Exacum affine

Exacum affine[3] known commercially as the Persian violet, is a species of plant in the family Gentianaceae. It is endemic to Socotra, part of Yemen, though its popularity and cultivation around the world have made it an occasional greenhouse weed. Its natural habitat is rocky areas. This is a small herbaceous biennial plant with dark green, ovate leaves. The small purple flowers have a yellow centre with fragrance.
