Fennel is a cool-season vegetable that grows to about 2 inches in height, with feathery, edible, dill-like foliage. This plant bears the scientific name Foeniculum vulgare. Typically, it can grow in roadsides, pastures, along the edge of wild habitats, rocky shores and hills. The base of the leaf stalks overlap and swell to form a thick, crisp, above-ground bulb with a fresh, delicate anise-like flavor. Fennel requires frequent irrigation, plants that do not receive enough water can develop cracked stems. In some cultures, fennel seeds are eaten after meals as a breath freshener. Fennel seeds offer certain health benefits, along with potential health risks. There are two basic types of fennel:
- Florence, also known as finocchio
This type of fennel (Foeniculum vulgare v. azoricum) is an annual plant commonly used as a vegetable. An alternate name for this vegetable is “bulb fennel. Florence fennel grows about 3 feet high and has a thick, bulb-like base that is similar to celery. The leaf stems of Florence fennel are an important ingredient in Italian cuisine. It can be incorporated into a stir-fry, served boiled or steamed, or added in slices of raw fennel to a salad. “Trieste” and “Zefa Fino” are two varieties of Florence fennel recommended by Washington State University Extension.
- Sweet Fennel
Sweet or common fennel, Foeniculum vulgare, is a perennial plant grown as an herb as well as for its seeds. Sweet fennel can reach a height of 4 or 5 feet. In French and Italian cooking, fennel leaf is commonly added to sauces and mayonnaise. Fennel is also an ingredient in some kinds of breads, cakes and liquors.
Bronze fennel or Foeniculum vulgare “Purpurascens” is a type of sweet fennel whose leaves have an attractive bronze cast. The plant is useful not only as an herb, but also as an ornament in the flower garden. Bronze fennel is often planted in butterfly gardens, since it attracts butterflies and other beneficial insects. In particular, bronze fennel is an important host plant for the black swallowtail butterfly.
Fennel seeds form long, thin curved seeds that vary in color from brown to light green, with the green seeds being considered the most valuable.
