Coefficient of Conservatism:
Coefficient of Wetness:
Moist sandy plains and shores, marshy meadows; wet prairies, fens, tamarack swamps; mucky swales, marly shores, roadsides and fields; unlike other species, rarely in drier oak or jack pine savanna. C. K. Dodge wrote on an 1896 label: “Thousands of acres covered with it about Lake St. Clair.”
This species hybridizes with L. pycnostachya. Rare individuals with scattered hairs in the inflorescence and other intermediate conditions indicate some introgression. White-flowered plants are f. albiflora Britton and have been found on Harsens Island, St. Clair Co.
This species especially (but also other Liatris) are cultivated, and some outlying northern records may be escapes from cultivation.
