Fennel seeds

The sweet licorice herb worth a spot in your garden

Fennel (Foeniculum vulgare) is a tall, elegant herb grown for its warm, sweet, anise-like flavor. Its feathery blue-green fronds, golden flower umbels, and ribbed seed all carry that unmistakable licorice note, and every part is useful in the kitchen. Whether grown as an aromatic herb for its fronds and seed or for the swollen bulbs of Florence types, fennel is a striking, architectural plant that bees, butterflies, and swallowtail caterpillars find irresistible.

How to grow fennel from seed

Fennel is easy to start from seed. Sow fennel seeds about a quarter inch deep in a sunny, well-drained bed once the soil has warmed, then thin the seedlings to stand roughly 10 to 12 inches apart. Herb fennel grows 4 to 6 feet tall and produces fronds within weeks, with seed ripening later in the season. Fennel forms a taproot and dislikes transplanting, so it does best direct-sown where it will grow. For the full step-by-step, see our complete guide to growing fennel from seed.

How to use fennel

Fennel is generous in the kitchen. Snip the feathery fronds over fish, salads, and roasted vegetables, or use the golden pollen as a delicate seasoning. The ripe seed is a classic spice for sausages, breads, sauces, and spice blends, and is traditionally brewed into a warm, soothing herbal tea. If you grow Florence-type fennel, the crisp, anise-flavored bulb can be sliced raw into salads or roasted until sweet and tender.

Fennel and its licorice-scented cousins

If you love fennel, you will enjoy its aromatic relatives. Try anise for the same sweet licorice note in a compact annual, dill for bright, feathery greens in the same family, or caraway for a nuttier, earthier seed. Explore the full range in our herb seeds collection.
