flowering plant in the family Convolvulaceae, which contains many plants described as "bindweed". However, unlike other species in the genus, it is an evergreen shrub rather than a vine, forming a low mound 0.6–1.2 m (2 ft 0 in–3 ft 11 in) in height, with a similar spread. It produces 2.5–4 cm (1–2 in) 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.
