Pansy

The garden pansy 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. Some of these hybrids are referred to as Viola × wittrockiana Gams ex Nauenb. & Buttler. For simplicity, the older name Viola tricolor var. hortensis is often used.

The garden pansy flower is two to three inches 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 nine inches in height, and prefers sun to varying degrees and well-draining soils.
