Spiranthes Odorata
''Spiranthes odorata'', marsh lady's tresses or common lady's tresses, is a species of flowering plant in the orchid family, native to the southeastern United States, from Texas eastwards and northwards to Delaware. It grows in moist, partially shaded environments with acidic or neutral soil. An herbaceous perennial, this orchid grows up to tall and broad. The flowers are borne in dense vertical rows on sturdy green spikes, in a slightly twisted pattern (hence ''Spiranthes'', "twisted flower"). This effect is due to uneven cell growth. The flowers, which appear in late summer and autumn, are white, hooded and fragrant (hence the specific epithet ''odorata''). This plant is pollinated by bumblebees, notably '' Bombus pensylvanicus'', '' Bombus fervidus'', '' Bombus impatiens'', and ''Bombus nevadensis''. In the UK, the cultivar ‘Chadd’s Ford’ has gained the Royal Horticultural Society’s Award of Garden Merit. Requiring a fertile soil in partial shade, it is hardy dow ...

Bombus Fervidus
''Bombus fervidus'', the golden northern bumble bee or yellow bumblebee, is a species of bumblebee native to North America. It has a yellow-colored abdomen and thorax. Its range includes the North American continent, excluding much of the southern United States, Alaska, and the northern parts of Canada. It is common in cities and farmland, with populations concentrated in the Northeastern part of the United States. It is similar in color and range to its sibling species, '' Bombus californicus'', though sometimes also confused with the American bumblebee (''Bombus pensylvanicus'') or black and gold bumblebee (''Bombus auricomus''). It has complex behavioral traits, which includes a coordinated nest defense to ward off predators. ''B. fervidus'' is an important pollinator, so recent population decline is a particular concern. Taxonomy and phylogeny Danish zoologist Johan Christian Fabricius first identified ''Bombus fervidus,'' also known as the yellow bumblebee or golden northern ...

Hardiness (plants)
Hardiness of plants describes their ability to survive adverse growing conditions. It is usually limited to discussions of climatic adversity. Thus a plant's ability to tolerate cold, heat, drought, flooding, or wind are typically considered measurements of hardiness. Hardiness of plants is defined by their native extent's geographic location: longitude, latitude and elevation. These attributes are often simplified to a hardiness zone. In temperate latitudes, the term most often describes resistance to cold, or "cold-hardiness", and is generally measured by the lowest temperature a plant can withstand. Hardiness of a plant is usually divided into two categories: tender, and hardy. (Some sources also use the erroneous terms "Half-hardy" or "Fully hardy".) Tender plants are those killed by freezing temperatures, while hardy plants survive freezing—at least down to certain temperatures, depending on the plant. "Half-hardy" is a term used sometimes in horticulture to describe bed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Bombus Nevadensis
''Bombus nevadensis'', the Nevada bumblebee, is a species of bumblebee. It is native to North America, where it occurs from Alaska to California in the west, and east to Wisconsin, and in Arizona, New Mexico, and Mexico. Description A bumblebee with a long proboscis (tongue) and a short, dense fur, the females (queens and workers) have an entirely black head, while the face and top of the head of the male are yellow. The thorax is yellow, sometimes with a hairless, black spot in the middle. The three first terga (abdominal segments) are yellow, while the rest of the abdomen is black. However, the tip of the tail is more or less red in the male. The average body length is for the queen, (worker) and (male). The black and gold bumblebee (''Bombus auricomus'') is sometimes considered a subspecies of this species, ''B. nevadensis auricomus''. Genetic and morphological evidence supports them as separate species.Hatfield, R., et al. 2015''Bombus nevadensis''.The IUCN Red List of T ...

Bombus Impatiens
''Bombus impatiens'', the common eastern bumble bee, is the most commonly encountered bumblebee across much of eastern North America. They can be found in the Eastern temperate forest region of the eastern United States, southern Canada, and the eastern Great Plains. Because of their great adaptability, they can live in country, suburbs, and even urban cities. This adaptability makes them a great pollinator species, leading to an increase in their commercial use by greenhouse industry. This increase consequently led to their farther spread outside their previous distribution range. They are considered one of the most important species of pollinator bees in North America. Taxonomy and phylogeny The generic epithet (the first part of the name) ''Bombus'' comes from the genus ''Bombus'', which is also commonly known as bumblebee and belongs to the tribe ''Bombini''. The specific name (the latter half of its scientific name) may come from the flowers of the genus '' Impatiens, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombus Pensylvanicus
''Bombus pensylvanicus'', the American bumblebee, is a threatened species of bumblebee native to North America. It occurs in eastern Canada, throughout much of the Eastern United States, and much of Mexico.Hatfield, R., et al. 2015''Bombus pensylvanicus''.The IUCN Red List of Threatened Species. Downloaded on 09 March 2016. Once the most prevalent bumblebee in the southern United States, populations of ''Bombus pensylvanicus'' have decreased significantly in recent years, including in its scientific namesake state of Pennsylvania where its numbers are considered critically low. Overall, the population has dropped nearly 90% in just the last 20 years. ''Bombus pensylvanicus'' tends to live and nest in open farmland and fields. It feeds on several food plants, favoring sunflowers and clovers, and functions as a pollinator. Taxonomy and phylogenetics ''Bombus pensylvanicus'' belongs to the order Hymenoptera (consisting of ants, wasps, bees, and sawflies), the family Apidae (consist ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bumblebee
A bumblebee (or bumble bee, bumble-bee, or humble-bee) is any of over 250 species in the genus ''Bombus'', part of Apidae, one of the bee families. This genus is the only extant group in the tribe Bombini, though a few extinct related genera (e.g., ''Calyptapis'') are known from fossils. They are found primarily in higher altitudes or latitudes in the Northern Hemisphere, although they are also found in South America, where a few lowland tropical species have been identified. European bumblebees have also been introduced to New Zealand and Tasmania. Female bumblebees can sting repeatedly, but generally ignore humans and other animals. Most bumblebees are social insects that form colonies with a single queen. The colonies are smaller than those of honey bees, growing to as few as 50 individuals in a nest. Cuckoo bumblebees are brood parasitic and do not make nests or form colonies; their queens aggressively invade the nests of other bumblebee species, kill the resident queen ...
