Hellebore (Lenten rose) is not a new plant to Czech and Slovak gardens. I remember those flowering stems that surprisingly pushed through the snow in late winter and I kept asking grandma how come that a plant can flower while there is still snow on the ground. These evergreen perennials are still very popular, mainly thanks to newly hybridized varieties with fantastic flowers. German nursery Heuger has been breeding Lenten roses since 1950’s. No wonder they are considered to be the top producers of these beautiful plants in Europe. Their Helleborus Gold Collection® (HGC) is a trade mark for the best inventions in the field of hybrid hellebores.

Jesko® hellebore is another creation from German breeder Josef Heuger. Its flowers are quite large: 5-8 cm across, pure white with yellow stamens in the centre, and mature to pale yellow green when the stamens have fallen off. In warm winters flowering begins just before Christmas, and continues for about 3 months, in cold winters from late winter. Evergreen leaves are leathery, palmate, and deep green and form a compact clump. Patent No. PP25316 issued in 2008.

Hellebore likes heavy, evenly moist, neutral to alkaline, rich in humus soil in dappled shade or filtered sun. This hybrid will prefer at least half a day with direct sunlight. Fertilizing will increase flowering and help the leaves remain strong and nice throughout the winter. Grow it somewhere near your house entrance or close to the window you look out of frequently so that you can enjoy the plant when it starts flowering since at that time the weather outside is not yet ideal for walking around the garden. The flowers can cheer up a number of grey and dull days of late winter therefore thumbs up for hellebore! Harmful if eaten. Hardy to about -29°C (USDA zone 5).
