Largest Flower in the World's

Largest Flower in the World's

The flower with the world's largest bloom is the Rafflesia arnoldii. This rare flower is found in the rainforests of Indonesia. It can grow to be 3 feet across and weigh up to 15 pounds! It is a parasitic plant, with no visible leaves, roots, or stem. It attaches itself to a host plant to obtain water and nutrients. When in bloom, the Rafflesia emits a repulsive odor, similar to that of rotting meat. This odor attracts insects that pollinate the plant. 

Rafflesia arnoldii is a member of the genus Rafflesia. It is noted for producing the largest individual flower on earth. It has a very strong and horrible odor of decaying flesh, earning it the nickname "corpse flower". It is endemic to the rainforests of Borneo and Sumatra.Although there are some plants with larger flowering organs like the titan arum (Amorphophallus titanum) and talipot palm (Corypha umbraculifera), those are technically clusters of many flowers. 

Rafflesia arnoldii is one of the three national flowers in Indonesia, the other two being the white jasmine and moon orchid.It was officially recognized as a national "rare flower" in Presidential Decree No. 4 in 1993.

Rafflesia arnoldii is rare and fairly hard to locate. It is especially difficult to locate the flower in forests as the buds take many months to develop and the flower lasts for just a few days. The flowers are unisexual and thus proximity of male and female flowers is vital for successful pollination. These factors make successful pollination a rare event. 

Life cycle by M. Singh When Rafflesia is ready to reproduce, a tiny bud forms outside the root or stem of its host and develops over a period of a year. The cabbage like head that develops, eventually opens to reveal the flower. The stigma or stamen are attached to a spiked disk inside the flower. A foul smell of rotting meat attracts flies and beetles to pollinate. To pollinate successfully, the flies and/or beetles must visit both the male and female plants, in that order. The fruit produced are round lots filled with smooth flesh including many thousands of hard coated seeds that are eaten and spread by Treeshrews.
