A low evergreen mound turns white in early spring when Iberis sempervirens Snow Cone carries dense clusters of pure white flowers above dark green foliage. Its compact, slow-spreading growth defines sunny border edges, rock gardens, and patio containers. Bees and butterflies visit the flowers.
Grow it in full sun or light shade in well-drained clay, loam, or sandy soil. Water occasionally so summer soil stays moist but never wet. Once established, the plant tolerates dry periods; light trimming after flowering helps keep the cushion dense.
