It is endemic to Alabama in the United States and historic to nine counties (Autauga, Bibb, Butler, Jackson, Jefferson, Lawrence, Shelby, Tuscaloosa, and Walker) Some occurrences are greatly diminished in size or extirpated, others have not been officially surveyed since the 1980s.

[3] The plant was collected in Walker County by Weezie Smith for Dr. Wherry prior to the publication of his book, The Genus Phlox, in 1955, which details the taxa.

The showy, compact flowers bloom in May and June in a color spectrum from bright pink, delicate rose to soft peach and occasionally white.

Stem leaves are opposite in placement, elliptic to oblong in shape, glabrous, with entire margins and have short, clasping petioles or are sessile.

[2] Alabama phlox occurs on roadsides and within forests openings with mixed pines, oak, hickory, vaccinium and hydrangea and on also on powerline right of ways.
