This is Viola x wittrockiana, also known as Pansy Karma Blue Butterfly, Hearts Ease, Ladies Delight, and Stepmothers Flower. These beautiful pansies like to grow in full sun to partial shade and they do not mind growing in a container either if that suits your needs. Young leaves and flower buds can be eaten cooked or raw. They are also used as a garnish or as a thickener in soups. You can also use the leaves to make tea. Violas in general are larval host plants for the Great Spangled Fritillary, Meadow Fritillary, Diana Fritillary, Aphrodite Fritillary, Regal Fritillary, Zerene Fritillary, Coronis Fritillary, Callippe Fritillary, Unsilvered Fritillary, Edwards Fritillary, Hydaspe Fritillary, Arctic Fritillary, Silver-bordered Fritillary, Mormon Fritillary, Atlantis Fritillary, Pacific Fritillary, Northwestern Fritillary, and Variegated Fritillary butterflies, and for the Great Leopard, and The Beggar moth. It is also a nectar source for the Southern Rocky Mountain Orangetip, Stella Orangetip, West Virginia White, and Falcate Orangetip butterflies. This plant is grown as an annual all over but is considered a tender perennial where it can live through the Winter in USDA Hardiness Zones 7 to 10.
