Gibraltar Candytuft

Gibraltar candytuft is an evergreen, half-woody Iberis with narrow leaves and a low, flat-topped outline. Dense, flat flower clusters range from white to reddish lilac; mature plants can reach about 12 inches tall and spread farther in favorable sites.

The common name can be applied to other candytufts, so check the botanical name when species identity matters.

The species grows in cliff crevices and suits sunny rock gardens or a protected stone wall. It flowers from May through July. Older species accounts report a spread of 2–3 feet in favorable sites, so allow room beyond a small nursery clump.

In colder parts of its garden range, the species survives only mild or moderately severe winters; choose a sheltered sunny site where winter cold is a concern.
