Viola cornuta Columbine

Viola cornuta 'Columbine' or Horned Violet is an easy, low-growing perennial with abundant and long-lasting flowering. Its numerous flowers bloom from April to September, brightening borders and balconies with their beautiful marbled petals. Against a white background, there are striking blue streaks ranging in intensity from lavender to indigo. Place it in partial shade or non-scorching sunlight and in moist and rich soil, and it will thrive.

The Columbine Viola is a spreading perennial that grows to a height and width of 15 to 20 cm (6 to 8in). It forms a base of oval, slightly toothed leaves with a dense, glossy green colour that remain throughout the winter. From this base emerge upright but flexible and delicate stems. At the top of these stems are pretty little flowers measuring 2 to 3 cm (1in). They have 5 petals: 2 overlap at the top, 2 spread out laterally, and the last one completes the bottom with sometimes a small 'dimple on the chin'. They are decorated with multiple blue marbling that stands out against their white background, ranging in intensity from lavender to indigo. A small yellow heart adds a final touch of cheerfulness.

This perennial, although not exceptionally long-lived, self-seeds spontaneously and can withstand cold weather. It prefers ordinary, not too dry soil and can tolerate some sunlight. It will thrive at the front of borders, between paving stones in a pathway, or on a damp rockery.

Viola cornuta 'Columbine' is the perfect companion for spring bulbs in pots and containers. Its range of blues contrasts beautifully with the yellow of daffodils and complements that of grape hyacinths. It extends the flowering season and provides blooms until early autumn. In borders, it lines pathways and captivates passersby with its varied patterns.
