Ultraviolet photograph of a small yellow pansy flower. The flower appears quite plain and dark under ultraviolet light, though the dark lines around the center of the flower that stand out under visible light can still (just) be seen. Areas where the petals are missing colour and damaged are much more obvious under ultraviolet light as the white colour contrasts against the rest of the dark petals.
The pansy is a group of large-flowered hybrid plants cultivated as garden flowers. Pansies are derived from viola species Viola tricolor hybridized with other viola species, these hybrids are referred to as Viola × wittrockiana or less commonly Viola tricolor hortensis.
The pansy flower has two slightly overlapping upper petals, two side petals, and a single bottom petal with a slight beard emanating from the flower's center. The plant may grow to nine inches in height, and prefers sun to varying degrees and well-draining soils.
