"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. Helleborus niger Helleborus niger, commonly called Christmas rose or black hellebore, is an evergreen perennial flowering plant in the buttercup family, Ranunculaceae. It is poisonous. Although the flowers resemble wild roses (and despite its common name), Christmas rose does not belong to the rose family (Rosaceae). The black hellebore was described by Carl Linnaeus in volume one of his ""Species Plantarum"" in 1753. The Latin specific name ""niger"" (black) may refer to"

""Helleborus niger macranthus"" is found only in northern Italy and possibly adjoining parts of Slovenia. ""Helleborus niger"" is an evergreen plant with dark leathery pedate leaves carried on stems 9–12 in (23–30 cm) tall. The large flat flowers, borne on short stems from midwinter to early spring, are generally white, but occasionally purple or pink. The tips of the petals may be flushed pink or green, and there is a prominent central boss of yellow. The plant is a traditional"
"Helleborus viridis Helleborus viridis, commonly called green hellebore, is a perennial flowering plant in the buttercup family, Ranunculaceae, native to Central and Western Europe, including England. All parts of the plant are poisonous. The green hellebore was one of the many plants first described by Linnaeus in volume one of his 1753 tenth edition of his ""Species Plantarum"". The species name is the Latin adjective ""viridis"", ""green"". Two subspecies are recognised, subspecies ""viridis"" from Central Europe and the maritime Alps, and subspecies ""occidentalis"" from western Europe including England. Other common names recorded include bastard hellebore, bear's foot and boar's foot."

It is found wild in many parts of England, especially on limestone soil. It is an evergreen perennial growing to tall and across, with a thick succulent stem and glossy leaves. The drooping cup-shaped flowers appear in spring, and are yellowish-green, often with a purple edge to the five petal-like sepals on strongly upright stems. The flowers, typically for the"

Despite its common name, ""V. nigrum"" is not closely related to the true hellebores, nor does it resemble them. The plant was widely known even in ancient times. For example, Lucretius (ca. 99 BCE – ca. 55 BCE) and Pliny the Elder (23 AD – August 25, 79) both knew of its medicinal emetic as well as deadly toxic properties.

The species name is derived from the Latin ""oriens"" ""the east"". The common name is from their flowering during Lent. Within the genus it has been classified in the section ""Helleborastrum"", and is closely related to the other eight species. These species are all highly variable and hybridise with each other freely. The lenten rose grows as a"
