Phlox is a genus of 67 species of perennial and annual plants found mostly in North America (one in Siberia) in diverse habitats from alpine tundra to open woodland and prairie. Some flower in spring, others in summer and autumn.
Flowers may be pale blue, violet, pink, bright red, or white. Many are fragrant.
Fertilized flowers typically produce one relatively large seed.
Some species such as P. paniculata (Garden Phlox) grow upright, while others such as P. subulata (Steak Phlox) grow short and matlike.
The foliage of Phlox is sometimes eaten by the larvae of some Lepidoptera species including Dot Moth, Gazoryctra wielgusi, Hummingbird Hawk-moth and Schinia indiana (which feeds exclusively on P. pilosa). Phlox species are also a popular food source for groundhogs, rabbits and deer.
