Amelanchier × Lamarckii
''Amelanchier × lamarckii'', also called juneberry, serviceberry or shadbush, is a large deciduous flowering shrub or small tree in the family Rosaceae. Description In spring the plant unfurls new leaves and produces star-shaped white flowers. The leaves are pink when they first open, maturing to yellow-green, and turn red in autumn. The plant's young berry-like pome fruits are dark red when young, but become dark purple when ripe. Taxonomy This form is a natural hybrid of ''A. arborea'' × ''A. laevis''. ('' A. laevis'' and either '' A. arborea'' or '' A. canadensis''); therefore under the rules of botanical nomenclature, it would be known as ''Amelanchier'' × ''lamarckii''. The Latin specific epithet honors the French naturalist Jean-Baptiste Lamarck (1744–1829). The European common name snowy mespilus (a name which is also attached to the related '' A. ovalis'') reflects its close relationship with the medlar genus, ''Mespilus''. It is also known a ...

Deciduous
In the fields of horticulture and botany, the term deciduous () means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed Leaf, leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of deciduous in the botanical sense is evergreen. Generally, the term "deciduous" means "the dropping of a part that is no longer needed or useful" and the "falling away after its purpose is finished". In plants, it is the result of natural processes. "Deciduous" has a similar meaning when referring to animal parts, such as deciduous antlers in deer, deciduous teeth (baby teeth) in some mammals (including humans); or decidua, the uterine lining that sheds off after birth. Botany In botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their Leaf, leaves for part of the year. This process is called abscission. I ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is often based in Latin. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including s ...

Award Of Garden Merit
The Award of Garden Merit (AGM) is a long-established award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. It includes the full range of cultivated plants, from annuals, biennials and perennials to shrubs and trees. It covers plants grown for specific purposes - such as vegetable crops, fruit, hedging, topiary, groundcover, summer bedding, houseplants, etc. It tests characteristics such as robustness, hardiness, longevity, flowering/fruiting abundance and quality, usefulness, and ease of cultivation. It pays particular attention to a plant's ability to survive and thrive in challenging conditions such as wind and frost. The AGM trophy symbol is widely used in gardening literature as a sign of exceptional quality, and is recognised as such by writers, horticulturalists, nurseries, and everybody in the UK who practises gardening.

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 Clare Matterson 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 discov ...

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 all 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 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Escaped Plant
An escaped plant is a Cultigen, cultivated plant that has escaped from agriculture, forestry or garden cultivation and has become naturalized in the wild. Usually not native to an area, escaped plants may become Invasive species, invasive. Therefore, escaped plants are the subject of research in invasion biology.Mulvaney M (2001) The effect of introduction pressure on the naturalisation of ornamental woody plants in south-eastern Australia. In 'Weed Risk Assessment'. (Eds RH Groves, FD Panetta, JG Virtue). (CSIRO Publishing: Collingwood) Some ornamental plants have characteristics which allow them to escape cultivation and become weedy in alien ecosystems with far-reaching ecological and economic consequences. Escaped garden plants may be called garden escapes or escaped ornamentals. Sometimes, their origins can even be traced back to botanical gardens. All escaped plants belong to the so-called Hemerochory, hemerochoric plants. This term is used across the board for plants that ...

Naturalization
Naturalization (or naturalisation) is the legal act or process by which a non-national of a country acquires the nationality of that country after birth. The definition of naturalization by the International Organization for Migration of the United Nations excludes citizenship that is automatically acquired (e.g. at birth) or is acquired by declaration. Naturalization usually involves an application or a motion and approval by legal authorities. The rules of naturalization vary from country to country but typically include a promise to obey and uphold that country's laws and taking and subscribing to an oath of allegiance, and may specify other requirements such as a minimum legal residency and adequate knowledge of the national dominant language or culture. To counter multiple citizenship, some countries require that applicants for naturalization renounce any other citizenship that they currently hold, but whether this renunciation actually causes loss of original citizen ...

Mespilus
''Mespilus'', commonly called medlar, is a genus of flowering plants in the family Rosaceae containing the single species '' Mespilus germanica'' of southwest Asia. It is also found in some countries in the Balkans, especially in Albanian, Macedonian and Bulgarian regions, and in western parts of Caucasian Georgia. A second proposed species, '' Mespilus canescens'', discovered in North America in 1990, proved to be a hybrid between ''M. germanica'' and one or more species of hawthorn, and is properly known as ''× Crataemespilus canescens''. Plant ''Mespilus'' forms deciduous large shrubs to small trees growing up to tall. The fruit is a matte brown pome. History ''Mespilus germanica'' is apparently native only to southwest Asia and southeastern Europe, i.e. near the Black Sea coast and western Mediterranean, and Asia Minor, as well as the Caucasus and northern Iran, but it has an ancient history of cultivation and wild plants exist in a much wider area; it was grown by ...

Jean-Baptiste Lamarck
Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck (; ), was a French naturalist, biologist, academic, and soldier. He was an early proponent of the idea that biological evolution occurred and proceeded in accordance with Naturalism (philosophy), natural laws. Lamarck fought in the Seven Years' War against Prussia, and was awarded a commission for bravery on the battlefield. Posted to Monaco, Lamarck became interested in natural history and resolved to study medicine.#Packard, Packard (1901), p. 15. He retired from the army after being injured in 1766, and returned to his medical studies. Lamarck developed a particular interest in botany, and later, after he published the three-volume work ''Flore françoise'' (1778), he gained membership of the French Academy of Sciences in 1779. Lamarck became involved in the Jardin des Plantes and was appointed to the Chair of Botany in 1788. When the French Nationa ...
