The genus name Viola means violet in Latin. For Nuttall's violet the only purple coloring is the nectar guides in the throat of the flower.[4] The species name is given in honor of noted botanist Thomas Nuttall.[2]
The plant is highly variable, usually with bright yellow petals. The veined, elliptical leaves are 2.5–10 centimeters (1–4 in) long.[3]
The species serves as a larval host for the Coronis fritillary butterfly.[2]
