Rafflesia arnoldi is a large flower from Indonesian rainforests. It has the largest single bloom of all the large flowers. Its flower can be up to 3 feet in diameter! Some of them weight more than 24 pounds.

Rafflesia, looking strange and amazing, is a parasite. Its life depends comletely upon the host; the majority of the plant’s tissues exist as thread-like strands entirely within the host’s cells. Sometimes it takes Rafflesia up to 10 months to open its bloom. There are 17 known species of Rafflesia, most of them differ in the morphology of the flowers. Usually five leathery petals of Rafflesia are orange and mottled with light spots. In the center of the flower there is a deep well.

Rafflesia is well-known for its awful scent. There is no need to describe the smell if you know Rafflesia's nickname: "a corpse flower".
