Rafflesia: The Flower That Disappears Inside Another Plan

Rafflesia can produce one of the most astonishing flowers on Earth—yet for most of its life, there is almost no plant to see. It survives as reduced tissue hidden inside a living Tetrastigma vine, then briefly erupts into the forest as a flower. This film follows Indonesian conservationist Septian “Deki” Andriki’s thirteen-year search for Rafflesia hasseltii and explores the biology behind its hidden life: extreme parasitism, host dependence, carrion-fly pollination, the mystery of seed establishment, and why protecting the flower means protecting an entire network of vines, rainforest and local knowledge.
