How to grow creeping phlox

When to plant creeping phlox

Creeping phlox is a low native groundcover that blooms in spring (NC State: spring into early summer) with blue-violet to white flowers, spreading by above-ground runners to form a mat. Plant or divide in spring or fall in moist, well-drained, slightly acidic soil; keep it moist the first year, and deadhead and allow air circulation to prevent powdery mildew.

Creeping Phlox is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
