(='Ice Blue') Short spikes of starry pale-blue flowers completely smother the mounding grey-green foliage of this low creeper in late spring. A beautiful edging plant, great when massed or grown in the rock garden. Tolerates heat and drought once established. Clip or mow after flowering to maintain an especially dense and compact habit. Clumps are easily increased by digging and ripping apart into smaller pieces in spring or early fall.
