Ditaxis heterantha is a member of the plant family Euphorbiaceae and grows wild in Guanajuato, Mexico, where it is known as
azafrán,
azafrancillo, or
azafrán de bolita and has several culinary uses, including as a substitute for saffron.
Ditaxis heterantha is not related to true saffron (
Crocus sativus) nor to safflower (
Carthamus tinctorius), which also is used as a saffron substitute.
