The Phlox is native to the eastern and central part of North America and the Phlox subulata is commonly named moss phlox or creeping phlox. The Phlox is a genus from the Polemoniaceae family. In Greek the word phlox means flame in reference to the intense flower colors of some varieties. Subulata is Latin and means awl-shaped and refers to the awl or needle shaped leaves.

Despite the name I would call the color of the flowers of the Phlox subulata ‘Emerald Cushion Blue’ lilac and not blue. They are beautiful anyway.

The moss phlox is a beautiful mat-forming evergreen perennial. In spring the Phlox subulata ‘Emerald Cushion Blue’ forms a cushion of lilac fragrant flowers. The moss phlox gradually spreads but is easy to restrain. You can cut or pull away the parts where you do not want them. The Phlox subulata ‘Emerald Cushion Blue’ is salt and drought tolerant and very suitable for rock gardens and as groundcover.
