Fennel (*Foeniculum vulgare*) is a flowering plant in the carrot family (Apiaceae) native to the Mediterranean region and naturalized in many other parts of the world. It is grown for its feathery foliage, yellow flowers, aromatic seeds, and edible shoots or bulb-like base in some varieties.
Description
Fennel is a tall, aromatic herb with finely divided, feathery foliage, hollow stems, and umbels of small yellow flowers. It is a perennial in mild climates but is frequently treated as an annual in cooler regions. The plant typically reaches a height of about 1–2.5 m, depending on conditions and variety. Its flavour and aroma are often described as anise-like or licorice-like due to compounds including anethole.
Distribution and habitat
The species is native to southern Europe and the Mediterranean basin, including areas around the Mediterranean Sea. It has been widely introduced and is now naturalized in many regions, often in dry coastal habitats and along riverbanks. Some fennel varieties are considered invasive in parts of Australia and the United States.
Uses
Fennel is used as a culinary herb and spice, with the leaves, seeds, and tender stems commonly used in food. In some cultivated forms, the swollen base is eaten as a vegetable, and the plant is also grown ornamentally. Leaves, young shoots, stems, seeds, and in some types the bulb-like base are used in cooking.
Cultivation
Fennel is hardy, drought tolerant, and grows best in temperate conditions, but its behaviour differs by variety and climate. Garden sources note that common fennel and bronze fennel are widely available, while Florence fennel is grown for its edible bulb. In Canada, it is commonly grown in gardens and sold as a herb or vegetable, especially in warmer or sheltered locations. Because it is not reliably winter-hardy in all Canadian climates, gardeners often treat it as an annual.
