Ferula is a genus of about 170 species of flowering plants in the family Apiaceae, native to the Mediterranean region east to central Asia, mostly growing in arid climates. They are herbaceous perennial plants growing to 1-4 m tall, with stout, hollow, somewhat succulent stems. The leaves are tripinnate or even more finely divided, with a stout basal sheath clasping the stem.

(Latin) literally, this word means "fennel"; it comes to indicate any kind of cane or stick, including those used to punish slaves and children.
