How to Identify

A perennial plant. It grows 15-30 cm high and 38-60 cm wide. It has underground stems or rhizomes. The leaves are oval and 25 mm long. They have shallow teeth. The flowers are 18 mm wide and violet or mauve-blue. They have broad petals and are spurred. The veins are darker and they are yellow in the centre.

How to Grow

Easily grown in any fertile soil in full sun or partial shade. Prefers a well-drained moisture-retentive soil. Tolerates sandstone and limestone soils but becomes chlorotic if the pH is too high. Prefers a pH between 6 and 6.5. A very ornamental plant, there are many named forms. If the plants are cut back after flowering they will flower again in late summer. All members of this genus have more or less edible leaves and flower buds, though those species with yellow flowers can cause diarrhoea if eaten in large quantities. This species has deep-violet flowers.

Propagation: Sow seed in autumn in a cold frame for best results, or sow stored seed in early spring in a cold frame. Prick out seedlings into individual pots once large enough to handle, then plant out during summer. Divide plants in autumn or just after flowering. Larger divisions can go directly into their permanent positions, but smaller divisions are best potted up and grown on in light shade in a greenhouse or cold frame until establishing well, then planted out in summer or the following spring.

Medicinal Uses

None known

Other Uses

Makes a useful ground cover for a cool, open situation. It requires some weeding during the first year or two but then forms an effective weed-excluding carpet. Space plants approximately 60cm apart in each direction.

Viola cornuta, known as horned pansy or horned violet, is a species of flowering plant in the violet family Violaceae, native to the Pyrenees and the Cordillera Cantábrica of northern Spain at an altitude of 1,000–2,300 metres (3,300–7,500 ft). It is a low-growing, clump-forming temperate evergreen perennial, reaching 50 cm (20 in) in height and spread. It has mid-green ovate leaves with rounded teeth, and masses of delicate pale violet flowers in early summer. The flower consists of five strap-shaped petals with a slender spur. This plant, and the white-flowered Alba Group, have gained the Royal Horticultural Society's Award of Garden Merit. It is a known host of the pathogenic fungus Puccinia violae.
