Also called "finocchio," Florence Fennel is both an herb and a vegetable, since the bulbs are edible in fall. Like all fennels, this one is highly aromatic and flavorful.

Plant Information

Fennel is a bulb-rooted herb with handsome yellow flowers, similar in appearance to dill bloom. By the end of the growing season, you'll have fully-developed bulbs which can be harvested and cooked as a vegetable.

When and Where to Plant: Plant in early spring or in late June-July so that the plants can mature in cooler fall weather. Spring-sown plants are more likely to bolt so many gardeners will wait until July to seed their fennel and harvest the bulbs in the fall. Fennel seeds should be planted in full sun in a well drained soil. Plant directly into rich soil and keep moist until the first leaves appear. Then keep on the dry side.
Care: When the bulbs are about the size of an egg, pile the soil up around it so it will continue to grow away from the light. You may want to cut off the seed heads when they form to give the bulb more time to grow before harvesting.
Harvesting: 14-16 weeks after sowing. Pull the plants when the base is at least 3" or more in diameter. Make sure to hold onto the bulb as you pull. Cut off all but the top 9" of the fern growth.

Q & A

Plant With These:

USDA Hardiness Planting Zones

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
