Largest Flower - Rafflesia
Rafflesia is the world's largest, the heaviest, the rarest and the one of the most stinkiest flowers in the world. It grows to 1 metre wide and weighs about 10 kgs.
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.
Rafflesia is a huge speckled five-petaled flower with a diameter up to 106 cm, and weighing up to 10 kg. Rafflesia flower has a small life of 5-7 days. Rafflesias have their stamens and pistils fused together in a central column, producing a corona, or crown, in the shape of a ring. The reddish brown colors of the petals, are sprinkled with white freckles. The smell attracts the carrion flies and then pollination occurs. After 9 months of maturation, Rafflesia plant opens into a cabbage-sized bud. The sexual organs are located beneath the rim of the disk.
