Violets are members of the family Violaceae. Most of the 4-500 species are found in the Northern Hemisphere. The flowers are usually heart-shaped and asymmetrical. You can identify many of the species by the shape of the petals. Although the colors among the violets vary (purple, blue, yellow, cream, white), the blue violet is common throughout the United States. The flowers generally bloom in the spring, but can last throughout the summer months. Most violets are fairly small plants, but some can be the size of a bush.
Violets thrive in full sun/partial shaded areas and grow best in fertile, moist soils with good drainage.
Wild violets can be difficult to manage in fescue yards. Triclopyr has been found to be an effective weed killer on violets that are otherwise hard to kill.
