Viola cornuta ‘Pat Kavanagh’
Viola cornuta ‘Pat Kavanagh’ is a very fine form of Viola cornuta with beautiful pale lemon yellow flowers suffused with mauve at the edges and has attractive dark rays. It holds its flowers high above neat mounds of foliage. I tend to think the habit of Viola cornuta ‘Pat Kavangh’ makes it better suited to pots then the border. Not as vigorous as some but a potful in flower is a truly beautiful.
Viola cornuta is a species native to the mountain pasturelands of the Pyrenees and is known for being hardy and robust. The flower shape is distinct and attractive, with narrow petals and a long thin upward pointing spur at the back which gives it the common name of the Horned pansy. They are particularly good for ground cover and work well scrambling through border fronts or underplanting roses. Flowering for most Viola cornuta cultivars starts in May and continues through to September. Though they tolerate a wide range of conditions, they are happiest in humus rich soils with reasonable drainage, in sun or partial shade (avoiding the hottest areas of the garden – they don’t like to be baked). Give plants space in a border to get established. We recommend planting in groups of three to achieve a good sized clump of 20-40cm in height and 30-50cm diameter (depending on cultivar).
