This genus contains 67 species of annuals and perennials and belongs to the phlox family, the Polemoniacea. Annual phlox tend to be small mounding bushed; rock phlox closely hug the ground; trailing forms have long stems; and border phlox are upright and bushy. The leaves range from rounded and shiny to narrow and hairy, depending on the species. The small flowers are long-tubed, widely flared, bell-shaped, slightly fragrant, and grow in clusters of brightly colored floral sprays ranging from white and pale pink to bright pink, red, and purple. The genus name Phlox comes from the Greek word for flame. Use in bedding and border schemes.
CULTIVATION
Although all species prefer well-drained soil that can be kept moist, annual and rock phlox need full sun, while border and trailing forms will grow in part-shade. Border phlox need good ventilation to prevent mildew. Propagate from seed, by division, or from cuttings.
Top Tip
Clumps of summer phlox should be divided every 3 to 4 years. Divide carefully using a clean sharp knife, making sure that each division has a good set of roots.
