Phlox subulata

Native Plants

Moss Phlox

3 Photos


Moss phlox (Phlox subulata) is an evergreen perennial phlox that is a vigorous, mat-forming groundcover, growing 3-6” tall with outstanding early spring flowers that cover the plants. Better yet, moss phlox tolerates hot and dry exposures. The fragrant, ¾” wide blooms are five-petaled with each petal notched at the tip. Moss phlox blooms from early to mid-spring in colors ranging from lavender and blue-purple to pink and white. Moss phlox performs best with full sun to filtered shade in neutral to alkaline soil. Plants are best displayed at the front of the border and rock garden with companions such as wild columbine (Aquilegia canadensis), birdfoot violet (Viola pedata), small-headed gayfeather (Liatris microcephala), fire pink (Silene virginica) and other xeric loving plants. Zones 3-9.
