Ridolfia segetum, commonly known as False Fennel, is an annual herb that is native to the Mediterranean region, where it thrives in open fields, roadsides, and disturbed areas. It typically grows to a height of 40 to 100 centimeters (16 to 39 inches). The plant is characterized by its finely divided, feathery leaves and bright yellow flowers that bloom in summer. These flowers are arranged in small, flat-topped umbels with almost uniform rays (10-60), creating a showy display. False Fennel is notable for its strong, anise-like fragrance due to the essential oil present in its seeds and leaves.

False Fennel is valued for its aromatic properties and is used in the pickle industry for flavoring. The plant is also edible, both in its raw form and when cooked, making it a versatile culinary herb. In gardens, it can be grown as an ornamental for its attractive foliage and flowers, or as a part of a herb garden. It prefers full sun to part shade and requires medium amounts of water, with soil that provides slow to medium drainage. While it is not commonly found in cultivation, its ease of growth and maintenance, along with its culinary uses, make it an interesting choice for gardeners looking for unique herbs.CC BY-SA 4.0
