Cardamine bulbosa (Muhl.) Britton, Sterns & Poggenb.
Coefficient of Conservatism: 4
Coefficient of Wetness: -5
Wetness Index: OBL
Physiognomy: Nt P-Forb

Wet hollows and streamsides in deciduous forests (occasionally even with cedar or tamarack), swamps, springy places, sometimes in wet ditches. In the same place and season, C. douglassii blooms ca. 1–4 weeks earlier than C. bulbosa, usually beginning in mid-or late April, whereas C. bulbosa usually does not begin until mid- or even late May. Cardamine douglassii tends to be a shorter plant (especially measured to the lowest pedicel), is less often branched, and grows on the average in slightly drier places, although the two may grow together.
