Foeniculum vulgare
Fennel, sweet fennel, sweet anise, finocchio: one plant, three harvests. Its bulb is cooked like a vegetable, its feathery foliage can replace dill, and its anise-flavored seeds are used as a condiment. It is an umbellifer, related to carrots and parsley—hence its large yellow umbels, which are a delight for pollinators.
Characteristics:
-
Triple use: bulb, foliage, and seeds—every part can be eaten.
-
Anise flavor: mild and fresh, both raw and cooked.
-
Highly ornamental: its feathery foliage and yellow umbels have a place in flower beds.
-
Self-seeding: once established, it returns year after year.
Sowing advice:
-
Exposure: full sun.
-
Soil: deep, loose, moist, and well-drained, enriched with compost. Soil that stays moist is essential: drought causes it to go to seed before it has formed its bulb.
-
Method: sow outdoors from April in the southern half of the country and in May in the northern half, 1 cm deep, directly in place—it does not tolerate transplanting well. To get an earlier start, sow in a heated greenhouse from February–March. See how to sow your seeds.
Care advice:
- Thin to 25 cm apart. Water regularly and evenly, and mulch generously.
-
The game-changing step: mound soil around the bulb when it reaches the size of an egg. It will grow larger and remain white and tender instead of turning green and tough.
Harvesting advice:
- Harvest the bulb when it reaches the size of a fist, cutting it at ground level. The base left in the soil often produces small, tender shoots.
- Pick the foliage as needed. For the seeds, cut the umbels when they turn brown.
Beneficial companion planting:
- Be aware that fennel is known to inhibit the growth of many neighboring plants—especially tomatoes, beans, and cabbages. Plant it separately, along the edge of the vegetable garden or in a flower bed. See companion planting in the vegetable garden.
Benefits for biodiversity:
- Its large yellow umbels are among the most visited flowers in the garden: bees, hoverflies, and beneficial parasitoid wasps flock to them all summer long.
- It is a major host plant for swallowtail caterpillars—if you find them on your fennel, leave them be; the butterfly is worth it.
Uses:
- Bulb raw and finely sliced in salads, braised, roasted, or baked in a gratin; chopped foliage over fish; seeds in infusions, breads, or marinades. See our traditional plants to sow.
Harvesting your own seeds:
Let one plant flower: that is the harvest itself. Cut the umbels when the seeds turn brown and dry them upside down. Be aware that it can cross with wild fennel, which is widespread in the south of France. See how to store your seeds.
Commitment to Quality: at SemiSauvage - Permaculture, we grow and select our seeds with respect for living things as our guiding principle. Based near the Auvergne volcanoes, we choose open-pollinated, non-hybrid varieties, test them for germination rates, and carefully sort and package them without any chemical treatment. Our belief: to give gardeners back the ability to resow, year after year, seeds that truly belong to them.
One plant, three harvests, and a pollinator magnet.
