Viola cornuta, known as horned pansy[1] 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).[2] 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.[3][4]
This plant,[5] and the white-flowered Alba Group,[6] have gained the Royal Horticultural Society's Award of Garden Merit.[7]
It is a known host of the pathogenic fungus Puccinia violae.[8]
Cultivation
[edit]Viola cornuta is hardy to USDA zones 6–11[9] (hardy in the UK to −15 °C (5 °F)).[5] Many cultivars are hybrids with Viola × wittrockiana, designated as Viola × williamsii.[10] Some of these, such as 'King Henry', may be hardy to zone 4.[11]
