Silphium is a genus of North American plants in the sunflower tribe within the daisy family.[2][3]

Members of the genus, commonly known as rosinweeds, 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 it is known its gum or juice was prized by the ancients as a medicine and a condiment.[4]
