Hydrangea Serrata
''Hydrangea serrata'' is a species of flowering plant in the family Hydrangeaceae, native to mountainous regions of Korea and Japan. Common names include mountain hydrangea and tea of heaven. Growing to tall and broad, it is a deciduous shrub with oval leaves and panicles of blue and pink flowers in summer and autumn (fall). It is widely cultivated as an attractive ornamental shrub throughout the world in areas with suitable climate and soil. Taxonomy Considerable difficulties exist in the nomenclature for ''H. serrata'' and closely associated hydrangeas. It is treated here as an individual species in accordance with van Gelderen and van Gelderen.C.J. van Gelderen; D.M. van Gelderen. 2004. Encyclopedia of Hydrangeas. Timber Press. 280 p. Many botanists, however, view it as no more than a subspecies of '' H. macrophylla''. Characteristics ''Hydrangea serrata'' is similar to ''H. macrophylla'' except it is a smaller more compact shrub with smaller flowers and leaves; it is also ...

Carl Peter Thunberg
Carl Peter Thunberg, also known as Karl Peter von Thunberg, Carl Pehr Thunberg, or Carl Per Thunberg (11 November 1743 – 8 August 1828), was a Swedish naturalist and an "apostle" of Carl Linnaeus. After studying under Linnaeus at Uppsala University, he spent seven years travelling in southern Africa and Asia, collecting and describing many plants and animals new to European science, and observing local cultures. He has been called "the father of South African botany", "pioneer of Occidental Medicine in Japan", and the "Japanese Linnaeus". Early life Thunberg was born and grew up in Jönköping, Sweden. At the age of 18, he entered Uppsala University where he was taught by Carl Linnaeus, regarded as the "father of modern taxonomy". Thunberg graduated in 1767 after 6 years of studying. To deepen his knowledge in botany, medicine and natural history, he was encouraged by Linnaeus in 1770 to travel to Paris and Amsterdam. In Amsterdam and Leiden Thunberg met the Dutch botanist ...

Bacterial Wilt
Bacterial wilt is a complex of diseases that occur in plants such as Cucurbitaceae and Solanaceae (tomato, common bean, etc.) and are caused by the pathogens ''Erwinia tracheiphila'', a gram-negative bacterium, or '' Curtobacterium flaccumfaciens pv. flaccumfaciens'', a gram-positive bacterium. Cucumber and muskmelon plants are most susceptible, but squash, pumpkins, and gourds may also become infected. Bacterial wilts of tomato, ''Capsicum'' (pepper), '' Solanum ovigerum'' (eggplant), and Irish potato can be caused by (Burkholderiaceae) ''Ralstonia solanacearum''. Other bacteria in the family Burkholderiaceae can cause bacterial wilt of carnation. Bacteria in the genus ''Xanthomonas'' can cause banana bacterial wilt or bacterial wilt in the genus '' Agrostis''. Disease transmission ''Erwinia tracheiphila'' is spread between plants by two species of insect vectors, striped cucumber beetles (''Acalymma vittatum'') and spotted cucumber beetles (''Diabrotica undecimpunctata''). ...

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] |
Hydrangea
''Hydrangea'', () commonly named the hortensia, is a genus of over 75 species of flowering plants native to Asia and the Americas. By far the greatest species diversity is in eastern Asia, notably China, Korea, and Japan. Most are shrubs tall, but some are small trees, and others lianas reaching up to by climbing up trees. They can be either deciduous or evergreen, though the widely cultivated temperate species are all deciduous. ''Hydrangea'' is derived from Greek and means ‘water vessel’ (from ''húdōr'' "water" + ''ángos'' or ''angeîon'' "vessel"), in reference to the shape of its seed capsules. The earlier name, ''Hortensia'', is a Latinised version of the French given name Hortense, honoring French astronomer and mathematician Nicole-Reine Hortense Lepaute. This claim is disputed in page 88 on citation 10 at Nicole-Reine Hortense Lepaute page, which says: "Larousse considers this an injustice, and remarks that it has led many persons to the erroneous notion tha ...

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 ...

Cultivars
A cultivar is a type of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and when Plant propagation, propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human genetic engineering, 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, 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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aphids
Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white woolly aphids. A typical life cycle involves flightless females giving live birth to female nymphs—who may also be already pregnant, an adaptation scientists call telescoping generations—without the involvement of males. Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Winged females may develop later in the season, allowing the insects to colonize new plants. In temperate regions, a phase of sexual reproduction occurs in the autumn, with the insects often overwintering as eggs. The life cycle of some species involves an alternation between two species of host plants, for example between an annual crop and a woody plant. Some species feed on only one type of plant, while others are generalists, coloni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
