The Giant Fennel is a drought-tolerant herbaeous perennial growing as tall as 4.5 meters (15 feet). As a plant sacred to the ancient Greek Fire gods — Prometheus and Hephaestus — the Giant Fennel is a vessel of Fire, culture, and craft. When used by Dionysos and his retinue in the form of the sacred thyrsus, the Giant Fennel also becomes a rod or sacred axis for channeling divine revelation.
