Fennel grooved. Fennel is widely cultivated, both in its native range and elsewhere, for its edible, strongly flavored leaves and fruits. Its aniseed flavor comes from anethole, an aromatic compound also found in anise and star anise, and its taste and aroma are similar to theirs, though usually not as strong. Florence fennel ("Foeniculum vulgare" Azoricum Group; syn. "F. vulgare" var. "azoricum") is a cultivar group with inflated leaf bases which form a bulb-like structure. It is of cultivated origin, and has a mild anise-like flavor, but is sweeter and more aromatic. Florence fennel plants are smaller than the wild type.
Fennel ("Ferula communis") is a large, coarse plant, with a pungent aroma, which grows wild in the Mediterranean region and is only occasionally grown in gardens elsewhere. Other species of the genus "Ferula" are also commonly called giant fennel, but they are not culinary herbs. In North America, fennel may be found growing in the same habitat and alongside natives osha ("Ligusticum porteri") and "Lomatium" species, useful medicinal relatives in the parsley family. Most "Lomatium" species have yellow flowers like fennel, but some are white flowered and resemble poison hemlock. "Lomatium" is an important historical food plant of Native Americans known
