The largest flower on Earth is the Rafflesia arnoldii, known for its impressive size and unique characteristics. Rafflesia arnoldii can measure up to three feet in diameter and weigh up to 15 pounds. This parasitic plant is found primarily in the rainforests of Southeast Asia, particularly in Indonesia and Malaysia. It is notable for its strong and unpleasant odor, which resembles that of rotting flesh, attracting carrion flies for pollination. The flower lacks leaves, stems, and roots, deriving nutrients from its host vine. Its striking appearance and rarity make it a subject of fascination for botanists and nature enthusiasts alike.
