The perennial herb, leaf fennel or sweet fennel is grown for its aromatic, aniseed-flavoured feathery leaves and its seeds, both of which are used to flavour dishes. The foliage is also very attractive and ornamental, and looks great in beds and borders. Florence fennel (Foeniculum vulgare var. dulce) is grown as a tender annual vegetable, loved for its crunchy, swollen stems. The leaves can also be used as a herb.
