Quercus × Turneri
''Quercus'' × ''turneri'' (or ''Quercus turneri''), known as Turner's oak, is a hybrid species of white oak native to Spain. It is a naturally occurring hybrid of holm oak (''Quercus ilex'') and pedunculate oak ('' Quercus robur''), found where their ranges overlap, but was first described from cultivation. A semi-evergreen tree of small to medium size with a rounded crown, it was originally raised at the Holloway Down Nursery of Spencer Turner, Leyton, Essex, UK, noted by the zoologist Jean-Baptiste Lamarck at Trianon, Versailles in 1783, as the ''chêne de turnère''. (Turner had died in January 1776, and the nursery grounds, on extended lease, returned to the landowner.) An early specimen was planted at the Royal Botanic Gardens, Kew in 1798; it was uprooted in the Great Storm of 1987 but resettled in the ground and then increased its healthy growth. Its 'Pseudoturneri' cultivar has gained the Royal Horticultural Society's Award of Garden Merit The Award of Garden Merit ...

Endemic Flora Of Spain
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus
An oak is a tree or shrub in the genus ''Quercus'' (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably '' Lithocarpus'' (stone oaks), as well as in those of unrelated species such as ''Grevillea robusta'' (silky oaks) and the Casuarinaceae (she-oaks). The genus ''Quercus'' is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America has the largest number of oak species, with approximately 160 species in Mexico of which 109 are endemic and about 90 in the United States. The second greatest area of oak diversity is China, with approximately 100 species. Description Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth margins. ...

Quercus × Hispanica
''Quercus'' × ''hispanica'', commonly known as Spanish oak, is tree in the family Fagaceae. It is a hybrid between the European trees Turkey oak (''Quercus cerris'') and cork oak (''Quercus suber''). Distribution Hybridisation occurs naturally in southwestern Europe where both parent species occur. The Lucombe oak cultivar is frequently found in British collections. To be a true Lucombe oak, cultivars must be clones of the original hybrid arising in William Lucombe's Exeter nursery. Cultivation A number of named cultivars are grown in gardens, parks, arboreta and botanical gardens. Cultivars * ''Quercus'' × ''hispanica'' 'Lucombeana' ("Lucombe oak"), originally raised by William Lucombe at his Exeter, UK nursery in 1762. An early Lucombe Oak is in Kew Gardens arboretum, and is regarded as one of their 'heritage trees'.

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 ...

White Oak
The genus ''Quercus'' contains about 500 species, some of which are listed here. The genus, as is the case with many large genera, is divided into subgenera and sections. Traditionally, the genus ''Quercus'' was divided into the two subgenera ''Cyclobalanopsis'', the ring-cupped oaks, and ''Quercus'', which included all the other sections. However, a comprehensive revision in 2017 identified different relationships. Now the genus is commonly divided into a subgenus ''Quercus'' and a sugenus ''Cerris'', with ''Cyclobalanopsis'' included in the latter. The sections of subgenus ''Quercus'' are mostly native to the New World, with the notable exception of the white oaks of sect. ''Quercus'' and the endemic Quercus pontica. In contrast, the sections of the subgenus ''Cerris'' are exclusively native to the Old World. Legend Species with evergreen foliage ("live oaks") are tagged '#'. Species in the genus have been recategorized between deciduous and evergreen on numerous occasions, alt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
