Darjeeling
Darjeeling (, , ) is a town and municipality in the northernmost region of the Indian state of West Bengal. Located in the Eastern Himalayas, it has an average elevation of . To the west of Darjeeling lies the easternmost province of Nepal, to the east the Kingdom of Bhutan, to the north the Indian state of Sikkim, and farther north the Tibet Autonomous Region region of China. Bangladesh lies to the south and southeast, and most of the state of West Bengal lies to the south and southwest, connected to the Darjeeling region by a narrow tract. Kangchenjunga, the world's third-highest mountain, rises to the north and is prominently visible on clear days. In the early 19th century, during East India Company rule in India, Darjeeling was identified as a potential summer retreat for British officials, soldiers and their families. The narrow mountain ridge was leased from the Kingdom of Sikkim, and eventually annexed to British India. Experimentation with growing tea on the slop ...

Hardiness Zone
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries (such as Canada) in various forms. Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale. For example, a plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 °F (−1.1 °C) to 40 °F (4.4 °C). Other hardiness rating schemes have been developed as well, such as the UK Royal Horticultural Society and US Sunset Western Garden Book systems. A heat zone (s ...

Perlite
Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. It is an industrial mineral, suitable "as ceramic flux to lower the sintering temperature", and a commercial product useful for its low density after processing. Properties Perlite softens when it reaches temperatures of . Water trapped in the structure of the material vaporises and escapes, and this causes the expansion of the material to 7–16 times its original volume. The expanded material is a brilliant white, due to the reflectivity of the trapped bubbles. Unexpanded ("raw") perlite has a bulk density around 1100 kg/m3 (1.1 g/cm3), while typical expanded perlite has a bulk density of about 30–150 kg/m3 (0.03–0.150 g/cm3).

Hampshire
Hampshire (, ; abbreviated to Hants) is a ceremonial county, ceremonial and non-metropolitan county, non-metropolitan counties of England, county in western South East England on the coast of the English Channel.

Stockbridge, Hampshire
Stockbridge is a small town and civil parish in the Test Valley district of Hampshire, England. It is one of the smallest towns in the United Kingdom with a population of 592 at the 2011 census. It sits astride the River Test and at the foot of Stockbridge Down. Description The town is situated on the A30 road, which once carried most of the traffic from London to Dorset, south Somerset, Devon and Cornwall in the South West, though today this route is less important than the A303 dual carriageway to the north. The bridge over the Test led to the town's name, a local legend suggested a coach stop stocked provisions, but it derives from an earlier bridge that was made of 'stocks' (tree trunks). Salisbury is by road; Winchester is by the B3049 road that joins the A30 nearby. The town's long high street was thus on a useful route between the two medieval cathedral cities. The town's civil parish has an area of . The town's street crosses the River Test, marking the border of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Longstock Park
Longstock Park is in the civil parish of Longstock in the Test Valley district of Hampshire, England, and forms part of the Leckford Estate (1520 ha.), wholly owned by the John Lewis Partnership. Description Formerly Longstock Manor, of medieval origins, the park was purchased by Sir Joshua East in 1849. On his death, the park passed to his sons Alfred and Arthur. In 1914, the park became the home of the Beddington family until 1945, when it was sold to John Spedan Lewis, founder of the John Lewis Partnership. Lewis lived at Longstock House throughout his retirement until his death in 1963, after which the house became a retreat for the company's executives.

Windsor Castle
Windsor Castle is a royal residence at Windsor in the English county of Berkshire. It is strongly associated with the English and succeeding British royal family, and embodies almost a millennium of architectural history. The original castle was built in the 11th century, after the Norman invasion of England by William the Conqueror. Since the time of Henry I (who reigned 1100–1135), it has been used by the reigning monarch and is the longest-occupied palace in Europe. The castle's lavish early 19th-century state apartments were described by early 20th century art historian Hugh Roberts as "a superb and unrivalled sequence of rooms widely regarded as the finest and most complete expression of later Georgian taste".Hugh Roberts, ''Options Report for Windsor Castle'', cited Nicolson, p. 79. Inside the castle walls is the 15th-century St George's Chapel, considered by the historian John Martin Robinson to be "one of the supreme achievements of English Perpe ...

Trichome
Trichomes (); ) are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be pubescent. Algal trichomes Certain, usually filamentous, algae have the terminal cell produced into an elongate hair-like structure called a trichome. The same term is applied to such structures in some cyanobacteria, such as '' Spirulina'' and ''Oscillatoria''. The trichomes of cyanobacteria may be unsheathed, as in ''Oscillatoria'', or sheathed, as in ''Calothrix''. These structures play an important role in preventing soil erosion, particularly in cold desert climates. The filamentous sheaths form a persistent sticky network that helps maintain soil structure. Plant trichomes Plant trichomes have many different features that vary between both species of plants an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
