Today, it is cultivated in gardens worldwide, particularly for its bluish foliage and often for its tolerance to dry and hot soils. Rue is a member of the Rutaceae family. Unfortunately, the knowledge base on the Ruta genus is somewhat incomplete. Some botanists suspect about 40 species[1] in this genus, but only 8 are currently known.
