In New York Spurred Gentian occurs on calcareous cliffs, ledges, and outcrops in cool (often shaded) micro-climates. All of the known, extant sites in the state are along rivers (New York Natural Heritage Program 2011). Moist to wet, cool woods, bogs (Haines 1998). Cedar swamps; woods and thickets of spruce, fir, cedar, less often pine and aspen; frequently in springy, mossy places and often especially common at the borders of coniferous woods (as along shores); occasionally in fens and borrow pits (Voss 1996). Moist or wet woods and bogs (Gleason and Cronquist 1991).
