Care of the plant Convolvulus sabatius or Blue rock bindweed |
The genus Convolvulus, family Convolvulaceae, includes 600 species of herbaceous climbing plants and shrubs with a cosmopolitan distribution. Some species are: Convolvulus sabatius, Convolvulus cneorum, Convolvulus tricolor, Convolvulus sepium, Convolvulus althaeoides, Convolvulus floridus, Convolvulus canariensis. Common names: Blue rock bindweed, Ground Morning Glory, Ground blue-convolvulus. This species is native to North Africa. They are herbaceous plants with a creeping or covering habit that reach 20 cm (7.87") in height. They have small, oval, gray-green leaves. Most interesting are the abundant trumpet-shaped blue or lilac flowers; they bloom in summer and early fall. Blue rock bindweed is used in rockeries, on edges and to cover slopes. It's appropriate for pots especially in places with cold winters as it allow us to put them in shelter. Convolvulus sabatius needs full sun exposure to flower properly. On cloudy days the flowers do not open. It does not resist frost. The soil must be very well drained: it prefers sandy soils that contain organic matter. Water moderately, waiting for the soil to be completely dry. Fertilize with compost in early spring. Prune in late winter to make them sprout more vigorously. Ground Morning Glory is a quite resistant plant to pests and diseases but sensitive to excess humidity. Ground blue-convolvulus propagates by seeds sown in spring in their final location or by division. |
