#ProPlantTips for Care:

Emerald Blue Creeping Phlox needs to be planted in a full sun area in well-drained soil for the best growth possible. Provide moderate yet consistent moisture for new plants their first year, but after, these plants are very self-sufficient. Provide moisture during times of drought and extreme heat, and to further help with moisture retention, add a 3-4 inch thick layer of mulch over the soil surface. Prune/shear mounds immediately after flowering and remove up to a third of the top growth for a clean start.

  • Full Sun
  • Well-Drained Enriched Soil
  • Moderate Moisture
  • Prune After Flowering
  • Very Easy Care

This flowering perennial is positively striking in the spring and will effortlessly make a difference in your landscaping. Order your very own striking Emerald Blue Creeping Phlox today! This is a fan favorite and won't last long!
