Hellebore winter hardiness

Helleborus L.

The winter hardiness of hellebore is determined by its ability to withstand temperatures down to -29…-35°С. This indicator is a species- and variety-specific trait that determines the plant's suitability for specific climatic conditions.

In the reference 9 varieties crop Christmas Rose, where this is mentioned in the description.

Winter hardiness in representatives of the genus Helleborus L. is described through the plants' ability to withstand certain minimum temperatures without the use of specialized laboratory evaluation methods. A key example of high resistance to low temperatures is the Lenten rose (Helleborus orientalis).

The practical winter hardiness of the crop depends on external agrotechnical factors, including the presence of a protective snow cover and the intensity of winter winds. Successful overwintering is also directly related to the timing of autumn planting, which allows the plants to take root before the soil freezes.
