Fennel (Foeniculum vulgare) is a plant species in the genus Foeniculum (treated as the sole species in the genus by most botanists). It is a hardy, perennial, umbelliferous herb, with yellow flowers and feathery leaves, grows wild in most parts of temperate Europe, but is generally considered indigenous to the shores of the Mediterranean, whence it spreads eastwards to India and even in England in Bedfont Lakes Country Park and Thurrock . It has followed, especially where Romans have colonized, and may be found growing wild in many parts of the world upon dry soils near the sea-coast and upon river-banks. It is a member of the family Apiaceae. It is a highly aromatic and flavorful herb with culinary and medicinal uses, and is one of the primary ingredients of absinthe. Fennel is used as a food plant by the larvae of some Lepidoptera species including the Mouse Moth and the Anise Swallowtail.
