Phlox subulata 'Emerald Blue' has clear lavender-blue, star-shaped flowers over low, rapidly spreading, needle-like evergreen foliage. Flowering in early spring, 'Emerald Blue' is lovely with spring bulbs, edging the walk or border, or used as a ground cover on a sunny bank. It is one of the best early blooming varieties available.
A perennial, also known as Creeping Phlox or Moss Pinks, Phlox subulata is native to the eastern half of North America, where it is typically found on sandy or rocky places, savannas, rocky ledges or slopes, and clearings.
Phlox subulata 'Emerald Blue' prefers full sun and average to dry, well-drained soil. It is excellent for sandy or gravelly soils and tolerates hot dry conditions better than other types of Phlox. It is also suitable for coastal conditions. Plants may be sheared back after blooming to encourage fresh foliage.
