Prunus × Cistena
''Prunus'' × ''cistena'', the purple leaf sand cherry or dwarf red-leaf plum, is a hybrid species of ''Prunus'', the result of a cross between ''Prunus cerasifera'' (cherry plum or myrobalan plum) and ''Prunus pumila'' (sand cherry). A leggy bush or shrubby tree, it typically reaches a height of 1.5–2.5 meters and has a useful life of 10–20 years. The fruits are edible, if strong-tasting. Some people make jams or preserves from them. It is not advisable to eat the pits. Frost-tolerant, purple leaf sand cherries can be grown up to USDA Hardiness Zone 2a. Commercial specimens are typically grafted to a rootstock from any of a number of other species, which will influence their growth form and final height. There are also a limited selection of cultivars available. ''Prunus'' × ''cistena'' was developed by Niels Ebbesen Hansen in 1910. In 1993 it won the Royal Horticultural Society The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of Lon ...

Niels Ebbesen Hansen
Niels Ebbesen Hansen (January 4, 1866 – October 5, 1950) was a Danish-American horticulturist, botanist, and agricultural explorer for the United States Department of Agriculture and the state of South Dakota. He searched the harsh environments of northern Scandinavia, Siberia, Manchuria, and the dry steppes of the Volga for plant stock that could flourish on the upper Great Plains. Biography Niels Ebbesen Hansen was born the youngest of three children in Lustrupholm, Denmark, a small farm, in Ribe County, Denmark. He was the son of Danish-born muralist Andreas Hansen and Bodil Midtgaard. Hansen's mother died when he was a year and a half old. His father married Katrine Petersen two years later. Andreas Hansen emigrated to the United States in 1872 and sent for Katrine and Niels the following year. In 1876, the family moved to Des Moines, Iowa. Hansen left high school at the beginning of his junior year to work as a messenger for Iowa Secretary of State John A.T. Hull. He s ...

Bernhard Adalbert Emil Koehne
Bernhard Adalbert Emil Koehne (12 February 1848 – 12 October 1918) was a German botanist and dendrologist born near Striegau, a town known today as Strzegom, Poland. Koehne was a professor of botany in Berlin and was a leading authority of the plant family Lythraceae. In Adolf Engler's treatise ''Das Pflanzenreich'' ("The Plant Kingdom"), he was author of the chapter on Lythraceae. He also made important contributions involving Lythraceae to Engler and Karl Prantl's ''Die Natürlichen Pflanzenfamilien'' ("The Natural Plant Families"), as well as to Karl Friedrich Philipp von Martius' ''Flora Brasiliensis''. Another noted written effort by Koehne was the 1893 ''Deutsche Dendrologie'' ("German Dendrology"). Two plant genera have been named in his honor; '' Koehneola'' from Cuba, in the (family Asteraceae) was named in 1901, and ''Koehneria ''Koehneria'' is a monotypic genus of flowering plants belonging to the family Lythraceae. The only species is ''Koehneria madagas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid Species
Hybrid speciation is a form of speciation where hybridization between two different species leads to a new species, reproductively isolated from the parent species. Previously, reproductive isolation between two species and their parents was thought to be particularly difficult to achieve, and thus hybrid species were thought to be very rare. With DNA analysis becoming more accessible in the 1990s, hybrid speciation has been shown to be a somewhat common phenomenon, particularly in plants. In botanical nomenclature, a hybrid species is also called a nothospecies. Hybrid species are by their nature polyphyletic. Ecology A hybrid may occasionally be better fitted to the local environment than the parental lineage, and as such, natural selection may favor these individuals. If reproductive isolation is subsequently achieved, a separate species may arise. Reproductive isolation may be genetic, ecological, behavioral, spatial, or a combination of these. If reproductive isolation fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prunus
''Prunus'' is a genus of trees and shrubs, which includes (among many others) the fruits plums, cherries, peaches, nectarines, apricots, and almonds. Native to the North American temperate regions, the neotropics of South America, and the paleotropics of Asia and Africa, 430 different species are classified under ''Prunus''. Many members of the genus are widely cultivated for their fruit and for decorative purposes. ''Prunus'' fruit are drupes, or stone fruits. The fleshy mesocarp surrounding the endocarp is edible while the endocarp itself forms a hard, inedible shell called the pyrena ("stone" or "pit"). This shell encloses the seed (or "kernel") which is edible in many species (such as almonds) but poisonous in others (such as apricots). Besides being eaten off the hand, most ''Prunus'' fruit are also commonly used in processing, such as jam production, canning, drying, and seeds for roasting. Botany Members of the genus can be deciduous or evergreen. A few species ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prunus Pumila
''Prunus pumila'', commonly called sand cherry, is a North American species of cherry in the rose family. It is widespread in eastern and central Canada from New Brunswick west to Saskatchewan and the northern United States from Maine to Montana, south as far as Colorado, Kansas, Indiana, and Virginia, with a few isolated populations in Tennessee and Utah. It grows in sandy locations such as shorelines and dunes. ''Prunus pumila'' is a deciduous shrub that grows to tall depending on the variety. It forms dense clonal colonies by sprouts from the root system. The leaves are leathery, long, with a serrated margin. The flowers are in diameter with five white petals and 25–30 stamens. They are produced in small clusters of two to four. The fruit is a small cherry in diameter, ripening to dark purple in early summer.Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''.

Preserves
Fruit preserves are preparations of fruits whose main preserving agent is sugar and sometimes acid, often stored in glass jars and used as a condiment or spread. There are many varieties of fruit preserves globally, distinguished by the method of preparation, type of fruit used, and place in a meal. Sweet fruit preserves such as jams, jellies, and marmalades are often eaten at breakfast with bread or as an ingredient of a pastry or dessert, whereas more savory and acidic preserves made from " vegetable fruits" such as tomato, squash or zucchini, are eaten alongside savory foods such as cheese, cold meats, and curries. Techniques There are several techniques of making jam, with or without added water. One factor depends on the natural pectin content of the ingredients. When making jam with low pectin fruits like strawberries either high pectin fruit like orange can be added, or additional pectin in the form of pectin powder, citric acid or citrus peels. Often the fruit will be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USDA 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 ...

List Of Award Of Garden Merit Flowering Cherries
The following tree species and cultivars in the genus ''Prunus'' (family Rosaceae) currently (2016) hold the Royal Horticultural Society's Award of Garden Merit. All are described as flowering or ornamental cherries, though they have mixed parentage, and some have several or unknown parents. They are valued for their spring blossom, and in some cases ornamental fruit and bark. This list does not include the edible, or culinary, fruit trees in the genus ''Prunus'' (cherries, peaches, almonds, plums etc.). Dimensions shown are the maximum, which can often be restricted by regular pruning. Many cultivars also lend themselves to bonsai treatment.

Award Of Garden Merit
The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. History The Award of Garden Merit is a mark of quality awarded, since 1922, to garden plants (including trees, vegetables and decorative plants) by the United Kingdom, Royal Horticultural Society (RHS). Awards are made annually after plant trials intended to judge the plants' performance under UK growing conditions. Trials may last for one or more years, depending on the type of plant being analyzed, and may be performed at Royal Horticulture Society Garden in Wisley and other gardens or after observation of plants in specialist collections. Trial reports are made available as booklets and on the website. Awards are reviewed annually in case plants have become unavailable horticulturally, or have been superseded by better cultivars.
