Rosinweed ("Silphium") is a genus of about 20 species of flowering plants in the family Asteraceae, native to eastern North America. They are herbaceous perennial plants growing to 0.5-4 m tall, with yellow (rarely white) flowerheads. The name of the genus comes from the Ancient Greek word for a North African plant whose identity has been lost, though we know its gum or juice was prized by the ancients as a medicine and a condiment. [cite web | url = http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=130361 | title = Silphium | work = Flora of North America] For a discussion of the ancient plant, see silphium.
