A violet commonly seen even by roadsides, a perennial.
It grows in woods and at woodland edges from lowlands to mountains, often forming colonies.
It has several aerial stems.
The leaves are basal with long petioles, heart-shaped, 1.5–2.5 cm long, with low serrations on the margin.
The stipules are deeply divided like the teeth of a comb.
The flowers are borne at the tips of upright flower stalks 6–10 cm long arising from among the basal leaves or from the leaf axils; they are about 2.5–3 cm across, pale purple, and face sideways.
The center of the lip petal is white with dark purple lines.
A spur extends behind the flower, and nectar collects in it.
The summer flowers are cleistogamous.
The fruit is a capsule that splits into 3 when ripe and scatters the seeds.
