Moss phlox ‘Emerald Blue’ (Phlox subulata) is a ground cover that brightens up your flowerbeds with its starry lavender-blue flowers in spring. This variety is ideal for borders or rock gardens, creating a dense carpet of flowers and evergreen foliage. Its delicate flowers are edible, and can add a decorative and slightly sweet touch to salads or desserts. You can harvest them from spring to fall.
