A few are bicolored. Each flower is composed of an upper pair of petals, two side petals, and one lower petal. The fruit is a small capsule which splits into 3 parts at maturity. Violets have also adapted to landscape sites. They are common weeds in lawns, especially in shady areas.
Violets are difficult to control in turfgrass areas.
Probably the best way for a home gardener to control a small infestation of violets in the lawn is to dig them up. The most effective compound on wild violets is triclopyr. However, products containing triclopyr are generally unavailable to home gardeners. Gardeners who would like to control their wild violets with triclopyr should contact a professional lawn care service. Multiple applications may be needed to control wild violets.
