Farfugium Japonicum
''Farfugium japonicum'' ( syn. '' Ligularia tussilaginea'') is a species of flowering plant in the family Asteraceae, also known as leopard plant, green leopard plant or tractor seat plant. It is native to streams and seashores of Japan, where it is called ''tsuwabuki'' (石蕗). Description It is a rhizomatous evergreen perennial, growing in a loose clump about tall and wide, with large round or kidney-shaped leaves that are slightly fleshy in texture. Daisy-like yellow flowers, across, are borne in loose clusters in autumn and winter. Cultivation ''Farfugium japonicum'' is grown as an ornamental plant for garden planting and containers. The variegated cultivars are often used to brighten shade garden settings. ''Farfugium japonicum'' var. ''giganteum'' is a very large leaved selection. Some cultivars have shiny green leaves variegated with irregular creamy white or yellow markings, which are leathery and large, 4-10 in (10.2-25.4 cm) across, with wavy or toothed margins, ...

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 collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flower Pot
A flowerpot, planter, planterette or plant pot, is a container in which flowers and other plants are cultivated and displayed. Historically, and still to a significant extent today, they are made from plain terracotta with no ceramic glaze, with a round shape, tapering inwards. Flowerpots are now often also made from plastic, metal, wood, Rock (geology), stone, or sometimes biodegradable material. An example of biodegradable pots are ones made of heavy kraft paper, brown paper, cardboard, or sphagnum, peat moss in which young plants for transplanting are grown. For seedling starting in commercial greenhouses or polytunnels, pots usually take the form of trays with cells, each cell acting as one small pot. These trays are often called flats. There are usually holes in the bottom of pots, to allow excess water to flow out, sometimes to a saucer that is placed under the flowerpot. The plant can use this water with its roots, as needed. Recently, some flowerpots have been made wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garden Plants Of Asia
A garden is a planned space, usually outdoors, set aside for the cultivation, display, and enjoyment of plants and other forms of nature. The single feature identifying even the wildest wild garden is ''control''. The garden can incorporate both natural and artificial materials. Gardens often have design features including statuary, follies, pergolas, trellises, stumperies, dry creek beds, and water features such as fountains, ponds (with or without fish), waterfalls or creeks. Some gardens are for ornamental purposes only, while others also produce food crops, sometimes in separate areas, or sometimes intermixed with the ornamental plants. Food-producing gardens are distinguished from farms by their smaller scale, more labor-intensive methods, and their purpose (enjoyment of a hobby or self-sustenance rather than producing for sale, as in a market garden). Flower gardens combine plants of different heights, colors, textures, and fragrances to create interest and delight the s ...

Flora Of Japan
The flora of Japan comprises a large assemblage of plant species which can be found in Japan, such as sakura, katsura, momiji and azalea. There are many species which are endemic to Japan. Diversity Japan has significant diversity in flora. Of approximately 5,600 total vascular plant species, almost 40% are endemic. This richness is due to the significant variation in latitude and altitude across the country, a diversity of climatic conditions due to monsoons, and multiple geohistorical incidences of connections with the mainland. Vegetation types Japan consists of roughly 4 vegetation zones that are delineated by temperature and precipitation: the alpine region, subalpine region, summer-green broad-leaved forest region and evergreen broad-leaved forest region. Due to its substantial length of over 3,000 km from north to south and its mountain ranges that can exceed 3,000 meters, Japan's vegetation varies by latitude and by altitude. Evergreen forests tend to appear in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Senecioneae
Senecioneae is the largest tribe of the Asteraceae, or the sunflower family, comprising over 150 genera and over 3,500 species. Almost one-third of the species in this tribe are placed in the genus ''Senecio''. Its members exhibit probably the widest possible range of form to be found in the entire plant kingdom, and include annuals, minute creeping alpines, herbaceous and evergreen perennials, shrubs, climbers, succulents, trees, and semi-aquatic plants. Plants in this tribe are responsible for more livestock poisonings than all other plants combined. Its members usually contain liver and kidney toxic and carcinogenic unsaturated pyrrolizidine alkaloids in ''Senecio'' and furanoeremophilanes in ''Tetradymia''. A number of species are well known in horticulture. Classification Since the time of Bentham, the "premier systematic botanist of the nineteenth century", considerable efforts have been made to classify and understand the striking morphological diversity in the Se ...

Journal Of Natural Products
The ''Journal of Natural Products'' is a monthly peer-reviewed scientific journal covering all aspects of research on the chemistry and/or biochemistry of naturally occurring compounds. It is co-published by the American Society of Pharmacognosy and the American Chemical Society. The editor-in-chief is Philip J. Proteau (Oregon State University). History The journal was established in 1938 as ''Lloydia'', published by the Lloyd Library and Museum, and obtained its present title in 1979. It has been the official journal of the American Society of Pharmacognosy since 1961. Originally a quarterly publication, it became a bimonthly journal in 1975, and has appeared monthly since 1992. The American Society of Pharmacognosy began to co-publish the journal with the American Chemical Society in 1996. In 2008, the journal was hijacked by a low-quality open access journal using the same title. , this counterfeit journal was still active. Abstracting and indexing The journal is abstracted a ...

Pyrrolizidine Alkaloids
Pyrrolizidine alkaloids (PAs), sometimes referred to as necine bases, are a group of naturally occurring alkaloids based on the structure of pyrrolizidine. Pyrrolizidine alkaloids are produced by plants as a defense mechanism against insect herbivores. More than 660 PAs and PA N-oxides have been identified in over 6,000 plants, and about half of them exhibit hepatotoxicity. They are found frequently in plants in the Boraginaceae, Asteraceae, Orchidaceae and Fabaceae families; less frequently in the Convolvulaceae and Poaceae, and in at least one species in the Lamiaceae. It has been estimated that 3% of the world’s flowering plants contain pyrrolizidine alkaloids. Honey can contain pyrrolizidine alkaloids, as can grains, milk, offal and eggs. To date (2011), there is no international regulation of PAs in food, unlike those for herbs and medicines. Unsaturated pyrrolizidine alkaloids are hepatotoxic, that is, damaging to the liver. PAs also cause hepatic veno-occlusive disea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tumorigenic
Carcinogenesis, also called oncogenesis or tumorigenesis, is the formation of a cancer, whereby normal cells are transformed into cancer cells. The process is characterized by changes at the cellular, genetic, and epigenetic levels and abnormal cell division. Cell division is a physiological process that occurs in almost all tissues and under a variety of circumstances. Normally, the balance between proliferation and programmed cell death, in the form of apoptosis, is maintained to ensure the integrity of tissues and organs. According to the prevailing accepted theory of carcinogenesis, the somatic mutation theory, mutations in DNA and epimutations that lead to cancer disrupt these orderly processes by interfering with the programming regulating the processes, upsetting the normal balance between proliferation and cell death. This results in uncontrolled cell division and the evolution of those cells by natural selection in the body. Only certain mutations lead to cancer wh ...

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). It is based on assessment of the plants' performance under UK growing conditions. History The Award of Garden Merit is a mark of quality awarded, since 1922, to garden plants (including trees, vegetables and decorative plants) by the United Kingdom, Royal Horticultural Society (RHS). Awards are made annually after plant trials intended to judge the plants' performance under UK growing conditions. Trials may last for one or more years, depending on the type of plant being analyzed, and may be performed at Royal Horticulture Society Garden in Wisley and other gardens or after observation of plants in specialist collections. Trial reports are made available as booklets and on the website. Awards are reviewed annually in case plants have become unavailable horticulturally, or have been superseded by better cultivars. Similar awards The award should not be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Horticultural Society
The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity. The RHS promotes horticulture through its five gardens at Wisley (Surrey), Hyde Hall (Essex), Harlow Carr (North Yorkshire), Rosemoor (Devon) and Bridgewater (Greater Manchester); flower shows including the Chelsea Flower Show, Hampton Court Palace Flower Show, Tatton Park Flower Show and Cardiff Flower Show; community gardening schemes; Britain in Bloom and a vast educational programme. It also supports training for professional and amateur gardeners. the president was Keith Weed and the director general was Sue Biggs CBE. History Founders The creation of a British horticultural society was suggested by John Wedgwood (son of Josiah Wedgwood) in 1800. His aims were fairly modest: he wanted to hold regular meetings, allowing the society's members the opportunity to present papers on their horticultural activities and discoveries, to enc ...

Cultivar
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 variety ...

Ornamental Plant
Ornamental plants or garden plants are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost any types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents. aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and foliage plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, which is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
