Moss Phlox | Plant Profile

Moss Phlox (Phlox subulata) are mat forming groundcovers with an abundance of small flowers in spring. The fragrant flowers can be a variety of colors. The flowers cover the entire plant when in full bloom, creating a carpet of pink or white. The dark green leaves can remain partially evergreen throughout winter.

Moss Phlox prefers medium moisture, well drained soils in full sun.

Moss Phlox are beautiful groundcover additions to rock gardens, slopes, and spilling over rock walls. They bring bright color to low borders. If let to naturalize, Moss Phlox can make for extremely ornamental hillside meadows.


Moss Phlox Characteristics

Moss Phlox are highly ornamental groundcover perennials with a profuse spring bloom. The best flowering occurs in full sun, but sun-dappled shade can be appreciated in hot climates. Moss Phlox can be tolerant of rocky and thin soils, which makes them an ideal choice for erosion control applications. Plants can spread via self seeding. Cutting back the flower stems can keep the plants looking tidy and promote more compact regrowth. A sparse rebloom may occur after being cut back.

Moss Phlox is more resistant to powdery mildew than other cultivars of the same species. Some insects and rabbits may munch on the leaves.
