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. hortensisGroenland & Rümpler is a synonym of Viola × wittrockiana, V. tricolor var. hortensisDC. refers to a horticultural variety of wild pansy that had been illustrated in Flora Danica in 1777 before the existence of Viola × wittrockiana.
