Black Dragon
About this plant
Dragon arum is known for its striking dark purple to black spathe and a tall spadix that emits a strong, unpleasant smell to attract pollinators. It has large, arrow-shaped leaves and is often grown as an ornamental plant for its unusual flowers. The smell is similar to rotting meat, which helps attract flies for pollination.
