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. For a discussion of the ancient plant, see silphium.
