Quick Summary

The genus Exacum comprises tropical plants from Asia and Africa, belonging to the Gentianaceae family. One notable species, E. affine, is an herbaceous biennial often cultivated in greenhouses for its attractive bluish to dark lavender flowers. The term "exacum" can refer to the genus itself or to any plant within this genus. The etymology traces back to the Latin word for a type of centaury, ultimately derived from Gaulish.1
