From bulb to stalk to frond, here's how to grow, select, and cook with fennel, the sweet anise-flavored veggie that deserves a spot on your plate.

You've probably spotted fennel at your local farmers' market during chillier months—but what exactly is this bulbous, feathery plant? Native to the Mediterranean region, fennel is one of Italy's most popular vegetables. Most fennel available in American markets is grown in California. The type you'll find—Florence fennel (sometimes labeled "fresh anise")—has a bulb-like base, stalks like celery, and feathery leaves that resemble Queen Anne's lace.

Like celery, the entire fennel plant is edible and lends itself to a wide variety of cooking applications. In fact, this mildly licorice-flavored plant is a member of the parsley family. Lastly, we can't ignore the health benefits of fennel. Just one cup of fennel contains almost 20 percent of your recommended daily value of vitamin C. You'll also find plenty of iron, fiber, and potassium. Here's everything you need to know about fennel, plus plenty of delicious and easy fennel recipes

How to Grow Fennel

Peak growing season for fennel is fall and winter. However, home gardeners can also slip in a quick planting in spring for an early summer harvest. When planting, look for compact bulbs that are relatively heavy and firm. Avoid those that are splitting or browning, or have other injuries.

Fennel enjoys cool weather—not hot, but not freezing. Although it’s easy to germinate from seeds sown directly into the garden after the soil has warmed, transplants are helpful to get a head start in spring or in raising a fall crop that must be started in the heat of summer. It takes about three months for fennel to produce the bulb, so do the math to determine when you need to start and if you have enough time before the weather turns hot or starts freezing.

RELATED: Plan Your Vegetable Garden

Plant fennel seeds or transplants in a sunny, well-drained bed that has been amended with compost. Thin seedlings to stand about 12 inches apart. Keep the bed moist, and be sure to feed your fennel every two to three weeks with a liquid fertilizer. After the bulb grows to about 2 inches in length, cover it with soil or mulch, which will make it tender. Snip off any flower stalks that may form to prevent the bulb from splitting. When it’s time to harvest, use clippers to snip under the bulb and cut the taproot.

Try planting fennel varieties such as Zefa Fino or Trieste—they resist the urge to flower, channeling their energy into the bulb instead.

How to Buy Fennel

If you aren't growing your own, fennel is widely available at most grocery stores year-round or at farmers market when in season. Look for small, heavy, white bulbs that are firm and free of cracks, browning, or moist areas. The stalks should be crisp, with feathery, bright-green fronds. Wrapped in plastic, fennel keeps for just a few days in the vegetable bin of your refrigerator; the flavor fades as it dries out.

How to Cook Fennel

All parts of the fennel plant—bulb, stalk, and the feathery fronds—are edible, and will add texture and flavor to salads, slaws, pastas, and more. Thinly sliced raw fennel bulb adds a sweet licorice flavor and crunchy texture to salads. To slice the bulb, stand it on the root end and cut vertically with a sharp knife of mandolin. To soften the flavor of the bulb, try braising, sautéing, roasting, or grilling it.  

Fennel stalks can take the place of celery in soups and stews, and can be used as a "bed" for roasted chicken and meats. Use fennel fronds as a garnish, or chop them and use as you would other herbs, like dill or parsley. Oh, and one last thing—fennel and seafood go together like peas in a pod.
