Native to the southeastern US, Phlox carolina (Carolina Phlox) is an erect, herbaceous perennial boasting broadly cylindrical clusters of lavender to pink or white flowers over a long season. Blooming profusely from late spring to mid-summer, then intermittently until frost, the fragrant flowers are rich in nectar and visited by bees, hummingbirds, and butterflies. They are borne on slender, red-streaked stems clad with bright-green, oval, and leathery leaves. The blossoms make excellent fresh-cut flowers. Resistant to powdery mildew, Carolina Phlox self-sows without being aggressive. Plant in drifts for great impact and make sure you have enough for the vase!

  • Grows up to 24-36 in. tall (60-90 cm) and 18-24 in. wide (45-60 cm). May reach 5 ft. in height (150 cm).
  • Performs best in full sun to part shade in fertile, acidic, moist, well-drained soils.
  • Excellent choice for perennial borders, city gardens, or informal gardens. May be planted as a single specimen or in groupings.
  • Keep an eye out for phlox eelworm, slugs, snails, or powdery mildew.
  • Propagate by seed, cuttings, or division.
  • Native to the southeastern US.
