Rafflesia is a genus of flowering plants known for producing the largest individual flower in the world. Native to the rainforests of Southeast Asia, particularly in Indonesia, Malaysia, and Thailand, these plants are unique because they are parasitic and do not have leaves, stems, or roots. Instead, they grow on the host vines of the Tetrastigma plant. The flowers of Rafflesia can reach up to three feet in diameter and emit a strong odor resembling rotting flesh, which attracts pollinators like flies. These remarkable plants are often referred to as "corpse flowers" due to their smell and are considered endangered due to habitat loss and deforestation.
