Hellebores
Commonly known as hellebores (), the Eurasian genus ''Helleborus'' consists of approximately 20 species of herbaceous or evergreen perennial flowering plants in the family Ranunculaceae, within which it gave its name to the tribe of Helleboreae. Despite names such as "winter rose", "Christmas rose" and "Lenten rose", hellebores are not closely related to the rose family (Rosaceae). Many hellebore species are poisonous. Description The flowers have five petal-like sepals surrounding a ring of small, cup-like nectaries which are actually petals modified to hold nectar. The sepals do not fall as petals would, but remain on the plant, sometimes for many months. Recent research in Spain suggests that the persistence of the sepals contributes to the development of the seeds. Taxonomy The genus was established by Carl Linnaeus in volume one of his ''Species Plantarum'' in 1753. The scientific name ''Helleborus'' could derive from the Ancient Greek word (), the common name for '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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). Taxonomy 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 the colour of the roots. There are two subspecies: ''H. niger'' subsp. ''niger'' and ''H. niger'' subsp. ''macranthus'', which has larger flowers (up to 3.75 in/9 cm across). In the wild, ''H. niger'' subsp. ''niger'' is generally found in mountainous areas in Switzerland, southern Germany, Austria, Slovenia, Croatia and northern Italy. ''Helleborus niger'' subsp. ''macranthus'' is found only in northern Italy and possibly adjoining parts of Slovenia. Description ''Helleborus niger'' is an ...

Helleborus Orientalis
''Helleborus orientalis'', the Lenten rose, is a perennial flowering plant and species of hellebore in the buttercup family, Ranunculaceae, native to Greece and Turkey. Description This perennial reaches tall, with glossy green palmate leaves composed of 7–9 leaflets with serrated leaf margins. Leathery in texture, the leaves are evergreen. The cup-shaped pendent flowers appear in late winter and spring, arising in groups of 1–4 on the ends of thick stems rising above the foliage. They have yellow stamens. All parts of the Lenten rose are poisonous. Sap coming into contact with the skin may cause temporary irritation, while ingestion of large quantities can cause burning of mouth and throat, vomiting, abdominal cramping, and diarrhea. Taxonomy Jean-Baptiste Lamarck described the species in 1789, giving it its current name of ''Helleborus orientalis'' (""). Within the genus ''Helleborus'', it has been classified in the section ''Helleborastrum'', and is closely related to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helleborus Argutifolius
''Helleborus argutifolius'', the holly-leaved hellebore, or Corsican hellebore, syn. ''H. corsicus'', ''H. lividus'' subsp. ''corsicus'' is a species of flowering plant in the family Ranunculaceae, native to Corsica and Sardinia. It is an evergreen perennial growing to tall by wide, with large leathery leaves comprising three spiny-toothed leaflets, and green bowl-shaped flowers in late winter and early spring. The Latin specific epithet ''argutifolius'' means “with sharp-toothed leaves” . In cultivation ''Helleborus argutifolius'' hybridises readily with the closely related '' H. lividus''. ''H. argutifolius'' has gained the Royal Horticultural Society's Award of Garden Merit The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS).

Helleborus Thibetanus
''Helleborus thibetanus'', the Tibetan hellebore, is a species of flowering plant in the family Ranunculaceae, native to China, in S Gansu, NW Hubei, S Shaanxi and NW Sichuan. This rhizome, rhizomatous perennial plant, perennial has a clump of smooth, finely serrated ovate leaves, which appear from early spring to midsummer. The papery, cup shaped flowers are borne in early Spring. They open white, turning pink and finally green. This hellebore prefers a moist, shaded and sheltered position in neutral or slightly alkaline soil. Like many hellebores, leaves may be attacked by leaf spot or virus; so old leaves should be removed before new growth appears. References Flora of China Helleborus, thibetanus {{Ranunculales-stub ...

Seed
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general me ...
