Violet Biology and Management in Turf1

Darcy E. P. Telenko, Barry J. Brecke, Ramon Leon, and J. Bryan Unruh2

Violets (Viola spp.) are diverse winter annuals and perennials. Perennials form rhizomes or long stolons. Many have heart-shaped leaves on long petioles and have a rosette growth habit. Some have linear leaves and others have palmate leaves. Flowers are generally purple, but can be white, pink or yellow. They reproduce by seed or, when produced, rhizomes.
