Chrozophora

Chrozophora is a plant genus of the family Euphorbiaceae first described as a genus in 1824. It comprises monoecious herbs or undershrubs. The genus is widespread across Europe, Africa, and Asia. Chrozophora tinctoria produced the blue-purple colorant 'turnsole' used in medieval illuminated manuscripts and as a food colorant moved to other genera (Codiaeum and Mallotus)
