The illustrated growing guide
Creeping Phlox (Moss Phlox)
Phlox subulata
Family Polemoniaceae
Est. zones 3-9

The carpet of color that flows over spring retaining walls and slopes in a solid sheet of pink, blue, or white — a native, drought-proof, semi-evergreen mat that needs only sun and sharp drainage. Shear it lightly after bloom to keep it dense. Not to be confused with tall summer garden phlox; this one hugs the ground in early spring.
