  Violet (plant) - Wikipedia, the free encyclopedia
Violets (Viola) are a genus of flowering plants in the family Violaceae, with around 400-500 species throughout the world, mainly in the temperate Northern Hemisphere but also in Hawaii, Australasia, and the Andes in South America.
One quirk of some violets is the elusive scent of their flowers; along with terpenes, a major component of the scent is a ketone compound called ionone, which temporarily desensitises the receptors in the nose; this prevents any further scent from being detected from the flower.
Australia is home to a number of violets, including Viola hederacea, Viola betonicifolia and Viola banksii, first collected by Joseph Banks and Daniel Solander on the Cook voyage to Botany Bay.
