Discover how to grow fennel from seeds, harvest its aromatic seeds, and understand the difference between common fennel and Florence fennel.
Sow fennel seeds about 1/4 inch deep in fertile, well-drained soil in a location receiving full sunlight. Keep the soil evenly moist until germination, which commonly occurs within 7–14 days under suitable conditions. Thin the seedlings as they grow to provide adequate space for mature plants.
Allow fennel plants to flower and develop seed heads. Harvest the seed heads when the seeds turn greenish-brown and begin to mature, before they scatter naturally. Cut the heads carefully, place them in a paper bag, and allow them to dry in a well-ventilated area. Separate the dry seeds and store them in an airtight container in a cool, dry place.
Common fennel is primarily grown for its aromatic leaves and seeds. Florence fennel is a cultivated type selected for its enlarged, bulb-like leaf bases, which are used as a vegetable. Both belong to Foeniculum vulgare, but seed varieties differ in their growth characteristics and intended culinary use. Check the variety description before planting if you want to harvest fennel bulbs.
