North America has 60 species of wild violets (Viola), which grow in every region of the country except the Rocky Mountains. Wild violets are the perfect choice for the gardener needing to fill a shady area in the landscape. Depending on the region, wild violets range in color from various shades of purple, white, yellow and a mix of two. Wild violets range in size from the 18-inch-tall white Canada violet to the 5-inch white-and-lavender Beckwith's violet. Gardeners will find wild violets a hardy and relatively maintenance-free plant to grow.
Select an area in your garden that is shady or receives less than three hours of sunlight each day. Use wild violets under a tree, by a water garden or pond, or as ground cover.
Rid the planting area of weeds, grass or other vegetation. Do not plant the violets in an area where it will have to compete with other plants. Wait two weeks before planting the wild violets, if you use a herbicide product to kill the vegetation.
Amend the planting site with rich organic materials. Work manure, compost or peat moss into the existing soil in the planting site, as well as a foot around it. Wild violets spread by underground rhizomes and prefer rich soil.
Dig a hole that is the size of the wild violet's roots, but is no deeper. Place the plant into the hole at the same height it was originally growing and pack the dirt firmly around its base. Water the wild violet.
Apply a layer of mulch around the planting site to help the soil and wild violet's root system retain moisture. Water the wild violet again. Regularly keep the soil moist, but not soggy. Do not grow violets in dry conditions.
Fertilize the wild violet every two to three weeks with a 20-20-20 water-soluble fertilizer. Apply an application of compost in the early spring to help the wild violet obtain its optimum level of growth.
