Choisya 'Aztec Pearl' Detail
''Choisya'' is a small genus of aromatic evergreen shrubs in the rue family, Rutaceae. Members of the genus are commonly known as Mexican orange due to the similarity of their flowers with those of the closely related Orange (fruit), orange, both in shape and scent. They are native plant, native to southern North America, from Arizona, New Mexico, Texas and south through most of Mexico. In its generic name Friedrich Wilhelm Heinrich Alexander von Humboldt, Humboldt and Aimé Jacques Alexandre Bonpland, Bonpland honoured Swiss botanist Jacques Denys Choisy, Jacques Denis Choisy (1799–1859).

Carl Sigismund Kunth
Carl Sigismund Kunth (18 June 1788 – 22 March 1850), also Karl Sigismund Kunth or anglicized as Charles Sigismund Kunth, was a German botanist. He is known for being one of the first to study and categorise plants from the Americas, American continents, publishing ''Nova genera et species plantarum quas in peregrinatione ad plagam aequinoctialem orbis novi collegerunt Bonpland et Humboldt'' (7 vols., Paris, 1815–1825). Born in Leipzig, Kunth became a merchant's clerk in Berlin in 1806. After meeting Alexander von Humboldt, who helped him attend lectures at the University of Berlin, Kunth became interested in botany. Kunth worked as Humboldt's assistant in Paris from 1813 to 1819. He classified plants that had been collected by Humboldt and Aimé Bonpland during their journey through the Americas. When Kunth returned to Berlin in 1820, he became Professor of Botany at the University of Berlin, as well as the Vice President of the Berlin botanical garden. In 1829, he was ele ...

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...

Quinoline Alkaloids
Quinoline alkaloids are naturally occurring chemical compounds from the group of alkaloids, which are chemically derived from quinoline. Some quinoline alkaloids show antiseptic, convulsive or antineoplastic effects. Examples Alkaloids with a quinoline partial structure are widespread and are usually further subdivided according to their occurrence and biogenetic origin. Among the quinoline alkaloids are the cinchona alkaloids quinine and quinidine, which are important due to their therapeutic potential, furthermore cinchonine and cinchonidine, as well as some furoquinoline alkaloids and acridine alkaloids. Strychnine and brucine, alkaloids of the nux vomica, which have a hydrogenated quinoline system, are also counted among the quinoline alkaloids. Also nitramarine (1-(2-quinolinyl)-β-carboline) belongs to the quinoline alkaloids.

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 ...

Nectar
Nectar is a sugar-rich liquid produced by plants in glands called nectaries or nectarines, either within the flowers with which it attracts pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal mutualists, which in turn provide herbivore protection. Common nectar-consuming pollinators include mosquitoes, hoverflies, wasps, bees, butterflies and moths, hummingbirds, honeyeaters and bats. Nectar plays a crucial role in the foraging economics and evolution of nectar-eating species; for example, nectar foraging behavior is largely responsible for the divergent evolution of the African honey bee, ''A. m. scutellata'' and the western honey bee. Nectar is an economically important substance as it is the sugar source for honey. It is also useful in agriculture and horticulture because the adult stages of some predatory insects feed on nectar. For example, a number of parasitoid wasps (e.g. the social wasp species ''Apoica flavissima'') rely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forage (honey Bee)
For bees, their forage or food supply consists of nectar and pollen from blooming plants within flight range. The forage sources for honey bees are an important consideration for beekeepers. In order to determine where to locate hives for maximum honey production and brood one must consider the off-season. If there are no honey flows the bees may have to be fed. Bees that are used for commercial pollination are usually fed in the holding yards. Forage is also significant for pollination management with other bee species. Nectar contains sugars that are the primary source of energy for the bees' wing muscles and for heat for honey bee colonies for winter. Pollen provides the protein and trace minerals that are mostly fed to the brood in order to replace bees lost in the normal course of life cycle and colony activity. As a rule of thumb the foraging area around a beehive extends for , although bees have been observed foraging twice and three times this distance from the hive. E ...

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] |

Capsule (fruit)
In botany a capsule is a type of simple, dry, though rarely fleshy dehiscent fruit produced by many species of angiosperms (flowering plants). Origins and structure The capsule (Latin: ''capsula'', small box) is derived from a compound (multicarpeled) ovary. A capsule is a structure composed of two or more carpels. In (flowering plants), the term locule (or cell) is used to refer to a chamber within the fruit. Depending on the number of locules in the ovary, fruit can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the ovules or seeds and are separated by septa. Dehiscence In most cases the capsule is dehiscent, i.e. at maturity, it splits apart (dehisces) to release the seeds within. A few capsules are indehiscent, for example those of ''Adansonia digitata'', ''Alphitonia'', and '' Merciera''. Capsules are often classif ...
