Rafflesia Information and Photo
Search Our Inventory
Several species of Rafflesia grow in the jungles of southeast Asia, including the Philippines. Many of them are threatened or endangered. Rafflesia arnoldii is the largest; its flower attains a diameter of nearly a meter (3 ft) and can weigh up to 11 kilograms (24 lb).
It lives as a parasite on the Tetrastigma vine, as its host, which grows only in primary (undisturbed) rainforests. While many parasites appear like normal plants, Rafflesia lacks any observable leaves, stems or even roots. Likened to fungi, Rafflesia individuals grow as thread-like strands of tissue completely embedded within and in intimate contact with surrounding host cells from which nutrients and water are obtained.
