Deciduous forests and forest openings, along larger rivers.
In the absence of flowers, one might confuse the upper part of specimens with the similarly pubescent Aureolaria virginica, although the latter, besides its much larger flowers, usually has slightly longer pedicels and a larger capsule (over 1 cm long, compared to 1 cm or less in D. macrophylla), and is a shorter plant; Dasistoma can be up to 2 m tall. Our other two species of Aureolaria are easily distinguished from Dasistoma by having the pubescence glandular (A. pedicularia) or absent (A. flava).
Usually considered an annual, but vegetative rosettes present at Michigan populations suggest it may sometimes be a biennial (or more likely monocarpic).
