Best grown in average, medium moisture, well-drained soil in full sun. Prefers sandy or gravelly soils. Tolerates hot, dry exposures better than most other species of phlox. Cut back stems after flowering by 1/2 to maintain form and to promote denser growth.

Noteworthy Characteristics

This creeping phlox cultivar is a stoloniferous, mat-forming perennial which forms a low ground cover to 6" tall but spreads by creeping stems to 2' wide. Loose, few-flowered clusters (3-5 flowers each) of tubular, deep pink flowers with dark throats and with five, flat, notched, petal-like lobes (to 1/2" across) cover the compact foliage mound with bloom in spring. Stiff, narrow, linear, needle-like leaves (to 1/2" long).


Phlox sublata and its cultivars do not seem to be bothered by powdery mildew as are most other species of phlox. Spider mites and rust are occasional problem.

Garden Uses

Mass in rock gardens. Ground cover for slopes and banks. Cascade over a stone wall. Edging for borders. When massed, the resulting carpet of spring bloom can be spectacular.
