Rose
A rose is either a woody perennial flowering plant of the genus ''Rosa'' (), in the family Rosaceae (), or the flower it bears. There are over three hundred species and tens of thousands of cultivars. They form a group of plants that can be erect shrubs, climbing, or trailing, with stems that are often armed with sharp prickles. Their flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe, North America, and northwestern Africa. Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Roses have acquired cultural significance in many societies. Rose plants range in size from compact, miniature roses, to climbers that can reach seven meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses. Etymology The name ''rose'' comes from L ...

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 ...

British North America
British North America comprised the colonial territories of the British Empire in North America from 1783 onwards. English overseas possessions, English colonisation of North America began in the 16th century in Newfoundland (island), Newfoundland, then further south at Roanoke Colony, Roanoke and Jamestown, Virginia, and more substantially with the founding of the Thirteen Colonies along the Atlantic coast of North America. The British Empire's colonial territories in North America were greatly expanded in connection with the Treaty of Paris (1763), which formally concluded the Seven Years' War, referred to by the English colonies in North America as the French and Indian War, and by the French colonies as . With the ultimate acquisition of most of New France (), Territorial evolution of North America since 1763, British territory in North America was more than doubled in size, and the exclusion of France also dramatically altered the political landscape of the continent.

Surveyor (surveying)
Surveying or land surveying is the technique, profession, art, and science of determining the terrestrial two-dimensional or three-dimensional positions of points and the distances and angles between them. A land surveying professional is called a land surveyor. These points are usually on the surface of the Earth, and they are often used to establish maps and boundaries for ownership, locations, such as the designed positions of structural components for construction or the surface location of subsurface features, or other purposes required by government or civil law, such as property sales. Surveyors work with elements of geodesy, geometry, trigonometry, regression analysis, physics, engineering, metrology, programming languages, and the law. They use equipment, such as total stations, robotic total stations, theodolites, GNSS receivers, retroreflectors, 3D scanners, LiDAR sensors, radios, inclinometer, handheld tablets, optical and digital levels, subsurface locators, d ...

Samuel Holland (surveyor)
Samuel Johannes Holland (1728 – 28 December 1801) was a Dutch-born Royal Engineer and first Surveyor General of British North America. Life in the Netherlands Holland was born in 1728 in Deventer, the Netherlands. He was baptised on 22 September 1729 in the small Lutheran Church in the Dutch town of Deventer, in the Province of Overijssel. In 1745, he entered the Dutch, or Staatse Leger artillery, and served during the War of the Austrian Succession. He was promoted to lieutenant in 1747. In 1749, Holland married Gertrude Hasse. They had one daughter, who is thought to have died in infancy. In 1754, having possibly made contact with the Duke of Richmond and leaving his wife behind in the Netherlands, Holland emigrated to England to seek advancement under the British flag. Early years in British North America In 1756, Holland, probably with Richmond's aid, became a lieutenant in the Royal Americans, coming to British North America where he would spend the rest of his l ...

Central Experimental Farm
The Central Experimental Farm (CEF), commonly known as the Experimental Farm, is an agricultural facility, working farm, and research centre of the Science and Technology Branch, formerly the Research Branch, of Agriculture and Agri-Food Canada. As the name indicates, this farm is centrally located in and now surrounded by the City of Ottawa, Ontario, Canada. The farm is a National Historic Site of Canada and most buildings are protected and preserved as heritage buildings. The CEF original intent was to perform scientific research for improvement in agricultural methods and crops. While such research is still being conducted, the park-like atmosphere of the CEF has become an important place of recreation and education for the residents of Ottawa. Furthermore, over the years several other departments and agencies have encroached onto the CEF property, such as Natural Resources Canada, National Defence ( HMCS Carleton on Dow's Lake), and the Ottawa Civic Hospital (helicopter pad). ...

Rosa × Kordesii
''Rosa'' × ''kordesii'', or ''Rosa kordesii'', is a red type of rose that arose naturally from hybridization followed by chromosome doubling. A hybrid between ''R. rugosa'' and ''R. lucieae'' was created called ''Rosa'' 'Max Graf', but it was diploid and nearly sterile, producing flowers but no fruit. This rose produced a few viable seeds as a result of self-pollination, and the seedlings that resulted were tetraploid instead of diploid, i.e., the chromosomes of both pollen and egg cells had been naturally duplicated. The tetraploid seedlings are amphidiploids. page 176 A selection with double deep pink flowers and repeat bloom, also called 'K01 AgCan' was released by W. Kordes' Söhne in 1951. These tetraploid roses interbreed readily with one another, but not with their diploid ancestors. Under the biological species concept, a new species name ''Rosa × kordesii'' was created for the tetraploid hybrid roses and their descendants. Amphidiploid roses can also be created de ...
