Foeniculum — 6 species

Foeniculum is a Mediterranean herb genus best represented by common fennel and its vegetable form Florence Fennel, with cultivars such as Zefa Fino, Romanesco, and Orion selected for their swollen, edible bulbs. All forms demand full sun — at least six to eight hours of direct light daily — and moderately moist, well-drained soil; they dislike waterlogged conditions. Drought tolerant once established, they prefer less frequent, deep watering over daily misting. The ASPCA lists fennel as non-toxic to cats, dogs, and horses, making this genus safe for pet-friendly herb gardens and kitchen windowsills.
