The world's largest flower is the Rafflesia arnoldii, also known as the corpse flower. Native to the rainforests of Sumatra and Borneo in Southeast Asia, it can grow up to three feet in diameter and weigh up to 15 pounds. One of its most distinctive characteristics is its foul odor, reminiscent of rotting flesh, which it emits to attract pollinators such as carrion flies. Despite its unappealing scent, the Rafflesia is a fascinating example of nature's diversity and complexity, drawing interest from botanists and tourists alike.
