Appearance
"Helleborus niger" is an evergreen plant with dark leathery pedate leaves carried on stems 9–12 in tall. The large flat flowers, borne on short stems from midwinter to early spring, are white or occasionally pink.There are two subspecies: "H. niger niger" as well as "H. niger macranthus", which has larger flowers. In the wild, "H. niger niger" is generally found in mountainous areas in Switzerland, southern Germany, Austria, Slovenia, Croatia and northern Italy. "Helleborus niger macranthus" is found only in northern Italy and possibly adjoining parts of Slovenia.

Uses
"Helleborus niger" is commonly called the Christmas rose, due to an old legend that it sprouted in the snow from the tears of a young girl who had no gift to give the Christ child in Bethlehem.One subspecies blooms at the abbey in England believed by some to have been established by St. Thomas. There is a source that claims it blooms near the new calendar date of January 6. This date had been Christmas Day under the old Julian calendar. So when Christmas Day under the new calendar came around and the flower did not bloom, it was such a frightful omen that England did not adopt the Gregorian calendar at that time in 1588; adoption had to wait until 1751.
In the Middle Ages, people strewed the flowers on the floors of their homes to drive out evil influences. They blessed their animals with it and used it to ward off the power of witches. These same people believed, however, that witches employed the herb in their spells and that sorcerers tossed the powdered herb into the air around them to make themselves invisible.
In the early days of medicine, two kinds of hellebore were recognized: black hellebore, which included various species of "Helleborus", and white hellebore. "Black hellebore" was used by the ancients to
treat paralysis, gout and particularly insanity, among other diseases. "Black hellebore" is also toxic, causing tinnitus, vertigo, stupor, thirst, a feeling of suffocation, swelling of the tongue and throat, emesis and catharsis, bradycardia, and finally collapse and death from cardiac arrest. Research in the 1970s, however, showed that the roots of "H. niger" do not contain the cardiotoxic compounds helleborin, hellebrin, and helleborein that are responsible for the lethal reputation of "black hellebore". It seems that earlier studies may have used a commercial preparation containing a mixture of material from other species such as "Helleborus viridis", green hellebore.
In antiquity the most famous place for the black hellebore was the Phokian city of Antikyra in Greece.
Black hellebore was the dominant purgative of antiquity, frequently prescribed for that purpose by Hippocrates, the father of medicine, in the fifth century B.C. It was said to be introduced by Melampus, with which he healed the madness of the daughters of Proteus, king of Argos. The sedative property of hellebore was noted about one hundred years later by Theophrastus.
Cultural
The plant is a traditional cottage garden favourite because it flowers in the depths of winter. Large-flowered cultivars are available, as are pink-flowered and double-flowered selections. It has been awarded an Award of Garden Merit H4 by the Royal Horticultural Society, as has one of its hybrids.It can be difficult to grow well; acid soil is unsuitable, as are poor, dry conditions and full sun. Moist, humus-rich, alkaline soil in dappled shade is preferable. Leaf-mould can be dug in to improve heavy clay or light sandy soils; lime can be added to 'sweeten' acid soils."Helleborus niger" is commonly called the Christmas rose, due to an old legend that it sprouted in the snow from the tears of a young girl who had no gift to give the Christ child in Bethlehem.
