Phlox carolina (Carolina Phlox)

Carolina Phlox, Summer Phlox, Thickleaf Phlox, Giant Phlox


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 of 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.
