Creeping Phlox: Spring Carpet of Color
Phlox subulata
Creeping phlox transforms slopes and rock gardens into waterfalls of pink, purple, or white in early spring. Evergreen needle-like foliage covers bare soil the rest of the year. Drought-tolerant once established.

Care & growing tips
Plant in well-drained, even sandy soil in full sun. Shear lightly after flowering to encourage dense growth. Divide every 3–4 years if center thins. Spreads slowly — plant on 12-inch centers for faster coverage.

Frequently Asked Questions
01 When should I shear creeping phlox?
Right after the spring flower show fades — shear back by 1/3 to encourage dense new growth. This keeps the mat tight and prevents woody centers. Some varieties will produce a small second flush of blooms in late spring after shearing.
02 Can creeping phlox grow in shade?
Not reliably. It needs at least 4–6 hours of direct sun to bloom. In shade, foliage looks thin and flowers are sparse. For shade slopes, try creeping sedum, vinca, or native pachysandra — each handles less sun than creeping phlox.
03 Does creeping phlox spread aggressively?
Slowly and well-behaved — it expands about 6 inches per year from the original plant. Not invasive. For full coverage of a slope in 2–3 years, plant on 12-inch centers. For fastest coverage, work in compost before planting and water regularly the first season.
