Phlox subulata 'Emerald Cushion Blue' (Creeping Phlox)

Phlox subulata 'Emerald Cushion Blue' is a cultivar of creeping phlox, a low growing, mat-forming, native evergreen perennial known for its flowers. The 'emerald' and 'blue' parts of the cultivar are named for the contrasting colors of the plant's lush green foliage and the delicate flowers produced in the mid to late spring which are lavender-blue in appearance, slightly darker than other blue-flowering phloxes like 'Oakington Blue Eyes'. In addition, the 'cushion' part of the name is drawn from this cultivar's tendency to form thick, consistent carpets of foliage after it gets established.

Also commonly referred to as moss phlox, Phlox subulata 'Emerald Cushion Blue' is an excellent ground-cover plant, only growing to 4-6" tall but spreading easily to occasionally 2' wide or more. 'Emerald Cushion Blue' moss phlox also grows well in a wide-variety of soils, provided that it's in a well-draining site, meaning that it works for edgings and borders as well as container growing, and these plants are even hardy enough to put on full blooms in the middle of scorching hot rock gardens.
