This wildflower has a white to pink erect stem usually not exceeding half a meter in height which may branch several times. Deeply lobed leaves are located mostly about the base of the plant. The inflorescence occupying the top end of the stem has a few widely spaced flowers on long pedicels. The sepals are long and curl backwards or fold upon themselves. They may be dark purple to light blue or rarely white. The lower petals are the same color, while the upper are often white. The spur is one or two centimeters long.

D. nuttallianum is very poisonous to livestock, especially cattle.[1]
