Candytuft 'Apple Blossom'-Iberis Umbelleta (annual)-low growing often seen in rock gardens. Can also be grown in borders or containers. Drought tolerant works wonderfully in stone wall crevices, as an edging or a ground cover. Full sun, though it will adapt to partial shade. An average soil is fine, as long as it's well drained. Wet feet will rot the plants or cause disease.
