Rafflesia flower has a small life of 5-7 days. Rafflesia, a native of rainforests of Sumatra and Borneo in the Indonesian Archipelago, is the largest flower in the world. Interestingly, Rafflesia is a parasitic plant without any leaves, stems and roots (It has only nutrient-absorbing threads to absorb nutrients from the host on which it lives) but for the largest flower.
It is believed that this plant has one of the most unpleasant smell in the world, because its flower has a smell of rotten meat.
