Sweet Violet

Viola odorata

The Story

Plant Bio

Viola odorata, sweet violet, is a low evergreen perennial ground cover from Europe, forming clumping, creeping mats only 4 to 6 in high and about as wide before it runs. Dark green heart-shaped basal leaves form a rosette, sparsely haired and often wrinkled above. Solitary blue to purple flowers appear in early spring.

This is the violet grown for scent, and the perfume carries surprisingly far for so small a flower. Seeds carry an oily white appendage that ants collect and carry off, which is how colonies travel. It hosts fritillary butterfly larvae, and both leaves and flowers are edible.

Uses & Benefits:

Ornamental UsesScented purple-blue flowers in early spring above an evergreen mat of heart-shaped leaves that holds through winter.
Practical UsesA low-maintenance ground cover for shaded ground, with edible leaves and flowers used for scenting and decoration.
Ecological BenefitsSupports fritillary butterfly larvae, feeds early pollinators, and its ant-dispersed seed spreads colonies naturally.

Planting

How to Grow

  1. Choose a site in dappled or partial shade, out of hot afternoon sun.
  2. Plant into moist, humus-rich soil of almost any pH.
  3. Space plants about 8 in apart to knit into a cover.
  4. Water in well and keep moist through the first season.
  5. Mulch lightly with leaf mould in autumn.
  6. Lift and divide congested clumps every three or four years.

Pro Tip

Ants carry the seed, so colonies appear several feet from where you planted them; site it where that wandering is welcome.
