Fennel (Foeniculum vulgare) is a flowering plant species in the carrot family.[2] It is a hardy, perennial herb[3] with yellow flowers and feathery leaves.[4] It is indigenous to the shores of the Mediterranean but has become widely naturalized in many parts of the world, especially on dry soils near the sea-coast and on riverbanks.
It is a highly flavorful herb used in cooking and, along with the similar-tasting anise, is one of the primary ingredients of absinthe. Florence fennel or finocchio (UK: /fɪˈnɒkioʊ/, US: /-ˈnoʊk-/, Italian: [fiˈnɔkkjo]) is a selection with a swollen, bulb-like stem base that is used as a vegetable.
