Rafflesia arnoldii

The flower with the world's largest bloom is the Rafflesia arnoldii, also known as the stinking corpse lily!. This rare flower is found in the rain forests 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 jungle vine host plant to obtain water and nutrients. When in bloom, the Rafflesia emits a repulsive odour, similar to that of rotting meat. This odour attracts insects that pollinate the plant. 

Titan arum

Another enormous flower found in Indonesia is the Amorphophallus titanum, or Titan arum. It is also known as the "corpse flower" for its unpleasant odour. Like the Rafflesia, the Titan emits the smell of rotting flesh to attract pollinators. Technically, the Titan arum is not a single flower. It is a cluster of many tiny flowers, called an inflorescence. The Titan arum has the largest unbranched inflorescence of all flowering plants. The plant can reach heights of 7 to 12 feet and weigh as much as 170 pounds!
