Chichester
–
Chichester is a cathedral city in West Sussex, in South-East England. It is the city in West Sussex and is its county town. It has a history as a settlement from Roman times and was important in Anglo-Saxon times. It is the seat of a bishopric, with a 12th-century cathedral, Chichester has three tiers of local government. It is a hub, and a centre for culture in the county, with a theatre, museum. Chichester Harbour and the South Downs provide opportunities for outdoor pursuits, the city centre stands on the foundations of the Romano-British city of Noviomagus Reginorum, capital of the Civitas Reginorum. The Roman road of Stane Street, connecting the city with London, started at the east gate, the plan of the city is inherited from the Romans, the North, South, East and West shopping streets radiate from the central market cross dating from medieval times. The original Roman city wall was over 6½ feet thick with a steep ditch and it survived for over one and a half thousand years but was then replaced by a thinner Georgian wall. The city was home to some Roman baths, found down Tower Street when preparation for a new car park was under way. A museum, the Novium, preserving the baths was opened on 8 July 2012, an amphitheatre was built outside the city walls, close to the East Gate, in around 80 AD. The area is now a park, but the site of the amphitheatre is discernible as a bank approximately oval in shape. In January 2017, archaeologists using underground radar reported the discovery of the relatively untouched ground floor of a Roman townhouse, the exceptional preservation is due to the fact the site, Priory Park, belonged to a monastery and has never been built upon since Roman times. According to the Anglo-Saxon Chronicle it was captured towards the close of the century, by Ælle. It was the city of the Kingdom of Sussex. The cathedral for the South Saxons was founded in 681 at Selsey, Chichester was one of the burhs established by Alfred the Great, probably in 878-9, making use of the remaining Roman walls. The system was supported by a network based on hilltop beacons to provide early warning. It has been suggested that one such link ran from Chichester to London, when the Domesday Book was compiled, Chichester consisted of 300 dwellings which held a population of 1,500 people. There was a mill named Kings Mill that would have been rented to local slaves and villeins

Rolls-Royce Motor Cars
–
Rolls-Royce Motor Cars Limited engineers, manufactures and distributes luxury automobiles and automobile parts worldwide. Rolls-Royce Motors Cars Limited is the manufacturer of Rolls-Royce branded motor cars since 2003. Although the Rolls-Royce brand has been in use since 1906, the Rolls-Royce Motor Cars subsidiary of BMW AG has no relationship to Rolls-Royce branded vehicles produced prior to 2003. The Rolls-Royce Phantom four-door sedan was the first product offered for sale in 2003, Rolls-Royce Motor Cars Limited has been manufacturing Rolls-Royce branded cars since 2003. Current chief executive Torsten Müller-Ötvös joined the company in January 2010 and that year, the companys sales in China increased by 600%, meaning that it is now Rolls-Royces second largest market after the US. In 1998, Vickers decided to sell Rolls-Royce Motors, the most likely buyer was BMW, who already supplied engines and other components for Rolls-Royce and Bentley cars, but BMWs final offer of £340 million was beaten by Volkswagens £430 million. BMWs contract to supply engines and components to Rolls-Royce Motors allowed BMW to cancel the contract with 12 months notice, volkswagen would be unable to re-engineer the Rolls-Royce and Bentley vehicles to use other engines within that time frame. With the Rolls-Royce brand identification marks split between the two companies and Volkswagens engine supply in jeopardy, the two entered into negotiations. Volkswagen agreed to sell BMW the Spirit of Ecstasy and grill shape trademarks and BMW agreed to supplying engines. Rolls-Royce Motor Cars Limited became the manufacturer of Rolls-Royce branded cars in 2003. From 2010 – Ghost 4-door sedan, Rolls-Royce announced in September 2006 that it would develop a new four-door model named Ghost. The Ghost will be smaller than the previous Rolls-Royce automobile launched, only 20% of the components would be sourced from BMW F017 Series, and it will be positioned below the Phantom. On 4 March 2014, the new Ghost Series II was revealed to the public at the Geneva Motor Show and it has a facelift front with new LED headlights. The interior has had an update as well, from 2013 – Rolls-Royce Wraith coupé. Rolls-Royce Motor Cars launched a new car at the Geneva Motor Show on 5 March 2013, the new car, named the Rolls-Royce Wraith was a luxury coupe, with a long bonnet and a sleek roof line, and was a coupe version of the Ghost. It was powered by a 623 bhp, twin-turbocharged V12 engine connected to an eight-speed gearbox, deliveries were expected to begin by the end of 2013. Rolls-Royce had stated that the Wraith would be the most powerful Rolls-Royce motor car to that date, from 2015 – Rolls-Royce Dawn 2015 Rolls-Royce announced the production of SUV for the very first time in the company history. According to Rolls-Royce, the new SUV will set new standards among cars of this segment

BMW
–
Bayerische Motoren Werke AG, usually known under its abbreviation BMW, is a German luxury vehicle, motorcycle, and engine manufacturing company founded in 1916. It is one of the luxury automakers in the world. The company is a component of the Euro Stoxx 50 stock market index, headquartered in Munich, Bavaria, BMW owns Mini cars and is the parent company of Rolls-Royce Motor Cars. BMW was established as a business entity following a restructuring of the Rapp Motorenwerke aircraft manufacturing firm in 1912 named Aerowerke Gustav Otto, after the end of World War I in 1918, BMW was forced to cease aircraft-engine production by the terms of the Versailles Armistice Treaty. The company consequently shifted to production as the restrictions of the treaty started to be lifted in 1923. BMWs first significant aircraft engine, and commercial product of any sort, was the BMW IIIa inline-six liquid-cooled engine of 1918, known for good fuel economy, with German rearmament in the 1930s, the company again began producing aircraft engines for the Luftwaffe. The factory in Munich made ample use of forced labour, foreign civilians, prisoners of war, the few Me 262 A-1b test examples built used the more developed version of the 003 jet, recording an official top speed of 800 km/h. The first-ever four-engine jet aircraft flown were the sixth and eighth prototypes of the Arado Ar 234 jet reconnaissance-bomber. Through 1944 the 003s reliability improved, making it a power plant for air frame designs competing for the Jägernotprogramms light fighter production contract. Which was won by the Heinkel He 162 Spatz design, the BMW003 aviation turbojet was also under consideration as the basic starting point for a pioneering turboshaft powerplant for German armored fighting vehicles in 1944–45, as the GT101. Towards the end of the Third Reich, BMW developed some military aircraft projects for the Luftwaffe, the BMW Strahlbomber, the BMW Schnellbomber and the BMW Strahljäger, but none of them were built. By the year 1958, the division of BMW was in financial difficulties. It was decided to carry on by trying to cash in on the current economy car boom exploited so successfully by German ex-aircraft manufacturers such as Messerschmitt, BMW bought the rights to manufacture the Italian Iso Isetta. BMWs version of the cars were to be powered by a modified form of BMWs motorcycle engine. This was moderately successful and helped the company get back on its feet, since 1959, the controlling majority shareholder of the BMW Aktiengesellschaft has been the Quandt family, which owns about 46% of the stock. The rest is in public float, BMW acquired the Hans Glas company based in Dingolfing, Germany, in 1966. Glas vehicles were badged as BMW until the company was fully absorbed. However, this factory was outmoded and BMWs biggest immediate gain was, according to themselves, the Glas factories continued to build a limited number of their existing models, while adding the manufacture of BMW front and rear axles until they could be closer incorporated into BMW

Crewe
–
Crewe /kruː/ is a railway town and civil parish within the borough of Cheshire East and the ceremonial county of Cheshire, England. The area has a population of 72,863, from 1946 until 2002 it was also the home of Rolls-Royce motor car production. The Pyms Lane factory on the west of the town now produces Bentley motor cars exclusively, Crewe is 158 miles north of London and 35 miles south of Manchester. Crewe was thus named after the station, rather than the other way round. The name derives from an Old Welsh word criu, meaning weir, Crewe was founded in the township of Monks Coppenhall which, with the township of Church Coppenhall, formed the ancient parish of Coppenhall. The railway station was named after the township of Crewe in which it was located, eventually, the township of Crewe became a civil parish in its own right also named, rather confusingly, Crewe. This civil parish changed its name to Crewe Green in 1974 to avoid confusion with the adjacent town, the railway station remained part of the civil parish of Crewe, outside the boundary of the municipal borough until 1936. An old, local riddle describes the unusual states of affairs, The place which is Crewe is not Crewe. Until the Grand Junction Railway company chose Crewe as the site for its works and railway station in the late 1830s. Winsford,7 miles to the north, had rejected an earlier proposal, Crewe railway station was built in fields near to Crewe Hall and was completed in 1837. A new town grew up, in the parishes of Monks Coppenhall and Church Coppenhall, alongside the increasingly busy station, GJR chief engineer Joseph Locke helped lay out the town. The town has a park, Queens Park, the land for which was donated by the London and North Western Railway. It has been suggested that their motivation was to prevent the rival Great Western Railway building a station on the site, the railway provided an endowment towards the building and upkeep of Christ Church. Until 1897 its vicar, non-conformist ministers and schoolteachers received concessionary passes, the company provided a doctors surgery with a scheme of health insurance. A gasworks was built and the water supply was adapted to provide drinking water. The railway also opened a market in 1854 and a clothing factory for John Compton who provided the company uniforms. During World War II the strategic presence of the railways and Rolls-Royce engineering works made Crewe a target for air raids. The borough lost 35 civilians to these, the worst raid was on 29 August 1940 when some 50 houses were destroyed, Crewe crater on Mars is named after the town of Crewe

Bentley
–
Bentley Motors Limited is a British manufacturer and marketer of luxury cars and SUVs—and a subsidiary of Volkswagen AG since 1998. The joining and eventual separation of Bentley and Rolls-Royce follows a series of mergers and acquisitions, beginning with the 1931 purchase by Rolls-Royce of Bentley, Rolls-Royce Motors was subsequently sold to engineering conglomerate, Vickers and in 1998, Vickers sold Rolls-Royce to Volkswagen AG. The aerospace company, Rolls-Royce Plc, ultimately sold both to BMW AG, at the DFP factory, in 1913, he noticed an aluminum paperweight and thought that aluminum might be a suitable replacement for cast iron to fabricate lighter pistons. The first Bentley aluminum pistons were fitted to Sopwith Camel aero engines during World War I, in August 1919, W. O. registered Bentley Motors Ltd. and in October he exhibited a car chassis, with dummy engine, at the London Motor Show. Ex–Royal Flying Corps officer Clive Gallop designed an innovative 4 valves per cylinder engine for the chassis, by December the engine was built and running. Delivery of the first cars was scheduled for June 1920, the durability of the first Bentley cars earned widespread acclaim and they competed in hill climbs and raced at Brooklands. Bentleys first major event was the 1922 Indianapolis 500, a race dominated by specialized cars with Duesenberg racing chassis and they entered a modified road car driven by works driver, Douglas Hawkes, accompanied by riding mechanic, H. S. Bertie Browning. Hawkes completed the full 500 miles and finished 13th with an speed of 74.95 mph after starting in 19th position. The team was rushed back to England to compete in the 1922 RAC Tourist Trophy. In ironic reference to his heavyweight boxers stature, Captain Woolf Barnato was nicknamed Babe, in 1925, he acquired his first Bentley, a 3-litre. With this car he won numerous Brooklands races, just a year later he acquired the Bentley business itself. The Bentley enterprise was always underfunded, but inspired by the 1924 Le Mans win by John Duff and Frank Clement, Barnato had incorporated Baromans Ltd in 1922, which existed as his finance and investment vehicle. Via Baromans, Barnato initially invested in excess of £100,000, saving the business, a financial reorganisation of the original Bentley company was carried out and all existing creditors paid off for £75,000. Existing shares were devalued from £1 each to just 1 shilling, Barnato held 149,500 of the new shares giving him control of the company and he became chairman. Barnato injected further cash into the business, £35,000 secured by debenture in July 1927, £40,000 in 1928, with renewed financial input, W. O. Bentley was able to design another generation of cars. The Bentley Boys were a group of British motoring enthusiasts that included Woolf Barnato, Sir Henry Tim Birkin, steeple chaser George Duller, aviator Glen Kidston, sammy Davis, and Dr Dudley Benjafield. The Bentley Boys, favored Bentley cars, many were independently wealthy and often had a military background. They kept the reputation for high performance alive, Bentley was noted for its four consecutive victories at the 24 Hours of Le Mans from 1927 to 1930

Volkswagen Group
–
Volkswagen Group, or Volkswagen Aktiengesellschaft, shortly VW AG, is a German multinational automotive manufacturing company headquartered in Wolfsburg, Lower Saxony, Germany. It designs, manufactures and distributes passenger and commercial vehicles, motorcycles, engines, in 2016, it was the largest automaker in the world with sales of 10.3 million units, overtaking Toyota. It has maintained the largest market share in Europe for over two decades and it ranked seventh in the 2016 Fortune Global 500 list of the worlds largest companies. It is divided into two divisions, the Automotive Division and the Financial Services Division, and has approximately 340 subsidiary companies. VW also has two major joint-ventures in China, the company has operations in approximately 150 countries and operates 100 production facilities across 27 countries. Volkswagen was founded in 1937 to manufacture the car which would become known as the Beetle, the companys production grew rapidly in the 1950s and 1960s, and in 1965 it acquired Auto Union, which subsequently produced the first post-war Audi models. Volkswagen launched a new generation of front-wheel drive vehicles in the 1970s, including the Passat, Polo and Golf, the companys operations in China have grown rapidly in the past decade with the country becoming its largest market. It has been traded in the United States via American depositary receipts since 1988, Volkswagen delisted from the London Stock Exchange in 2013. The state of Lower Saxony holds 12. 7% of the companys shares, Volkswagen held a 19. 9% non-controlling shareholding in Suzuki between 2009 and 2015. An international arbitration court ordered Volkswagen to sell the back to Suzuki. Suzuki paid $3. 8bn to complete the stock buy-back just hours prior to a scandal about emissions violations engulfing Volkswagen. Volkswagen was founded on 28 May 1937 in Berlin as the Gesellschaft zur Vorbereitung des Deutschen Volkswagens mbH by the National Socialist Deutsche Arbeitsfront. The purpose of the company was to manufacture the Volkswagen car, originally referred to as the Porsche Type 60, then the Volkswagen Type 1 and this vehicle was designed by Ferdinand Porsches consulting firm, and the company was backed by the support of Adolf Hitler. On 16 September 1938, Gezuvor was renamed Volkswagenwerk GmbH, only a small number of Type 60 Volkswagens were made during this time. The Fallersleben plant also manufactured the V-1 flying bomb, making the plant a major bombing target for the Allied forces, however, no British car manufacturer was interested, the vehicle does not meet the fundamental technical requirement of a motor-car. It is quite unattractive to the average buyer, to build the car commercially would be a completely uneconomic enterprise. In 1948, the Ford Motor Company of USA was offered Volkswagen, but Ernest Breech, as part of the Industrial plans for Germany, large parts of German industry, including Volkswagen, were to be dismantled. Total German car production was set at a maximum of 10% of the 1936 car production numbers

Eden Project
–
The Eden Project is a popular visitor attraction in Cornwall, England. Inside the two biomes are plants that are collected from many diverse climates and environments, the project is located in a reclaimed Kaolinite pit, located 2 km from the town of St Blazey and 5 km from the larger town of St Austell, Cornwall. The complex is dominated by two huge enclosures consisting of adjoining domes that house thousands of plant species, and each enclosure emulates a natural biome, the biomes consist of hundreds of hexagonal and pentagonal, inflated, plastic cells supported by steel frames. The largest of the two biomes simulates a Rainforest environment and the second, a Mediterranean environment, the project was conceived by Tim Smit and designed by architect Nicholas Grimshaw and engineering firm Anthony Hunt and Associates. Land use consultants led the masterplan and landscape design, the project took 2½ years to construct and opened to the public on 17 March 2001. At the bottom of the pit are two covered biomes, The Tropical Biome, covers 1.56 ha and measures 55 m high,100 m wide, and 200 m long. It is used for plants, such as fruiting banana plants, coffee, rubber and giant bamboo. The Mediterranean Biome covers 0.654 ha and measures 35 m high,65 m wide and it houses familiar warm temperate and arid plants such as olives and grape vines and various sculptures. The Outdoor Gardens represent the regions of the world with plants such as tea, lavender, hops, hemp and sunflowers. The covered biomes are constructed from a steel with mostly hexagonal external cladding panels made from the thermoplastic ETFE. Glass was avoided due to its weight and potential dangers, the cladding panels themselves are created from several layers of thin UV-transparent ETFE film, which are sealed around their perimeter and inflated to create a large cushion. The resulting cushion acts as a blanket to the structure. The ETFE material is resistant to most stains, which simply wash off in the rain, if required, cleaning can be performed by abseilers. Although the ETFE is susceptible to punctures, these can be fixed with ETFE tape. The structure is completely self-supporting, with no internal supports, the panels vary in size up to 9 m across, with the largest at the top of the structure. The ETFE technology was supplied and installed by the firm Vector Foiltec, the steel spaceframe and cladding package was designed, supplied and installed by MERO PLC, who also jointly developed the overall scheme geometry with the architect, Nicholas Grimshaw & Partners. The entire build project was managed by McAlpine Joint Venture, the Core is the latest addition to the site and opened in September 2005. Accordingly, the building has taken its inspiration from plants, most noticeable in the form of the timber roof

Cornwall
–
Cornwall is a ceremonial county and unitary authority area of England within the United Kingdom. It is bordered to the north and west by the Celtic Sea, to the south by the English Channel, Cornwall has a population of 551,700 and covers an area of 3,563 km2. Cornwall forms the westernmost part of the south-west peninsula of the island of Great Britain, and this area was first inhabited in the Palaeolithic and Mesolithic periods. It continued to be occupied by Neolithic and then Bronze Age peoples, there is little evidence that Roman rule was effective west of Exeter and few Roman remains have been found. In the mid-19th century, however, the tin and copper mines entered a period of decline, subsequently, china clay extraction became more important and metal mining had virtually ended by the 1990s. Traditionally, fishing and agriculture were the important sectors of the economy. Railways led to a growth of tourism in the 20th century, however, the area is noted for its wild moorland landscapes, its long and varied coastline, its attractive villages, its many place-names derived from the Cornish language, and its very mild climate. Extensive stretches of Cornwalls coastline, and Bodmin Moor, are protected as an Area of Outstanding Natural Beauty, Cornwall is the homeland of the Cornish people and is recognised as one of the Celtic nations, retaining a distinct cultural identity that reflects its history. Some people question the present constitutional status of Cornwall, and a nationalist movement seeks greater autonomy within the United Kingdom in the form of a devolved legislative Cornish Assembly. On 24 April 2014 it was announced that Cornish people will be granted minority status under the European Framework Convention for the Protection of National Minorities. The modern English name Cornwall derives from the concatenation of two ancient demonyms from different linguistic traditions, Corn- records the native Brythonic tribe, the Cornovii. The Celtic word kernou is cognate with the English word horn. -wall derives from the Old English exonym walh, the Ravenna Cosmography first mentions a city named Purocoronavis in the locality. This is thought to be a rendering of Duro-cornov-ium, meaning fort of the Cornovii. The exact location of Durocornovium is disputed, with Tintagel and Carn Brea suggested as possible sites, in later times, Cornwall was known to the Anglo-Saxons as West Wales to distinguish it from North Wales. The name appears in the Anglo-Saxon Chronicle in 891 as On Corn walum, in the Domesday Book it was referred to as Cornualia and in c.1198 as Cornwal. Other names for the county include a latinisation of the name as Cornubia, the present human history of Cornwall begins with the reoccupation of Britain after the last Ice Age. The area now known as Cornwall was first inhabited in the Palaeolithic and Mesolithic periods and it continued to be occupied by Neolithic and then Bronze Age people. The Common Brittonic spoken at the time developed into several distinct tongues

Hectare
–
The hectare is an SI accepted metric system unit of area equal to 100 ares and primarily used in the measurement of land as a metric replacement for the imperial acre. An acre is about 0.405 hectare and one hectare contains about 2.47 acres, in 1795, when the metric system was introduced, the are was defined as 100 square metres and the hectare was thus 100 ares or 1⁄100 km2. When the metric system was further rationalised in 1960, resulting in the International System of Units, the are was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI units, the metric system of measurement was first given a legal basis in 1795 by the French Revolutionary government. At the first meeting of the CGPM in 1889 when a new standard metre, manufactured by Johnson Matthey & Co of London was adopted, in 1960, when the metric system was updated as the International System of Units, the are did not receive international recognition. The units that were catalogued replicated the recommendations of the CGPM, many farmers, especially older ones, still use the acre for everyday calculations, and convert to hectares only for official paperwork. Farm fields can have long histories which are resistant to change, with names such as the six acre field stretching back hundreds of years. The names centiare, deciare, decare and hectare are derived by adding the standard metric prefixes to the base unit of area. The centiare is a synonym for one square metre, the deciare is ten square metres. The are is a unit of area, equal to 100 square metres and it was defined by older forms of the metric system, but is now outside of the modern International System of Units. It is commonly used to measure real estate, in particular in Indonesia, India, and in French-, Portuguese-, Slovakian-, Serbian-, Czech-, Polish-, Dutch-, in Russia and other former Soviet Union states, the are is called sotka. It is used to describe the size of suburban dacha or allotment garden plots or small city parks where the hectare would be too large, the decare is derived from deka, the prefix for 10 and are, and is equal to 10 ares or 1000 square metres. It is used in Norway and in the former Ottoman areas of the Middle East, the hectare, although not strictly a unit of SI, is the only named unit of area that is accepted for use within the SI. The United Kingdom, United States, Burma, and to some extent Canada instead use the acre, others, such as South Africa, published conversion factors which were to be used particularly when preparing consolidation diagrams by compilation. In many countries, metrication redefined or clarified existing measures in terms of metric units, non-SI units accepted for use with the International System of Units

Green roof
–
A green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. It may also include additional layers such as a barrier and drainage. Container gardens on roofs, where plants are maintained in pots, are not generally considered to be true green roofs, rooftop ponds are another form of green roofs which are used to treat greywater. They effectively utilize the natural functions of plants to filter water, the term green roof may also be used to indicate roofs that use some form of green technology, such as a cool roof, a roof with solar thermal collectors or photovoltaic panels. See the PDF at for more information, Green roofs not only retain rainwater, but also moderate the temperature of the water and act as natural filters for any of the water that happens to run off. Many green roofs are installed to comply with regulations and government fees. In areas with combined systems, heavy storms can overload the wastewater system and cause it to flood. Green roofs decrease the amount of runoff and slow the rate of runoff from the roof. It has been found that they can retain up to 75% of rainwater, gradually releasing it back into the atmosphere via condensation and transpiration, combating the urban heat island effect is another reason for creating a green roof. Traditional building materials soak up the radiation and re-emit it as heat. On Chicagos City Hall, by contrast, which features a roof, roof temperatures on a hot day are typically 1. 4–4.4 °C cooler than they are on traditionally roofed buildings nearby. Green roofs are becoming common in Chicago, as well as in Atlanta, Portland, and other United States cities, Green roofs are a type of low impact development. In the case of Chicago, the city has passed codes offering incentives to builders who put green roofs on their buildings. Following this and other studies, it has now estimated that if all the roofs in a major city were greened. Green roofs also provide habitats for plants, insects, and animals that otherwise have limited space in cities. Even in high-rise urban settings as tall as 19 stories, it has found that green roofs can attract beneficial insects, birds. Rooftop greenery complements wild areas by providing stepping stones for songbirds, migratory birds, an additional environmental benefit of greens roofs is the ability to sequester carbon. Carbon is the component of plant matter and is naturally absorbed by plant tissue

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 updated to 470 and 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 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 Sedums are Sedum acre, Sedum album, Sedum dasyphyllum, Sedum reflexum and Sedum hispanicum, Sedum demonstrates a wide variation in chromosome numbers, and polyploidy is common. Chromosome number is an important taxonomic feature, linnaeus originally described 16 species of European Sedum. There are now thought to be approximately 55 European species, in particular, Sedum spathulifolium is the host plant of the endangered San Bruno elfin butterfly of San Mateo County, California. Many sedums are cultivated as garden plants, due to their interesting and attractive appearance, the various species differ in their requirements, some are cold-hardy but do not tolerate heat, some require heat but do not tolerate cold. Sedum reflexum, known as prickmadam, stone orpine, or crooked yellow stonecrop, is used as a salad leaf or herb in Europe. It has a slightly astringent sour taste, Sedum divergens, known as spreading stonecrop, was eaten by First Nations people in Northwest British Columbia. The plant is used as a salad herb by the Haida and it is common in the Nass Valley of British Columbia. Biting Stonecrop contains high quantities of alkaloids, which give it a sharp, peppery, acrid taste. Sedum can be used to provide a covering in green roofs. Fords Dearborn Truck Plant’s living roof has 450,000 square feet of sedum, rolls-Royce Motor Cars plant in Goodwood, England, has a 242,000 square feet roof complex covered in Sedum, the largest in the United Kingdom. Nintendo of Americas roof is covered in some 75,000 square feet of Sedum, media related to Sedum at Wikimedia Commons Data related to Sedum at Wikispecies Sedum.
