Coefficient of Conservatism:
Coefficient of Wetness:
Meadows, moist prairies, and moist shores; wet slopes and banks; ditches, moist old fields and roadsides; usually on calcareous sands and gravels; sometimes in drier, sandier settings than G. virgata.
Depauperate plants may be confused with G. virgata, for the species are not as clearly separable as one might wish (and are considered to hybridize in some regions). Indeed, some of the northernmost records mapped (some collections from Alpena, Arenac, Clare, Gladwin, Grand Traverse, Lake, Montmorency, and Roscommon Cos.) are based on specimens with rather small, ambiguous and unusually shaped leaves, though not as linear as expected (especially on small individuals) in G. virgata. The only Upper Peninsula record, reported by Lammers (2016), is a robust, typical plant.
