Description

Blue Phlox is a herbaceous perennial that may grow 6 to 12 inches high. The leaves are opposite with a smooth margin. Fine hairs extend from the leaf margin. The stem is both hairy and sticky. Rose, lavender or violet-blue flowers first mature in spring and continue into early summer.

Some uses in the garden include rock gardens, border fronts, wild gardens, native plant gardens or naturalized areas. It is also an effective, shallow-rooted cover for early spring bulbs.

Fire Risk: This plant has a low flammability rating.

 Seasons of Interest:

  Blooms:  Early spring/spring            Nut/Fruit/Seed:  Spring

Insects, Diseases, or Other Plant Problems: Powdery mildew can be a serious problem. Cutting back stems after flowering helps combat mildew. Spider mites can also be a problem, particularly in hot, dry conditions. Watch out for rabbits.
