Viola cornuta ‘Clouded Yellow’
Viola cornuta ‘Clouded Yellow’ with steely grey blue over pale lemon yellow flowers in Spring and as the Summer heats up the blue dissipates until the flowers are largely all yellow. Very beautiful and richly scented. Viola cornuta ‘Clouded Yellow’ is always the earliest cornuta cultivar into flower in early April, and with a mid season chop back to 2inches and a liquid feed it will be smothered in flowers once again into late Summer and Autumn.
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).
