How to grow moss phlox

When to plant moss phlox

Moss phlox is a dense, mat-forming native groundcover that blankets itself in pink, lavender, or white flowers in spring (NC State: late April to early May). Plant or divide in spring or fall in moist, well-drained, humus-rich soil in full sun; cut stems back by half after flowering to keep the mat dense.

Moss 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.
