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 petals, two side petals, and a single bottom petal with a slight beard emanating from the flower's center. These petals are usually white or yellow, purplish, or blue. The plant may grow to in height, and prefers sun to varying degrees and well-draining soils. Names and terminology English common names, such as "pansy", "viola" and "violet" may be used interchangeably. One possible distinction is that plants considered to be "pansies" are classified in Viola sect. Melanium, and have four petals pointing upwards (the two side petals point upwards), and only one pointing down, whereas those considered to be "violets" are classified in Viola sect. Viola, and have two petals pointing up and three pointing down. Another possible distinction is made by the American Violet Society – the International Cultivar Registration Authority for the genus Viola. It divides cultivated varieties (cultivars) in Viola sect. Melanium into four subgroups: B1 – pansies, B2 – violas, B3 – violettas and B4 – cornuta hybrids. On this classification, modern "pansies" differ from the other three subgroups by possessing a well-defined "blotch" or "eye" in the middle of the flower. Modern horticulturalists tend to use the term "pansy" for those multi-coloured large-flowered hybrids that are grown for bedding purposes every year, while "viola" is usually reserved for smaller, more delicate annuals and perennials. Etymology The name "pansy" is derived from the French word pensée, "thought", and was imported into Late Middle English as a name of Viola in the mid-15th century, as the flower was regarded as a symbol of remembrance.
