Deciduous forests, often on dry to moist banks and ravines.
Typical plants of this species have the flowers regular or nearly so, and the petioles glabrous to very sparsely hirsute. Most of our plants unfortunately approach H. richardsonii in a tendency to bilaterally symmetrical flowers and very hirsute petioles, and are referred to var. hirsuticaulis (Wheelock) Rosend., Butters & Lakela. They presumably reflect the influence of hybridization in the past, and the lines between varieties, as well as species, are difficult to draw.
