Is a genus of flowering plant in the violet family Violaceae. Viola are most often spring blooming with chasmogamous flowers with well-developed petals pollinated by insects. After flowering, fruit capsules are produced that split open by way of three valves. On drying, the capsules may eject seeds with considerable force to distances of several meters. The nutlike seeds have straight embryos, flat cotyledons, and soft fleshy endosperm that are oily. The seeds of some species have elaiosomes and are dispersed by ants.
