DistributionNearly statewide, but absent to scarce near the coast.

This is a widespread Central and Eastern species, found from NY and SD south to northern FL and central TX.
AbundanceCommon to very common over the state, except rare to uncommon in the southern Coastal Plain and near the coast. Seemingly absent from most far eastern counties.
HabitatThis is the only native violet that occurs in ruderal habitats almost exclusively. It grows in fields, roadsides, vacant lots, and lawns, though it can grow in open woods and barrens.

PhenologyBlooms from March to May, and fruits shortly after flowering.
IdentificationThis is a very familiar roadside plant, appearing to be an exotic species, though certainly a native one. This violet is erect and has leaves coming of the stem and branches (i.e., caulescent). The leaves are on long petioles and with a rounded to ovate blade, each blade only about 1/4-1/3" long and across. The numerous flowers are on long stalks and are light blue to medium blue, with a whitish center, barely 1/3-1/2" across. The species can grow in large patches on lawns and roadsides.
Taxonomic CommentsThe species was generally known as V. rafinesquii.

General note on Viola: In 2009-10 B.A. Sorrie (website map editor) went through the whole collection at NCU, annotating all specimens against those verified by experts in the genus. The range maps in RAB (1968) have been changed accordingly. More recently, H. Ballard and students are in the process of revising all Southeastern Viola, and they will recognize more species than are listed on this website, which follows Weakley (2018).
