Fennel is native to southern Europe and the Mediterranean region, where it has been used for centuries. It is a highly aromatic and flavorful yellow-flowered plant of the parsley family, with feathery leaves, not to mention that people always choose it for its sweet, licorice-like flavor with citrus notes. As a matter of fact, fennel contains a combination of phytonutrients that gives it strong antioxidant properties. It has also been used to treat various digestive symptoms, including heartburn, gas and bloating. If you want to prepare something delicious with this plant, try roasting it with other root vegetables or you can simply slice it and then add it raw to green salads.
