distribution_en:

description_en: Genus of 170 species of robust, tap-rooted, usually hairless, aromatic, herbaceous perennials found in rough, grassy places, dry slopes, and gravelly roadsides from the Mediterranean to C. Asia. They bear branching or simple stems, with 2- to 5-pinnate, usually basal, light green leaves, to 80cm (32in) long, the ultimate segments linear to obovate. Usually forming a mound of finely divided leaves, they are effective foliage plants when mature. Giant fennels (which should not be confused with the edible fennels, Foeniculum) bear white, greenish white, yellow, or purple flowers in terminal, lateral, compound umbels, to 15cm (6in) across, although they may take several years to flower and often die after seeding. Grow at the back of a border, or as a specimen plant in a sunny, open site in a wild garden.

hardiness_en: Hardy to -10°C (14°F).
