Leaves

The heart-shaped leaves occur on long petioles arising from the basal crown. Leaves are hairless and have a rounded, toothed margin.

Identifying Characteristics

This plant can be identified by its heart-shaped leaves, purple flowers, and rhizomes. The lowest petal on the flower is also lacking a spur, helping distinguish it from a great-spurred violet.

Flower Seed Head

The bluish purple flowers occur on leafless stalks that grow to the same height as the leaves. Each flower has 5 petals, with the lateral petals being bearded or hairy at the base.

Seed Fruit

The seeds develop in a three-parted capsule that is capable of ejecting the seeds when ripe.
