Most violas are small perennial plants, but a few are annual plants and some are small shrubs. The flower, variable in colour, but not red, usually grows singly on a stalk and has five petals, four arranged in unlike pairs. The leaves may grow on the same stalk as the flower (stemmed violets) or on separate stalks (stemless violets). Violas are used as food plants by the larvae of some Lepidoptera species. Viola flowers are edible, used in medicines, as a laxative, and the flowers are candied for decoration in jellies, etc.
