Viola
Also called Violets
Viola is a genus of over 680 species of annual, perennial, and small shrubby plants, including the garden violets and pansies. Commonly grown members are typically cool-season, low-growing perennials or bedding annuals valued for their fragrant or colourful flowers.
Viola, commonly known as the violets, is a genus of flowering plants in the family Violaceae. It is the largest genus in the family, containing over 680 species. Most species are found in the temperate Northern Hemisphere; however, some are also found in widely divergent areas such as Hawaii, Australasia, and the Andes.
Some Viola species are perennial plants, some are annual plants, and a few are small shrubs. Many species, varieties and cultivars are grown in gardens for their ornamental flowers. In horticulture, the term pansy is normally used for those multi-colored large-flowered cultivars which are raised annually or biennially from seed and used extensively in bedding.
The international registration authority for the genus is the American Violet Society, where growers register new Viola cultivars. A coding system is used for cultivar description of ten horticultural divisions, such as Violet (Vt) and Violetta (Vtta). Examples include Viola 'Little David' (Vtta) and Viola 'Königin Charlotte' (Vt).
In this system violets (Vt) are defined as "stoloniferous perennials with small, highly fragrant, self-coloured purple, blue or white flowers in late winter and early spring".
The worldwide northern temperate distribution of the genus distinguishes it from the remaining largely tropical Violaceae genera, restricted to either Old World or New World species, while in the tropics the distribution is primarily in high mountainous areas. Centres of diversity occur mainly in the northern hemisphere, in mountainous regions of eastern Asia, Melanesia, and southern Europe, but also occur in the Andes and the southern Patagonian cone of South America. One of the highest species concentrations is in the former USSR. Australia is home to a number of Viola species, including Viola hederacea, Viola betonicifolia and Viola banksii, first collected by Joseph Banks and Daniel Solander on the Cook voyage to Botany Bay.
