Hen And Chicks
Hen and chicks (also known as hen-and-chickens, or hen-widdies in the southern United States) is a common name for a group of small succulent plants, a term that indicates a plant that possesses enlarged parts to store water. It belongs to the flowering plant family Crassulaceae, native to southern Europe and northern Africa. The plants grow close to the ground with leaves formed around each other in a Rosette (botany), rosette, and propagating by offset (botany), offsets. The "hen" is the main, or mother, plant, and the "chicks" are a flock of offspring, which start as tiny buds on the main plant and soon sprout their own roots, taking up residence close to the mother plant. Plants commonly referred to as "Hens and chicks" include ground-hugging species of ''Sempervivum'' (houseleeks) such as ''Sempervivum'' 'Pekinese', ''Sempervivum arachnoideum, S. arachnoideum'' (cobweb houseleek), and ''Sempervivum tectorum, S. tectorum'' (common houseleek), as well as members of the rela ...

Loch 4
''Loch'' () is the Scottish Gaelic, Scots language, Scots and Irish language, Irish word for a lake or sea inlet. It is Cognate, cognate with the Manx language, Manx lough, Cornish language, Cornish logh, and one of the Welsh language, Welsh words for lake, llwch. In English English and Hiberno-English, the Anglicisation, anglicised spelling lough is commonly found in place names; in Lowland Scots and Scottish English, the spelling "loch" is always used. Many loughs are connected to stories of lake-bursts, signifying their mythical origin. Sea-inlet lochs are often called sea lochs or sea loughs. Some such bodies of water could also be called firths, fjords, estuary, estuaries, straits or bays.

Sedum
''Sedum'' is a large genus of flowering plants in the family Crassulaceae, members of which are commonly known as stonecrops. The genus has been described as containing up to 600 species, subsequently reduced to 400–500. They are leaf succulents found primarily in the Northern Hemisphere, but extending into the southern hemisphere in Africa and South America. The plants vary from annual and creeping herbs to shrubs. The plants have water-storing leaves. The flowers usually have five petals, seldom four or six. There are typically twice as many stamens as petals. Various species formerly classified as ''Sedum'' are now in the segregate genera '' Hylotelephium'' and ''Rhodiola''. Well-known European species of ''Sedum'' are ''Sedum acre'', ''Sedum album'', '' Sedum dasyphyllum'', '' Sedum reflexum'' (also known as ''Sedum rupestre'') and ''Sedum hispanicum''. Description ''Sedum'' is a genus that includes annual, biennial, and perennial herbs. They are characterised by succulen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drought-tolerant Plants
Drought tolerance is the ability to which a plant maintains its biomass production during arid or drought conditions. Some plants are naturally adapted to dry conditions'','' surviving with protection mechanisms such as desiccation tolerance, detoxification, or repair of xylem embolism. Other plants, specifically crops like corn, wheat, and rice, have become increasingly tolerant to drought with new varieties created via genetic engineering. The plants behind drought tolerance are complex and involve many pathways which allows plants to respond to specific sets of conditions at any given time. Some of these interactions include stomatal conductance, carotenoid degradation and anthocyanin accumulation, the intervention of osmoprotectants (such as sucrose, glycine, and proline Proline (symbol Pro or P) is an organic acid classed as a proteinogenic amino acid (used in the biosynthesis of proteins), although it does not contain the amino group but is rather a secondary amine.

Garden Plants Of Europe
A garden is a planned space, usually outdoors, set aside for the cultivation, display, and enjoyment of plants and other forms of nature. The single feature identifying even the wildest wild garden is ''control''. The garden can incorporate both natural and artificial materials. Gardens often have design features including statuary, follies, pergolas, trellises, stumperies, dry creek beds, and water features such as fountains, ponds (with or without fish), waterfalls or creeks. Some gardens are for ornamental purposes only, while others also produce food crops, sometimes in separate areas, or sometimes intermixed with the ornamental plants. Food-producing gardens are distinguished from farms by their smaller scale, more labor-intensive methods, and their purpose (enjoyment of a hobby or self-sustenance rather than producing for sale, as in a market garden). Flower gardens combine plants of different heights, colors, textures, and fragrances to create interest and delight the se ...

Flora Of North Africa
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea ...

Succulent Plants
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word ''succulent'' comes from the Latin word ''sucus'', meaning "juice" or "sap". Succulent plants may store water in various structures, such as leaves and stems. The water content of some succulent organs can get up to 90–95%, such as '' Glottiphyllum semicyllindricum'' and '' Mesembryanthemum barkleyii''. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. The habitats of these water-preserving plants are often in areas with high temperatures and low rainfall, such as deserts, but succulents may be found even in alpine ecosystems growing in rocky soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist and dew, which makes them equipped to su ...

Hen And Chicken Plant
{{Plant com ...
Hen and chicken is a common name for several unrelated groups of plants. The name refers to the tendency of certain of these species to reproduce vegetatively by means of plantlets. These tiny plants are produced by the mother plant, and take root on touching the ground. The name may refer to: *'' Chlorophytum comosum'', the commonly cultivated houseplant *''Sempervivum'' & ''Jovibarba'', two related genera of small succulent plant species, commonly called "Hen and chicks" *''Echeveria'', a genus of succulent plant species *''Sedum'', a genus of succulent plant species *''Bergenia'', a non-succulent Asian plant genus *'' Asplenium bulbiferum'', the "hen and chicken fern" of New Zealand See also Hen and chicks Hen and chicks (also known as hen-and-chickens, or hen-widdies in the southern United States) is a common name for a group of small succulent plants, a term that indicates a plant that possesses enlarged parts to store water.

Antioxidant
Antioxidants are compounds that inhibit oxidation, a chemical reaction that can produce free radicals. This can lead to polymerization and other chain reactions. They are frequently added to industrial products, such as fuels and lubricants, to prevent oxidation, and to foods to prevent spoilage, in particular the rancidification of oils and fats. In cells, antioxidants such as glutathione, mycothiol or bacillithiol, and enzyme systems like superoxide dismutase, can prevent damage from oxidative stress. The only dietary antioxidants are vitamins A, C, and E, but the term ''antioxidant'' has also been applied to numerous other dietary compounds that only have antioxidant properties in vitro, with little evidence for antioxidant properties in vivo. Dietary supplements marketed as antioxidants have not been shown to maintain health or prevent disease in humans. History As part of their adaptation from marine life, terrestrial plants began producing non-marine antioxi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antimicrobial
An antimicrobial is an agent that kills microorganisms or stops their growth. Antimicrobial medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria, and antifungals are used against fungi. They can also be classified according to their function. Agents that kill microbes are microbicides, while those that merely inhibit their growth are called bacteriostatic agents. The use of antimicrobial medicines to treat infection is known as antimicrobial chemotherapy, while the use of antimicrobial medicines to prevent infection is known as antimicrobial prophylaxis. The main classes of antimicrobial agents are disinfectants (non-selective agents, such as bleach), which kill a wide range of microbes on non-living surfaces to prevent the spread of illness, antiseptics (which are applied to living tissue and help reduce infection during surgery), and antibiotics (which destroy microorganisms within the body).

Aloe Vera
''Aloe vera'' () is a succulent plant species of the genus ''Aloe''. It is widely distributed, and is considered an invasive species in many world regions. An evergreen perennial, it originates from the Arabian Peninsula, but grows wild in tropical, semi-tropical, and arid climates around the world. It is cultivated for commercial products, mainly as a topical treatment used over centuries. The species is attractive for decorative purposes, and succeeds indoors as a potted plant. It is used in many consumer products, including beverages, skin lotion, cosmetics, ointments or in the form of gel for minor burns and sunburns. There is little clinical evidence for the effectiveness or safety of ''Aloe vera'' extract as a cosmetic or topical drug, and oral ingestion has risk of toxicity. Etymology The genus name ''Aloe'' is derived from the Arabic word ''alloeh'', meaning "bitter and shiny substance" or from Hebrew ''ahalim'', plural of ''ahal''. The specific epithet ''vera'' ...

Root Rot
Root rot is a condition in which anoxic conditions in the soil or potting media around the roots of a plant cause them to rot. This occurs due to excessive standing water around the roots. It is found in both indoor and outdoor plants, although it is more common in indoor plants due to overwatering, heavy potting media, or containers with poor drainage. The leaves of plants experiencing root rot often yellow and die, and if allowed to continue, the condition can be fatal. To avoid root rot, it is best to only water plants when the soil becomes dry, and to put the plant in a well-drained pot. Using a dense potting media such as one dug up from outdoors can also cause root rot. Plants from different environments have different tolerances for soil moisture: plants evolved for desert conditions will experience root rot at lower moisture levels than plants evolved for tropical conditions. In both indoor and outdoor plants, it can be lethal and there is no effective treatment, though ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
