Cenchrus
''Cenchrus'' is a widespread genus of plants in the grass family, native to tropical and warm temperate regions of the world. Its species are native to many countries in Asia, Africa, Australia, the Americas, and various oceanic islands. Common names include buffelgrasses, sandburs, and sand spur. Such names allude to the sharp, spine-covered burrs characterizing the inflorescences of the members of the genus. Those previously classified as ''Pennisetum'' are known commonly as fountaingrasses (fountain grasses).''Pennisetum''. Integrated Taxonomic Information System (ITIS).''Pennisetum''.

Cenchrus Longispinus
''Cenchrus longispinus'' is a species of grass, also known as spiny burr grass or gentle Annie or picco. Its fruits are clumped into " burrs" with sharp, barbed spines that can penetrate the hides and mouth of grazing animals. They can also become lodged in human clothing and skin, causing some discomfort. This activity is important for the plant's seed dispersal, as the plant is a summer annual. The species has a prostrate habit when there is no competition for light. The species is native to North America and is considered as a noxious weed A noxious weed, harmful weed or injurious weed is a weed that has been designated by an agricultural or other governing authority as a plant that is harmful to agricultural or horticultural crops, natural habitats or ecosystems, or humans or lives ... in Europe, Australia and New Zealand where it was introduced.Sousa Sánchez, M. & E.

Pennisetum Purpureum
''Cenchrus purpureus'', Synonym (taxonomy), synonym ''Pennisetum purpureum'', also known as Napier grass, elephant grass or Uganda grass, is a species of perennial tropical grass native to African grasslands.[Farrell, G., Simons, S. A., & Hillocks, R. J. (2002). Pests, diseases, and weeds of Napier grass, ''Pennisetum purpureum'': a review. International Journal of Pest Management, 48(1), 39-48.] It has low water and nutrient requirements, and therefore can make use of otherwise uncultivated lands.[Strezov, V., Evans, T. J., & Hayman, C. (2008). Thermal conversion of elephant grass ''Pennisetum purpureum'' Schum) to biogas, bio-oil and charcoal. Bioresources Technology, 99, 8394-8399.] Historically, this wild species has been used primarily for grazing, recently, however, it has been used as part of a push–pull agricultural pest management strategy. Napier grasses improve soil fertility, and protect arid land from soil erosion. It is also utilized for firebreaks, windbreaks, i ...

Pearl Millet
Pearl millet (''Cenchrus americanus'', commonly known as the synonym ''Pennisetum glaucum'') is the most widely grown type of millet. It has been grown in Africa and the Indian subcontinent since prehistoric times. The center of diversity, and suggested area of domestication, for the crop is in the Sahel zone of West Africa. Recent archaeobotanical research has confirmed the presence of domesticated pearl millet on the Sahel zone of northern Mali between 2500 and 2000 BC. 2023 was the , declared by the United Nations General Assembly in 2021. Description Pearl millet has ovoid grains of length, the largest kernels of all varieties of millet (not including sorghum). These can be nearly white, pale yellow, brown, grey, slate blue or purple. The 1000-seed weight can be anything from 2.5 to 14 g with a mean of 8 g. The height of the plant ranges from . Cultivation Pearl millet is well adapted to growing areas characterized by drought, low soil fertility, low moisture, and high t ...

Pennisetum Villosum
''Cenchrus longisetus'', previously ''Pennisetum villosum'', is a species of flowering plant in the family (botany), family Poaceae, known by the common name feathertop grass or just feathertop. It is native to northeastern Africa and parts of the Arabian Peninsula, and it is grown elsewhere as an ornamental plant. It can sometimes be found growing wild where it has escaped plant, escaped cultivation. This is a perennial grass growing in rhizome, rhizomatous clumps, producing erect stems up to about 75 centimeters tall. The inflorescence is a panicle of clustered spikelets surrounded by a cloudlike mass of plumose white bristles up to 5 centimeters long. The Latin binomial nomenclature, specific epithet ''villosum'' means "with soft hairs". In temperate climates it is hardy in mild or coastal areas, where temperatures do not fall much below freezing. Alternatively it is often grown as an annual plant, annual. This plant has gained the Royal Horticultural Society's Award of Garde ...

Herbivore
A herbivore is an animal anatomically and physiologically evolved to feed on plants, especially upon vascular tissues such as foliage, fruits or seeds, as the main component of its diet. These more broadly also encompass animals that eat non-vascular autotrophs such as mosses, algae and lichens, but do not include those feeding on decomposed plant matters (i.e. detritivores) or macrofungi (i.e. fungivores). As a result of their plant-based diet, herbivorous animals typically have mouth structures ( jaws or mouthparts) well adapted to mechanically break down plant materials, and their digestive systems have special enzymes (e.g. amylase and cellulase) to digest polysaccharides. Grazing herbivores such as horses and cattles have wide flat- crowned teeth that are better adapted for grinding grass, tree bark and other tougher lignin-containing materials, and many of them evolved rumination or cecotropic behaviors to better extract nutrients from plants.

Noxious Weed
A noxious weed, harmful weed or injurious weed is a weed that has been designated by an agricultural or other governing authority as a plant that is harmful to agricultural or horticultural crops, natural habitats or ecosystems, or humans or livestock. Most noxious weeds have been introduced species, introduced into an ecosystem by ignorance, mismanagement, or accident. Some noxious weeds are native, though many localities define them as necessarily being non-native. Typically they are plants that grow aggressively, multiply quickly without natural controls (native herbivores, soil chemistry, etc.), and display adverse effects through contact or ingestion. Noxious weeds are a large problem in many parts of the world, greatly affecting areas of agriculture, forestry, forest management, nature reserves, regional park, parks and other open space. Many noxious weeds have come to new regions and countries through contaminated shipments of feed and crop seeds or were intentionally introd ...

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. History The Award of Garden Merit is a mark of quality aw ... [...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 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 ...
