Phlox paniculata (Garden Phlox)

Border Phlox, Garden Phlox, Fall Phlox, Perennial Phlox


Prized for its long-lasting floral show, Phlox paniculata (Garden Phlox) is an upright herbaceous perennial with large, pyramidal clusters, 4-8 in. wide (10-20 cm), densely packed with pink, rosy-lavender, or occasionally white flowers in early to late summer. Blooming for about 6 weeks, the fragrant flowers are rich in nectar and visited by hummingbirds and butterflies. They are borne on stout stems clad with narrow, lance-shaped, deep green leaves. Garden Phlox species has given rise to many cultivars. Highly popular, this is a garden classic that is considered by many as the backbone of summer borders. The species itself is however rarely seen in gardens. This is pitiful as it is the most mildew resistant of all. Plant in drifts for great impact and make sure you have enough for the vase!

  • Grows up to 2-4 ft. tall (60-120 cm) and 2-3 ft. wide (60-90 cm). Will self-seed in the garden.
  • Prefers full sun to very light shade and enjoys moderately fertile, medium moisture, well-drained soils. This plant needs good air circulation. Avoid overhead watering and add summer mulch to keep the root area cool.
  • Excellent choice for perennial borders where dazzling flowers are welcomed in any color scheme. May be planted as a single specimen or in groupings.
  • Keep an eye out for powdery mildew and root rot. Deer resistant.
  • Deadhead to preserve a neat appearance and promote new blooms. Cut back stems after flowering is over.
  • Propagate by stem or root cuttings, division or seed.
  • Native to the United States.
