Emerald Cushion Blue Creeping Phlox

Emerald Cushion Blue Creeping Phlox (Phlox subulata 'Emerald Cushion Blue') is a beloved, low-growing perennial groundcover that transforms the spring garden with a breathtaking carpet of pale lavender-blue flowers smothering a dense, cushion-like mound of fine, evergreen needle-like foliage. One of the most reliable and spectacular early-season bloomers available, Emerald Cushion Blue puts on a flower show of such intensity in spring that the foliage beneath is almost completely hidden by a solid mass of soft blue-violet blooms.

Grown from professional-grade nursery stock, Emerald Cushion Blue Creeping Phlox arrives with a strong, well-established root system ready to establish quickly and spread into a lush, weed-suppressing mat of evergreen foliage. Its compact, cushion-forming habit makes it an outstanding choice for rock gardens, stone walls, sunny slopes, border edges, and cascading over retaining walls, where its spring bloom display and year-round evergreen texture provide enduring ornamental value.

• Breathtaking Spring Carpet of Pale Blue Blooms: A spectacular mass of pale lavender-blue flowers smothers the plant each spring in such abundance that the foliage is almost entirely hidden — creating one of the most impressive early-season floral carpet displays available for the sunny rock garden, border edge, or sloping landscape.
• Dense Evergreen Cushion-Forming Habit: Fine, needle-like evergreen foliage forms a tight, dense, cushion-like mat that provides attractive year-round ground-level texture and structure long after the spring blooms have faded — making Emerald Cushion Blue a four-season ornamental asset in the landscape.
• Excellent Rock Garden & Slope Plant: Thrives in the fast-draining, lean conditions of rock gardens, dry stone walls, sunny slopes, and retaining wall edges where many other groundcovers struggle — making it a premier choice for challenging, well-drained garden situations.
• Drought Tolerant Once Established: After its first season in the ground, Emerald Cushion Blue develops deep roots and demonstrates excellent tolerance for dry conditions, making it a reliable, low-maintenance groundcover for water-wise garden designs in sunny exposures.
• Professional Grade Root System: This plant arrives with a healthy, well-developed root system that establishes readily and spreads steadily to form a beautiful, weed-suppressing groundcover mat of evergreen foliage and spectacular spring blooms.

This 4" healthy live plant thrives in full sun with low to moderate water and excellent drainage — Emerald Cushion Blue Creeping Phlox does not tolerate poorly drained or consistently wet soils and will decline in heavily shaded locations. A cold-hardy, long-lived perennial groundcover suited to USDA Hardiness Zones 3–9. Mature height reaches 4–6 inches with a spread of 18–24 inches. Primary bloom time is early to mid spring (March–May). Trim lightly after blooming to maintain a compact, tidy cushion habit and encourage dense regrowth through summer and fall.
