The pansy is a group of large-flowered hybrid plants cultivated as garden flowers.

The common names "pansy" and "violet" are often used interchangeably. When a distinction is made, plants considered to be pansies have four petals pointing upwards, and only one pointing down. Violets have three petals pointing up and two pointing down. Thus Viola cornuta is commonly referred to as a pansy. Source
