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 ...

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). ...

Greenland
Greenland ( kl, Kalaallit Nunaat, ; da, Grønland, ) is an island country in North America that is part of the Kingdom of Denmark. It is located between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Greenland is the world's largest island. It is one of three constituent countries that form the Kingdom of Denmark, along with Denmark and the Faroe Islands; the citizens of these countries are all citizens of Denmark and the European Union. Greenland's capital is Nuuk. Though a part of the continent of North America, Greenland has been politically and culturally associated with Europe (specifically Norway and Denmark, the colonial powers) for more than a millennium, beginning in 986.The Fate of Greenland's Vikings , by Dale Mackenzie Brown, ''Archaeological Institute of America'', ...

Davis Strait
Davis Strait is a northern arm of the Atlantic Ocean that lies north of the Labrador Sea. It lies between mid-western Greenland and Baffin Island in Nunavut, Canada. To the north is Baffin Bay. The strait was named for the English explorer John Davis (1550–1605), who explored the area while seeking a Northwest Passage. By the 1650s it was used for whale hunting. Extent The International Hydrographic Organization defines the limits of the Davis Strait as follows: ''On the North.'' The Southern limit of Baffin Bay 70° North between Greenland and Baffin Island">Baffin Land]. ''On the East.'' The Southwest coast of Greenland. ''On the South.'' The parallel of 60th parallel north, 60° North between Greenland and Labrador. ''On the West.''

Northwest Passage
The Northwest Passage (NWP) is the sea route between the Atlantic and Pacific oceans through the Arctic Ocean, along the northern coast of North America via waterways through the Canadian Arctic Archipelago. The eastern route along the Arctic coasts of Norway and Siberia is accordingly called the Northeast Passage (NEP). The various islands of the archipelago are separated from one another and from Mainland Canada by a series of Arctic waterways collectively known as the Northwest Passages, Northwestern Passages or the Canadian Internal Waters. For centuries, European explorers, beginning with Christopher Columbus in 1492, sought a navigable passage as a possible trade route to Asia, but were blocked by North, Central, and South America, by ice, or by rough waters (e.g. Tierra del Fuego). An ice-bound northern route was discovered in 1850 by the Irish explorer Robert McClure. Scotsman John Rae explored a more southerly area in 1854 through which Norwegian Roald Amundsen f ...

John Davis (explorer)
John Davis ( – 29 December 1605) was one of the chief navigators of Queen Elizabeth I of England. He led several voyages to discover the Northwest Passage and served as pilot and captain on both Dutch and English voyages to the East Indies. He discovered the Falkland Islands in August 1592. Life and career Davis was born in the parish of Stoke Gabriel in Devon circa 1550, and spent his childhood in Sandridge Barton nearby. It has been suggested that he learned much of his seamanship as a child while playing boats along the river Dart, and went to sea at an early age. His childhood neighbours included Adrian Gilbert and Humphrey Gilbert and their half-brother Walter Raleigh. From early on, he also became friends with John Dee. He began pitching a voyage in search of the Northwest Passage to the queen's secretary Francis Walsingham in 1583. Two years later, in 1585, the secretary relented and funded the expedition, which traced Martin Frobisher, Frobisher's route to Greenland' ...

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 ...

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 ...
