Phlox subulata ‘Emerald Cushion Blue’ is a low-growing, evergreen groundcover with fresh green foliage and spectacular bright blue flowers in spring. This cultivar forms dense cushions that drape beautifully over rock gardens, borders, and slopes, creating a colorful carpet early in the season. Phlox subulata ‘Emerald Cushion Blue’ thrives in a sunny position with well-drained soil, is low-maintenance, fully hardy and attractive to bees and butterflies.
