Gardeners' Notes:

Neutral grrrlgeek On Sep 26, 2009, grrrlgeek from Grayslake, IL (Zone 5a) wrote:

There seems to be some confusion between this, the cultivar group Foeniculum vulgare var. azoricum or Florence Fennel/Finnochio, and common fennel. The azoricums forms a bulbous leaf base that is eaten as a vegetable, while the common fennel, including bronze fennel, does not. Vegetable fennel is a biennial, harvested at the end of it's first year. Herb fennel is generally perennial to zone 4. Please take that into consideration when reading/leaving comments.

I will update next year after I grow some myself. Yummy :)

Fennel is an annual in my zone 3 Alaskan climate, but I start it from seed every year. The bulbing types seldom reach much size, but I find the leaves to work well as a dried herb. As an ornamental, it adds another texture to the flower garden.
