Fennel herb (Foeniculum vulgare) is a graceful and aromatic perennial that brings both flavour and beauty to the garden. It is native to the Mediterranean region, where it has been grown since ancient times for its distinctive aniseed flavour, feathery foliage, and medicinal qualities.

Every part of the fennel plant is edible — the leaves, stems, seeds, and bulb — and each has its own flavour and use. Fennel is rich in vitamin C, potassium, manganese, fibre, and antioxidants such as anethole, which is responsible for its sweet liquorice scent. It supports digestion, helps reduce bloating, and is known for its calming effects on the stomach.

Fennel is an incredibly versatile herb. The fine, feathery leaves are delicious chopped fresh into salads, seafood dishes, soups, or sauces. The seeds are widely used in breads, teas, and spice blends, while the bulbous base of the Florence type is a favourite roasted or grilled. Herbal teas made from fennel seeds are soothing and mildly sweet. The plant is also valued for attracting pollinators and beneficial insects such as hoverflies and bees.

Fennel grows as a tall, upright plant with fine, feathery foliage and yellow umbrella-like flowers. It can reach up to 1.5–2 metres in height in good soil. It thrives in full sun and well-drained soil and is tolerant of dry conditions once established. It is best grown away from dill and coriander, as they can cross-pollinate and affect seed flavour.

How to Grow From Seed:

Sow fennel seeds directly into the garden in spring or autumn, as it dislikes being transplanted.

Plant seeds about 0.5–1 cm deep in rich, well-drained soil and keep moist until germination, which usually takes 7–14 days.

Thin seedlings to 25–30 cm apart once they are large enough to handle.

Fennel prefers full sun and regular watering, especially during dry spells.

Harvest young leaves for fresh use and allow some flower heads to mature for seed collection.

Cut back after flowering to promote regrowth and extend the plant’s life.
