Common blue violet is a rhizomatous herbaceous perennial in the violet family (Violaceae) native to eastern and central North America. It grows in woods, thickets, and along streambeds, especially in shadier areas.

The common blue violet prefers moist, rich soils and dappled sunlight. However, it will grow in many light conditions and tolerate wet soil, clay soil, and the exudates of black walnut trees. It also freely self-seeds and may become weedy in fertile, moist locations. During hot summer months, the foliage tends to deteriorate.

Host plant for the Fritillary butterflies. Early nectar support for native bees.
