Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, michiganflora.net will point to this new site.
The new site offers several benefits over the existing website, including real coordinate mapping, giving a clearer view of the density of documentation as well as more precision about plant distributions and their link to landforms. We will also have the ability to update species pages more regularly, both in terms of new collections and as more existing Michigan specimens are georeferenced. In addition, we have a better photo display, and offer indented keys.

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.
