Perennial of the Convolvulaceae family, native to the Near East, mainly from Turkey, Lebanon, and Syria, where it grows on calcareous rocks, scree, and arid stony slopes, in full light.
It forms a low and spreading tuft, 10 to 20 cm in height, with branched stems. The foliage is medium green, with a characteristic white margin that outlines each leaf. The stems, petioles, and flower buds are covered with long silky white hairs, very visible, giving the plant a hairy and luminous appearance, particularly striking in grazing light.
The large funnel-shaped flowers are pure white, with a pale yellow center, borne on hairy peduncles. In its natural habitat, flowering extends from May to July.
In cultivation, it requires impeccable drainage, very poor and stony soil, in full south exposure. It does not tolerate prolonged winter humidity. Its exact hardiness remains to be confirmed depending on the provenance, but it seems to withstand moderate frosts under conditions of strict winter drought.
