General Description

This beloved short-lived perennial has been heavily hybridized and is a favorite cool season bedding plant. In its natural form, the horned violet is an evergreen, alpine perennial that originates from the Pyrenees Mountains in France and Spain and regions in Switzerland. It has escaped and become naturalized in other parts of Europe, particularly Scotland where commonly grows in grassy, upland meadows.

The small plant forms neat, tufted clumps of foliage that rise from small, slender rhizomes with fibrous roots. Its small, spring green leaves are oval or heart-shaped and have scalloped edges. Its delicate, five-petaled, violet-like flowers come in shades of violet-blue, lavender, purple or white. Each flower is subtly fragrant and has a small awl-shaped spur, or nectary, at its base. These are sometimes likened to a horn, which explains the common name, horned violet. The flowers are bee pollinated but may attract butterflies too. Seed-filled capsule fruits follow that split open into three parts when mature. These readily germinate if allowed to.

The horned violet blooms continuously from late spring to late summer in regions where the growing season is generally cool but will refrain from blooming as the weather heats up. Cultivated forms can be forced to bloom at other times of the year and are a favorite winter annual in the south.

Full sun and sharply drained, moderately fertile soil with a neutral pH is preferred. The horned violet is short-lived so it’s seedlings are often welcome and may even naturalize if allowed to. This ornamental is best planted in cool seasons or where summers never get too hot. It is ideal for container plantings, alpine or rock gardens, or along the edge of mixed borders.

Many cultivars listed as Viola cornuta are likely more complex hybrids.
