Western Blue Violet is well-suited to woodland, banks, or wild gardens where it spreads by self-seeding and creeping stems. The young leaves and flower buds can be used in salads or cooked as greens. The leaves are reported to contain more vitamin A than spinach, and one-half cup of violet leaves has as much vitamin C as four oranges. Tea can also be made from the dried leaves.
