Phlox subulata Emerald Cushion Blue is a low, spreading perennial that forms a dense carpet of evergreen foliage topped with masses of soft lavender blue flowers in spring. The abundant blooms create a bright, early season display that works beautifully in rockeries, on sunny banks, at the front of borders or trailing over walls. Its neat, mat forming habit helps cover soil, soften edges and add a natural, relaxed feel to planting. Emerald Cushion Blue is reliable, easy to grow and provides year round structure thanks to its evergreen leaves.

These smaller plants grow on quickly once planted and usually take around eight to twelve weeks to reach the size of a typical 9 cm growers pot. When your young plant arrives, unpack it straight away, water gently, and place it in a bright, sheltered spot for a short time while it settles. Plant out or pot on as soon as possible, keeping the soil moist while the roots establish. Once settled, it will grow into a healthy, long lasting perennial for your garden.
