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. Still, as an oriental hellebore hybrid there is some variability and plants of the same variety may slightly vary in colour depth and design.
Description of the plant:
Double Slaty Blue is a hellebore variety for lovers of dark colours. Its double flowers exhibit a very deep shade of burgundy red colour with blue hues that show especially on a cloudy day. Long stamens with creamy white anthers beautifully contrast with the petal colour. Flowers come out according to weather, mostly from February until late April atop 30-35 cm tall, upright stems. Evergreen leaves are leathery, palmate, and deep green and form a compact clump. 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).
