All parts of this herb are aromatic and delicious! The bulb, foliage, and herb seeds of the Fennel plant are widely used in many of the culinary traditions of the world. Sweet Fennel is widely cultivated, both in its native range and elsewhere, for its edible, strongly-flavored leaves and Fennel seeds. The flavor is similar to that of anise, though usually not so strong and more aromatic and sweeter.
