Growing notes
- Larval food plant for fritillary butterflies — the silver-washed, dark green and pearl-bordered fritillaries all depend on Viola species
- Flowers in earliest spring in deciduous woodland
- Excellent ground cover under shrubs and trees, spreads gently by seed
- Distinguish from sweet violet (V. odorata) by the lack of scent
