The “Rafflesia arnoldii” is the largest flower in the world. The flower is named after Sir Stamford Raffles and Dr. Joseph Arnold who first discovered the plant in May 1818. It was known as the “corpse flower” because of its strong odor similar to rotting flesh. It weighs up to 24 pounds and around 3 feet wide. Once the flower blooms, it will only last for five to seven days.
