Pansy Chang
The garden pansy (''Viola'' × ''wittrockiana'') is a type of large-flowered hybrid plant cultivated as a garden flower. It is derived by hybridization from several species in the section ''Melanium'' ("the pansies") of the genus ''Viola'', particularly '' Viola tricolor'', a wildflower of Europe and western Asia known as heartsease. It is sometimes known as ''Viola tricolor'' var. ''hortensis'', but this scientific name is ambiguous. While ''Viola tricolor'' var. ''hortensis'' Groenland & Rümpler is a synonym of ''Viola'' × ''wittrockiana'', ''Viola tricolor'' var. ''hortensis'' DC. refers to a horticultural variety of wild pansy ('' Viola tricolor'' without interspecific hybridization) that had been illustrated in '' Flora Danica'' in 1777 before the existence of ''Viola'' × ''wittrockiana''. The chromosome number of ''Viola'' × ''wittrockiana'' is 2n = 44–52, with most cultivars being 2n = 48. The flower is in diameter and has two slightly overlapping upper ...

Gams coined the terms ' biocoenology' and ' phytocoenology' in his 1918 PhD thesis.Rabotnov TA. 1970-1979Phytocoenology.In: The Great Soviet Encyclopedia, 3rd ed.

Purple Pansy
Purple is any of a variety of colors with hue between red and blue. In the RGB color model used in computer and television screens, purples are produced by mixing red and blue light. In the RYB color model historically used by painters, purples are created with a combination of red and blue pigments. In the CMYK color model used in printing, purples are made by combining magenta pigment with either cyan pigment, black pigment, or both. Purple has long been associated with royalty, originally because Tyrian purple dye, made from the mucus secretion of a species of snail, was extremely expensive in antiquity. Purple was the color worn by Roman magistrates; it became the imperial color worn by the rulers of the Byzantine Empire and the Holy Roman Empire, and later by Roman Catholic bishops. Similarly in Japan, the color is traditionally associated with the emperor and aristocracy. According to contemporary surveys in Europe and the United States, purple is the color most oft ...

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. Similar awards The award should not be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
