What does Fennel look like?
Fennel is a tall, upright perennial herb that can reach up to 2.1 meters. Its stems are hollow and green, and the leaves are finely divided, threadlike, and feathery, resembling dill but even thinner. The plant produces flat-topped clusters (umbels) of many small, bright yellow flowers. The fruit, often called seeds, are small, grooved, and aromatic. The whole plant has a strong, sweet aroma similar to anise or licorice.
Where does Fennel come from?
Fennel is native to the Mediterranean coast but has spread widely and now grows wild in many temperate regions, especially near the sea and riverbanks. It has become naturalized in places like northern Europe, North America, Asia, and Australia. Ancient Greeks and Romans valued fennel for food, medicine, and as an insect repellent. Its name comes from Latin 'faeniculum', meaning 'little hay', and it has a long history in both culinary and medicinal traditions.
When and how Fennel blooms
Fennel grows best in dry, open sites and is propagated by seed or root crown. It flowers in compound umbels, producing many small yellow blossoms. The plant is cultivated for its edible bulb, leaves, and seeds. Florence fennel, a cultivated variety, forms a swollen, bulb-like stem base used as a vegetable. Fennel can self-seed and spread easily, sometimes becoming invasive in suitable climates.
How Fennel is used
All parts of fennel are used in cooking. The bulb is eaten raw or cooked, the leaves flavor salads, sauces, and fish, and the seeds are used as a spice in breads, desserts, and spice blends like Indian panch phoron and Chinese five-spice. In India, fennel seeds are chewed after meals as a digestive. Fennel is also used in absinthe and herbal teas. Traditional medicine and folklore have valued fennel for its aromatic and supposed health properties.
Kinds of Fennel
Florence fennel (finocchio) is a cultivated form with a bulb-like stem base, sweeter and more aromatic than wild fennel. Bronze fennel is grown for its decorative dark leaves. Fennel is sometimes confused with similar herbs like dill, caraway, and anise, but it is taller and has a stronger licorice scent. Wild fennel is common in many regions and can become invasive.
What Fennel means

In medieval Europe, it was one of the nine sacred herbs. Fennel is mentioned in poetry and was required to be grown on imperial farms by Charlemagne. In some places, it is considered a weed due to its ability to outcompete native plants.
