The garden pansy is a type of polychromatic large-flowered hybrid plant cultivated as a garden flower. It is derived by hybridization from several species in the section Melanium of the genus Viola, particularly V. tricolor, a wildflower of Europe and western Asia known as heartsease. It is sometimes known as V. tricolor var. hortensis, but this scientific name is suspect. While V. tricolor var. hortensis Groenland & Rümpler is a synonym of Viola × wittrockiana, V. tricolor var. hortensis DC. refers to a horticultural variety of wild pansy that had been illustrated in Flora Danica in 1777 before the existence of Viola × wittrockiana.

Viola is a genus of flowering plants in the violet 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.
