Cardamine maxima is a species of flowering plant in the mustard family Brassicaceae.
Taxonomy.
"Cardamine maxima" was first described as "Dentaria maxima" by the English botanist Thomas Nuttall in 1818. The American botanist Alphonso Wood placed "Dentaria maxima" Nutt. in genus "Cardamine" in 1870. The name "Cardamine maxima" (Nutt.) Alph.Wood is widely used today.
"Cardamine maxima" is a member of the "Cardamine concatenata" alliance, a monophyletic group of eastern North American species that includes "Cardamine angustata", "Cardamine concatenata", "Cardamine diphylla", "Cardamine dissecta", "Cardamine incisa", and "Cardamine maxima". All members of the alliance were previously placed in genus "Dentaria" Tourn. ex L., which is now considered to be a synonym for "Cardamine" L.

In the United States, its distribution is centered in New York and western New England (Connecticut, Massachusetts, Vermont).

The global conservation status of "Cardamine maxima" is secure (G5). However, outside of New York (its center of distribution) it is uncommon (S3) at best.
