You are in for a real treat with this gourmet, but often overlooked, garden wonder. Also called Roman or Florence fennel, the crisp, bulbous stem has a delicious, anise flavor and can be eaten raw, sautéed, fried, and used in soups or pasta. Feathery foliage is attractive and is an excellent fresh garnish. Seed can also be harvested as a spice. For best "bulb" production, sow for fall harvest.

Family: Apiaceae

Native: Africa, Asia, and Europe

Hardiness: Perennial in USDA zones 4–9; grown as an annual.

Variety Information: The crunchy, dense, licorice-flavored "bulb" is comprised of tightly layered, overlapping, swollen stalk ends. The feathery foliage looks similar to dill, but has a delicate, anise flavor. The seeds also taste similar to anise or licorice. 'Romanesco' is a florence type fennel.

Exposure: Full sun

When to Sow Outside: "For "bulb": Midsummer for fall harvest is optimal; ideal soil temperature is 60°–75°F. In cool summer areas (under 75°F): 1 to 2 weeks after average last frost. Mild Climates: Sow in fall for cool season harvest. For foliage only: Every 3 weeks after average last frost until midsummer.

When to Start Inside: 4 to 6 weeks before average last frost (recommended for spring "bulb" production). Use biodegradable pots for transplant.

Days to Emerge: 7–14 days

Seed Depth: ¼"

Seed Spacing: A group of 3 seeds every 10"

Row Spacing: 10"

Thinning: When 1" tall, thin to 1 every 10"

Harvesting: BULBOUS STEM BASE: Harvest any time after the base begins to fatten, and before plant begins to bolt. Cut just below the soil surface. LEAVES: Can be clipped for fresh use almost any time after plant becomes established. SEEDS: Harvest seeds when they turn from yellow green to grey green. If allowed to turn brown, they may fall to the ground before you can harvest them.

This is not the bulb producing variety

2 out of 5 stars Jul 22, 2020
This is false advertising as the picture and description indicate a bulb producing variety but these seeds do not. They do grow into wonderful stems but not bulbs.
Regan Anderson from WA
Owner Response: Hi Regan, We are sorry you were not satisfied with this bulb-producing fennel. Some reasons fennel may not produce a bulb are dry conditions and also warm conditions which can occur as spring and summer heat up. Fennel sown for fall harvest usually grows with ease and the cooling temperatures are perfect for bulb productions. We sure hope you will try this cultivar again. Happy gardening!

false advertising: the text and images on the packet indicate bulb fennel. The seed are not.

seeds in the packet have not produced bulb fennel. They are producing flowering stalks for fennel seed. So disappointed. Evidently I'm not the only one. please do better.

Owner Response: Hi Katherine, Thank you for taking the time to leave a review. This is a Florence/bulbing fennel cultivar however, several environmental factors like heat and drought do factor into how big the bulb gets prior to flowering. Because fennel is heat sensitive it can be easier in many climates to grow it for a fall harvest. We sure hope you will try again. Happy gardening!

Not bulb fennel

4 out of 5 stars Sep 11, 2020
Big, beautiful plants loaded with flowers. Attracts lots of pollinators. Hosted lots of swallowtail caterpillars and they still looked great. BUT none of them produced bulbs. Very disappointed.
Lorraine from MA
Owner Response: Hi Lorraine, Since fennel needs cool weather to produce a bulb, gardeners often have better luck with a fall crop where the weather is more progressively cool. We hope that helps. Happy gardening!
