Redcurrant
The redcurrant or red currant (''Ribes rubrum'') is a member of the genus '' Ribes'' in the gooseberry family. It is native to western Europe. The species is widely cultivated and has escaped into the wild in many regions. Description ''Ribes rubrum'' is a deciduous shrub normally growing to tall, occasionally , with five-lobed leaves arranged spirally on the stems. The flowers are inconspicuous yellow-green, in pendulous racemes, maturing into bright red translucent edible berries about diameter, with 3–10 berries on each raceme. An established bush can produce of berries from mid- to late summer. Phytochemicals Redcurrant fruits are known for their tart flavor, a characteristic provided by a relatively high content of organic acids and mixed polyphenols. As many as 65 different phenolic compounds may contribute to the astringent properties of redcurrants, with these contents increasing during the last month of ripening. Twenty-five individual polyphenols and ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ribes Triste
''Ribes triste'', known as the northern redcurrant, swamp redcurrant, or wild redcurrant, is an Asian and North American shrub in the gooseberry family.

Ribes
''Ribes'' is a genus of about 200 known species of flowering plants, most of them native to the temperate regions of the Northern Hemisphere. The various species are known as currants or gooseberries, and some are cultivated for their edible fruit or as ornamental plants. ''Ribes'' is the only genus in the family Grossulariaceae. Description ''Ribes'' species are medium shrublike plants with marked diversity in strikingly diverse flowers and fruit. They have either palmately lobed or compound leaves, and some have thorns. The sepals of the flowers are larger than the petals, and fuse into a tube or saucer shape. The ovary is inferior, maturing into a berry with many seeds. Taxonomy ''Ribes'' is the single genus in the Saxifragales family Grossulariaceae. Although once included in the broader circumscription of Saxifragaceae '' sensu lato'', it is now positioned as a sister group to Saxifragaceae ''sensu stricto''.

Ribes Alpinum
''Ribes alpinum'', known as mountain currant or alpine currant, is a small deciduous, dioecious shrub native to central and northern Europe from Finland and Norway south to the Alps and Pyrenees and Caucasus, Georgia; in the south of its range, it is confined to high altitudes. It is scarce in western Europe, in Britain being confined to a small number of sites in northern England and Wales. ''R. alpinum'' grows to tall and broad, with an upright and dense shape. The bark is initially smooth and light grey, later it becomes brownish grey and eventually starts to flake off. The buds are scattered, compressed and light green to white. The leaves are palmate. The upper side of the leaves are dark green with scattered hair, while the bottom is light green. The male and female flowers are on distinct specimens. Both kinds of flowers are organized in clusters in the corners of the leaves, where the male's are the longest. The individual flowers are small and greenish-yellow. The frui ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cultivars
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in '' Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated vari ...

Albino
Albinism is the congenital absence of melanin in an animal or plant resulting in white hair, feathers, scales and skin and pink or blue eyes. Individuals with the condition are referred to as albino. Varied use and interpretation of the terms mean that written reports of albinistic animals can be difficult to verify. Albinism can reduce the survivability of an animal; for example, it has been suggested that albino alligators have an average survival span of only 24 hours due to the lack of protection from UV radiation and their lack of camouflage to avoid predators. It is a common misconception that all albino animals have characteristic pink or red eyes (resulting from the lack of pigment in the iris allowing the blood vessels of the retina to be visible), however this is not the case for some forms of albinism. Familiar albino animals include in-bred strains of laboratory animals (rats, mice and rabbits), but populations of naturally occurring albino animals exist in the w ...

White Currant
The white currant or whitecurrant is a group of cultivars of the red currant (''Ribes rubrum''), a species of flowering plant in the family Grossulariaceae, native to Europe. It is sometimes mislabelled as '' Ribes glandulosum'',Darina Allen which is the 'skunk currant' in the USA. Description It is a deciduous shrub growing to tall and broad, with palmate leaves, and masses of spherical, edible fruit (berries) in summer. The white currant differs from the red currant only in the colour and flavour of these fruits, which are a translucent white and sweeter. Cultivation Unlike their close relative the blackcurrant, red and white currants are cultivated for their ornamental value as well as their berries. Currant bushes grow best in partial to full sunlight and can be planted between November and March in well-drained, slightly neutral to acid soil. They are considered cool-climate plants and fruit better in northern areas. They can also be grown in large containers. The firm ...
