Convolvulus cneorum - Silverbush or shrubby bindweed - is a species of flowering plant in the family Convolvulaceae, which contains many plants described as "bindweed". However, unlike other species in the genus, this one 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. The leaves are grey-green and are covered in fine hairs which give the plant its silvery appearance.

Plant this shrub in the sun, typically in a mineral garden, or in a tray. The ground must be well drained, and keep in mind that if it is less than 10-12 ° C in your area in winter, you will have to shelter it. In this case, prefer growing it in a big pot. Plant in a hole at least twice as big as the root ball. Soak the roots before planting, this will greatly improve the chances of recovery, regardless of the conditioning. You can form a bowl around the foot, which will be used for watering during the first months. Tamp the soil well around the roots (do not hesitate to use all the weight of your body). Water copiously until filling the planting bowl. After planting, add some compost to the top of the soil - and mulch! In pots, choose a big container.
