Helleborus niger, Linnaeus (1753)
Of all Helleborus species, Helleborus niger is probably the best known. A native to the Swiss mountains, southern Austria, Germany, Slovenia, Croatia and northern Italy, the Christmas Rose prefers lightly shaded places on deep alkaline soil that retains moisture well.
Its deep green leaves are divided into seven to nine segments and stay on the plant throughout the year. Although the tips of the segments are serrated, they are not stinging.
From November to March, this species produces pure white flowers that can take on a pink hue as they age and, at a later stage, turn green. Normally, the flowers, carried on round flower stems, reach out over the deep green leaves.
