Reviewed by Debra LaGattuta Creeping phlox is a low-growing, mat-forming flowering plant that is often seen spreading as a thick ground cover, in rock gardens, and even in crevices of stone walls.

Creeping phlox can survive the winter without any special care in growing zones 4 to 9. If you live in zone 4 or lower, protect your plants’ roots by spreading a layer of mulch over the plants.
