Fennel is a member of the carrot family, though it’s not a root vegetable. The base of its long stalks weave together to form a thick, crisp bulb that grows above ground. Above the bulb, at the tip of the stalks, it has light, feathery leaves that resemble dill. When it goes to seed, fennel also produces small yellow flowers among the leaves. Every part of it is edible, from the bulb to the flowers, and it can be eaten raw or cooked.
