Cleome Hassleriana
''Cleome houtteana'', commonly known as spider flower, spider plant, pink queen, or grandfather's whiskers, is a species of flowering plant in the genus '' Cleome'' of the family Cleomaceae, native to southern South America in Argentina, Paraguay, Uruguay, and southeast Brazil. It has also been introduced to South Asia, including the Haor area of Bangladesh and India. It is an annual growing to a height of , with spirally arranged leaves. It has a height of 90 cm (35 in) to 180 cm (71 in). The leaves are palmately compound, with five or seven leaflets, the leaflets up to long and broad and the leaf petiole up to long. Its maximum crown width ranges from 30 cm (12 in) to 60 cm (24 in). The plant is sometimes mistakenly identified as cannabis due to its leaves and general growth shape. The flowers are purple, pink, or white, with four petals and six long stamens. The fruit is a capsule up to 15 cm long and broad, containing several ...

Diederich Franz Leonhard Von Schlechtendal
Diederich Franz Leonhard von Schlechtendal (27 November 1794, Xanten – 12 October 1866, Halle an der Saale, Halle) was a German botanist. Life and work Von Schlechtendal was born in Xanten, Xanten am Rhein and when his father Diederich Friedrich Carl von Schlechtendal (1767-1842) became a court judge. His mother Katharina Margarete Schlechtendal, née Bartels died when he was just three. His father lost his job when the French occupied the left bank of the Rhine and the family moved to Berlin. Contact with Carl Ludwig Willdenow, Carl Willdenow made him interested in botany at an early age. He went to the gymnasium in Berlin and then in a monastery school before joining voluntary military service in Breslau. He was dismissed for being physically unfit and he returned to Berlin to study botany. In 1813 he attended lectures in botany and medicine under Christoph Wilhelm Hufeland (1762-1836), Carl August Wilhelm Berends, Karl August Berends (1795-1826), and Karl Ferdinand von Gr ...

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 (multicarpellary) 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 ...

Flora Of Uruguay
The flora of Uruguay consists of 2,500 species distributed among 150 native and foreign biological families. Approximately 80% of Uruguay is prairie, with grasses predominating. Uruguay is primarily a grass-growing land, with vegetation that is essentially a continuation of the Argentine Pampas. Forest areas are relatively small. Trees grow in bunches. Forested areas are much smaller than in the pampas, but contain a mix of hardwoods and softwoods, while eucalyptus were imported from Australia. "Ceibo", or '' Erythrina cristagalli'', is the national flower. Herbs Uruguay contains many herbs, ferns, and flowers. Riverine forests Natural forests in Uruguay mainly grow near rivers in the countryside. The native forests are composed of more than 500 native species, including palms. The most abundant are "sauce criollo" ('' Salix humboldtiana''), "sarandí colorado" (''Cephalanthus glabratus''), "sarandí blanco" ('' Phyllanthus sellowianus'') and "mataojos" ('' Pouteria salicif ...

Flora Of Argentina
The environment of Argentina is highly biodiverse. Biodiversity Flora Subtropical plants dominate the Gran Chaco in the north, with the '' Dalbergia'' genus of trees well represented by Brazilian rosewood and the quebracho tree; also predominant are the wacho white and black algarrobo trees ('' Prosopis alba'' and ''Prosopis nigra''). Savannah-like areas exist in the drier regions nearer the Andes. Aquatic plants thrive in the wetlands of Argentina. In central Argentina the ''humid pampas'' are a true tallgrass prairie ecosystem. In Argentina forest cover is around 10% of the total land area, equivalent to 28,573,000 hectares (ha) of forest in 2020, down from 35,204,000 ha in 1990. In 2020, naturally regenerating forest covered 27,137,000 ha and planted forest covered 1,436,000 ha. Of the naturally regenerating forest 0% was reported to be primary forest (consisting of native tree species with no clearly visible indications of human activity) and around 7% o ...

Annual Plants
An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies. Globally, 6% of all plant species and 15% of herbaceous plants (excluding trees and shrubs) are annuals. The annual life cycle has independently emerged in over 120 different plant families throughout the entire angiosperm phylogeny. The evolutionary and ecological drivers of the annual life cycle Traditionally, there has been a prevailing assumption that annuals have evolved from perennial ancestors. However, recent research challenges this notion, revealing instances where perennials have evolved from annual ancestors. Intriguingly, models propose that transition rates from an annual to a perennial life cycle are twice as fast as the reverse transition. The life-history theory posits that annual plants are favored when adult mortality is higher than seedling (or seed) mortality, i.e., annuals will dominate environments with distu ...

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 ...

Cultivar
A cultivar is a kind of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and which retains those traits when Plant propagation, propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human genetic engineering, 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, 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 may be divided into two categories: tender, and 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 bedding plants which are sown in heat in winter or early spring, and planted outsi ...

Temperateness
In geography, the temperate climates of Earth occur in the middle latitudes (approximately 23.5° to 66.5° N/S of the Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small; they usually differ only in the amount of precipitation. In temperate climates, not only do latitudinal positions influence temperature changes, but various sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistence of frost. However, some adaptations of Köppen set the minimum at . Continental climates are classified as D and considered to be varieties of temperate climates, ...
