Canna (plant)
''Canna'' or canna lily is the only genus of flowering plants in the family Cannaceae, consisting of 10 species.The Cannaceae of the World, H. Maas-van der Kamer & P.J.M. Maas, BLUMEA 53: 247-318 Cannas are not true lilies, but have been assigned by the APG II system of 2003 to the order Zingiberales in the monocot clade Commelinids, together with their closest relatives, the gingers, spiral gingers, bananas, arrowroots, heliconias, and birds of paradise. The plants have large foliage, so horticulturists have developed selected forms as large-flowered garden plants. Cannas are also used in agriculture as a source of starch for human and animal consumption. Khoshoo, T.N. & Guha, I. - Origin and Evolution of Cultivated Cannas. Vikas Publishing House Although plants of the tropics, most cultivars have been developed in temperate climates and are easy to grow in most countries of the world, as long as they receive at least 6–8 hours average sunlight during the summer, and ar ...

Canna 'Roi Humbert'
''Canna'' 'Roi Humbert' is an Italian Group canna cultivar; bronze foliage, ovoid shaped, spreading habit; oval stems, coloured purple; flowers are cupped, self-coloured scarlet, staminodes are large, edges ruffled, fully self-cleaning; seed is sterile, pollen is sterile; rhizomes are thick, up to 3 cm in diameter, coloured purple; tillering is average. Introduced by C. Sprenger, Dammann & Co, Naples, Italy, EU in 1908. C. 'Roi Humbert is the result of an F2 crossing, namely C. 'Madame Crozy' x C. ''flaccida'' produced C. 'Italia', then C. 'Madame Crozy ' was crossed with C. 'Italia'. This reinforced the characteristics of the Italian Group, as the cultivars derived from the C. ''flaccida'' cross have subsequently been named. Its rhizomes are heavily marked with maroon and have the shape of the C. ''indica'' side of the family, as do the leaves. The colour of the flower comes from the Crozy side, but the petal form is heavily influenced by the thinner and larger C. ''fla ...

List Of Canna Species
''Canna (plant), Canna'' species have been categorised by two different taxonomists in the course of the last three decades. They are Paulus Johannes Maria Maas, Paul Maas, from the Netherlands and Nobuyuki Tanaka from Japan.Tanaka, N. (2001) Taxonomic revision of the family Cannaceae in the New World and Asia. Both reduced the number of species from the 50-100 that had been accepted previously, and assigned most to being synonym (taxonomy), synonyms. Inevitably, there are some differences in their categorisations, and the individual articles on the species describe the differences. The reduction in the number of species is also confirmed by work done by Kress and Prince at the Smithsonian Institution, however, this only covers a subset of the species range.Prince, Linda M.* and W. John Kress. Smithsonian Institution Tanaka's 2001 ''Taxonomic revision of the family Cannaceae in the New World and Asia'' is one source of species names, allied with the proposal to conserve the name ...

List Of Canna Hybridists
The first hybridisation of Cannas was performed in 1848, and since then many Canna hybridizers have made their contribution to the genus over the centuries. This is a date ordered list of those people and their brief stories. 1848 Théodore Année A retired French diplomatic agent in America, the gentleman gardener Monsieur Théodore Année of Passy, France, brought back from his travels the seeds of several Canna species, and in 1848 he crossed C. ''glauca'' with C. ''indica'', so producing the first known and recorded Canna hybrid, C. x ''annaei'' André, now referred to as C. 'Annei'. Année was rapidly joined by many other enthusiasts and professional horticulturists as Canna hybrids enjoyed rapid popularity in France. In 1866 he retired to Nice, France, and from there released his last recorded cultivar, C. 'Prémices de Nice'. 1850s Jean Liabaud A resident of Lyon, France. 1850s E.

List Of Canna Cultivars
This list of ''Canna'' cultivars is a gallery of named cultivars of plants in the genus '' Canna'' that are representative of the various ''Canna'' cultivar groups (i.e., groups of very similar cultivars). Names of cultivars conform to the rules of the International Society for Horticultural Science (ISHS) Commission for Nomenclature and Cultivar Registration, as laid down in the International Code of Nomenclature for Cultivated Plants. They are registered with an International Cultivar Registration Authority (ICRA), which for the genus ''Canna'' is the Royal General Bulbgrowers' Association of the Netherlands (KAVB). Foliage group Cultivars, F1 and F2 hybrids, normally with small species-like flowers, but grown principally for their foliage. This group has occasionally been referred to as the Année Group, after the originator, Théodore Année, the world's first ''Canna'' hybridizer. However, the use of an accented character in the name creates problems, both in pronunciatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Horticultural Society
The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity. The RHS promotes horticulture through its five gardens at Wisley (Surrey), Hyde Hall (Essex), Harlow Carr (North Yorkshire), Rosemoor (Devon) and Bridgewater (Greater Manchester); flower shows including the Chelsea Flower Show, Hampton Court Palace Flower Show, Tatton Park Flower Show and Cardiff Flower Show; community gardening schemes; Britain in Bloom and a vast educational programme. It also supports training for professional and amateur gardeners. the president was Keith Weed and the director general was Sue Biggs CBE. History Founders The creation of a British horticultural society was suggested by John Wedgwood (son of Josiah Wedgwood) in 1800. His aims were fairly modest: he wanted to hold regular meetings, allowing the society's members the opportunity to present papers on their horticultural activities and discoveries, to enc ...

Mutation
In biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA. Mutations result from errors during DNA or viral replication, mitosis, or meiosis or other types of damage to DNA (such as pyrimidine dimers caused by exposure to ultraviolet radiation), which then may undergo error-prone repair (especially microhomology-mediated end joining), cause an error during other forms of repair, or cause an error during replication (translesion synthesis). Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce detectable changes in the observable characteristics (phenotype) of an organism. Mutations play a part in both normal and abnormal biological processes including: evolution, cancer, and the development of the immune system, including junctional diversity. Mutation is the ultimate source o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated variety ...

Luther Burbank
Luther Burbank (March 7, 1849 – April 11, 1926) was an American botanist, horticulturist and pioneer in agricultural science. He developed more than 800 strains and varieties of plants over his 55-year career. Burbank's varied creations included fruits, flowers, grains, grasses, and vegetables. He developed (but did not create) a spineless cactus (useful for cattle-feed) and the plumcot. Burbank's most successful strains and varieties included the Shasta daisy, the fire poppy (note possible confusion with the California wildflower, '' Papaver californicum'', which is also called a fire poppy), the "July Elberta" peach, the "Santa Rosa" plum, the "Flaming Gold" nectarine, the "Wickson" plum (named after the agronomist Edward J. Wickson), the freestone peach, and the white blackberry. A natural genetic variant of the Burbank potato with russet-colored skin later became known as the russet Burbank potato. This large, brown-skinned, white-fleshed potato has become the world's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
