Common blue violet (Viola sororia) is a short perennial weed (less than 6 inches tall) with heart-shaped leaves on long stems growing from a crown. Plants, which grow in clumps, are spread by seed and short, thick rhizomes. While common in moist areas, plants also tolerate dry sites once established.

  • Managing with herbicides is difficult.
  • Cultivation spreads rhizomes.
  • In small plantings, dig up individual clumps.
  • Crop rotation is effective if rotational crop has more herbicide options.
