Iberis is so named because many members of the genus come from the Iberian Peninsula in south west Europe.

The glossy, evergreen foliage forms a billowing mound, with many fragrant, pure white flowers in tight clusters [5] for several weeks during spring and early summer.

[6] When grown in a garden it may require light pruning right after blooming, but otherwise plants can be left alone in fall and early spring.

It prefers a well-drained site, so heavy clay soils that stay wet in winter should be avoided.

[7] Iberis sempervirens survives in USDA hardiness zones 3–9 with mean annual minimum temperatures of −23 to −21 °C (−10 to −5 °F).
