Horned Violet

Viola cornuta (vy-OH-la kor-NOO-tuh)

Family: Violaceae Unknown Groundcover (<1 ft)

Native to the Pyrenees, the horned violet is an evergreen herbaceous perennial often used as a bedding plant. It is a member of the violet family (Violaceae). The species epithet is Latin for “horned” and was not explained by the author. It may reference the two uppermost, narrow petals on the flower that are reminiscent of horns, or it may refer to the narrow, straight nectar spur that projects from the back of the flower. They grow best in humusy, moist, well-drained soils in full sun to part shade. They tend to bloom during cooler weather and stop during the heat of summer. An extended period of hot weather can bring on a decline in flowering. Cut the plants back to create the possibility of another bloom when temperatures decline. Deadheading can also trigger new buds to appear. Horned violets typically grow as perennials; however, they can also be grown as annuals. They spread by creeping, ascending stems to 12 inches long. Blooming in the spring, horned violets make great companion plants for tulips. Flowers of the species are blue, violet or lavender, sometimes two-toned. Many cultivars (more accurately, hybrids with other species) extend the color palette. These can include red, white, yellow and apricot. Growing in a bed may require weeding until the plants become more established. Once that occurs, they will be an effective cover that weeds may find difficult to penetrate. Use horned violet in woodland, rock, butterfly, pollinator, winter or children’s gardens. They work well as bedding, borders and ground cover. Insects, Diseases, and Other Plant Problems: Snails and slugs may affect this plant, as well as fungal leaf diseases.
