Fennel is composed of a white or pale green bulb from which closely superimposed stalks are arranged. The stalks are topped with feathery green leaves near which flowers grow and produce fennel seeds. The bulb, stalk, leaves and seeds are all edible. Fennel belongs to the Umbellifereae family and is therefore closely related to parsley, carrots, dill and coriander.
Tightly wrap fresh fennel in a plastic bag and refrigerate for up to one week.
