Garden Marguerite
Garden marguerites, also known as marguerite daisies, are cultivars of plants in the subtribe Glebionidinae of the family Asteraceae, the great majority being hybrids created in cultivation. One of the genera belonging to the subtribe, ''Argyranthemum'', was introduced into cultivation from the Canary Islands in the 18th century, and modern cultivars are mostly sold and grown under the genus name ''Argyranthemum'' or the species name ''Argyranthemum frutescens'', although many are actually intergeneric hybrids. The first such hybrids involved species now placed in the genus ''Glebionis'', but other crosses within the subtribe are known. Breeding has aimed at introducing flower heads in varied colours and shapes while retaining the shrubby habit of ''Argyranthemum''. Garden marguerites are used as summer bedding or grown in containers. Most are only half-hardy. They can be trained into shapes such as pyramids or grown as standards.

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

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 ...

Genetic Marker
A genetic marker is a gene or DNA sequence with a known location on a chromosome that can be used to identify individuals or species. It can be described as a variation (which may arise due to mutation or alteration in the genomic loci) that can be observed. A genetic marker may be a short DNA sequence, such as a sequence surrounding a single base-pair change ( single nucleotide polymorphism, SNP), or a long one, like minisatellites. Background For many years, gene mapping was limited to identifying organisms by traditional phenotypes markers. This included genes that encoded easily observable characteristics such as blood types or seed shapes. The insufficient number of these types of characteristics in several organisms limited the mapping efforts that could be done. This prompted the development of gene markers which could identify genetic characteristics that are not readily observable in organisms (such as protein variation). Types Some commonly used types of genetic markers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysanthemum
Chrysanthemums (), sometimes called mums or chrysanths, are flowering plants of the genus ''Chrysanthemum'' in the family Asteraceae. They are native to East Asia and northeastern Europe. Most species originate from East Asia and the center of diversity is in China.Liu, P. L., et al. (2012)Phylogeny of the genus ''Chrysanthemum'' L.: Evidence from single-copy nuclear gene and chloroplast DNA sequences.''PLOS One'' 7(11), e48970. . Countless horticultural varieties and cultivars exist. Description The genus ''Chrysanthemum'' are perennial herbaceous flowering plants, sometimes subshrubs. The leaves are alternate, divided into leaflets and may be pinnatisect, lobed, or serrate (toothed) but rarely entire. The compound inflorescence is an array of several flower heads, or sometimes a solitary head. The head has a base covered in layers of phyllaries. The simple row of ray florets is white, yellow, or red. The disc florets are yellow. Pollen grains are approximately 34 mic ...

National Plant Collection
The National Plant Collection scheme is the main conservation biology, conservation vehicle whereby the Plant Heritage charity (formerly the National Council for the Conservation of Plants and Gardens) can accomplish its mission: to conserve, grow, propagate, document and make available the resource of garden plants that exists in the United Kingdom. With the National Plant Collections, individuals or organisations undertake to document, develop, and preserve a comprehensive collection of one group of plants in trust for the future. Most of the collections are composed of a related group, for example, a collection of oaks or daffodils. This allows the scheme to develop systematic coverage of cultivated plants in the United Kingdom. A few National Collections are of plants introduced by a prolific nursery or plant hunter; for example, the Sir Harold Hillier Gardens and Arboretum hold a collection of Harold Hillier, Hillier's introductions. Collection holders voluntarily subscrib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Oxford Botanic Garden
The University of Oxford Botanic Garden is the oldest botanic garden in Great Britain and one of the oldest scientific gardens in the world. The garden was founded in 1621 as a physic garden growing plants for medicinal research. Today it contains over 5,000 different plant species on . It is one of the most diverse yet compact collections of plants in the world and includes representatives from over 90% of the higher plant families. Professor Simon Hiscock became Director of Oxford Botanic Garden in 2015. History Foundation In 1621, Henry Danvers, 1st Earl of Danby, contributed £5,000 (in excess of £5,000,000 in 2018) to set up a physic garden for "the glorification of the works of God and for the furtherance of learning". He chose a site on the banks of the River Cherwell at the northeast corner of Christ Church Meadow, belonging to Magdalen College. Part of the land had been a Jewish cemetery until the Jews were expelled from Oxford (and the rest of England) in 1290. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chelsea Physic Garden
The Chelsea Physic Garden was established as the Apothecaries' Garden in London, England, in 1673 by the Worshipful Society of Apothecaries to grow plants to be used as medicines. This four acre physic garden, the term here referring to the science of healing, is among the oldest botanical gardens in Britain, after the University of Oxford Botanic Garden. Its rock garden is the oldest in Europe devoted to alpine plants and Mediterranean plants. The largest fruiting olive tree in Britain is there, protected by the garden's heat-trapping high brick walls, along with what is doubtless the world's northernmost grapefruit growing outdoors. Jealously guarded during the tenure of the Worshipful Society of Apothecaries, the garden became a registered charity in 1983 and was opened to the general public for the first time. The garden is a member of the London Museums of Health & Medicine. It is also Grade I listed in the Register of Historic Parks and Gardens of Special Historic Intere ...
