An attractive perennial, but I got tired of pulling up seedlings. Self-sows too enthusiastically for me, and I got rid of it.

Very pretty plant, bees love it. Reseeds easily (I'm in Z7a, Long Island NY, sandy loam) -- I let them grow, lose the foliage to caterpillars on one or two a year. Have two that are a few years old and close to six feet tall. Can use the leaves, pollen, flowers, seeds for flavoring. Seeds nice to chew on while gardening. Deer never bother it. I cut it back to the ground after I've harvested seeds.

I planted a few bunches of small bronze fennel in our Vermont mountain (1,800 ft. elevation) garden early last year and it survived the winter and doubled in height and vigor this year. Very attractive upright growth and lovely flavor of anise. Aside from fresh garden salads I haven't found a good use for it and would welcome new ideas.

I don't prefer Fennel as a seed, but love this plant. The foliage is a feathery, brownish-copper in color [when it emerges in the spring] and it heavily reseeds, so if you don't want them popping up all over your beds, do dead-head them. I've heard Swallowtail Cats are attracted to them and i did see ONE last summer. The plant in this image, I planted last year, and it's now close to 4feet tall, if not higher. Pretty, "Queen Ann's Lace" type blooms, though these are yellow. The plant dies back at the end of the year, possibly Bi-Annual, or short lived Perennial.

Easily winter sown.

My mum surprised us at Christmas with tiny bottles of what she called fairy dust, the flowers of fennel. Heavenly scent we use for cooking, and we had to have more! Fennel is grown all over the yard now.

Striking, bronze-purple foliage. It is a vigorous grower, and its color can be used very effectively in the border. Also known as Copper Fennel. It has the same licorice-anise flavor as Florence Fennel, and may be used in the same ways. It tends to reseed when well situated.

I garden in the Mid-Atlantic and it is perennial here in zones 6/7. This is a wonderful plant. It hosts a variety of caterpillars ever year and it's blooms provide nectar for butterflies. The seeds are good in baked goods, especially desserts and tea. They are also useful medicinally especially for stomach upsets and gas. Good natural breath fresheners. The leaves are outstanding, feathery and although bronzey with age, I find mine are often a blue/green/grey color. Yellow umbellic flowers perfectly compliment the foliage. It is a wonderful addition to the herb OR perennial garden! The leaves are useful in cooking, especially braised and served in soups and fish dishes. They are also useful cosmetically. Easy to grow and very easy to grow from seed, in fact you'll usually notice a few ... read more

Bronze fennel does not winter over in my USDA zone 3 climate, but we grow it as an annual. I mostly grow it as an ornamental, but have dried the fronds of leaves, as well.

Mine was more bronze last year but is now partly shaded by a red twig dogwood and a buddleia, and so more green. Easy to grow, and survives well in my zone 6b.
