The inflorescence is a raceme of pink or white flowers each up to 1.6 centimeters long. Blooming occurs in August through October. [1] The flowers are visited by bees. [4] However, each flower is open for only a few hours and it may pollinate itself. [3] This plant is similar to and difficult to distinguish from several other Agalinis. [1]

[3] It is associated with other plants such as Agalinis purpurea , Aletris farinosa , Andropogon gerardi , Aster ptarmicoides , Calopogon tuberosus , Liatris spicata , Lobelia kalmii , Pycnanthemum virginianum , and Solidago ohioensis [3] The plant often grows in habitat maintained by a regime of periodic wildfire. [1] Fire suppression is a threat to it. [3]
