Description

Fennel (Foeniculum vulgare) is cultivated for its aromatic, anise‑flavored seeds and delicate foliage rather than its bulb. The tall, yellow‑flowering perennial produces seeds used in tea and bread, and it serves as a valuable forage plant for bees and hoverflies.

Care instructions

Plant fennel in a sunny, warm spot with deep, nutrient‑rich soil, as it develops a deep root system. Keep it away from tomatoes and beans, which it does not tolerate well. Harvest the seed heads in August and September when they turn gray‑brown, and dry them in a well‑ventilated area.
