The rafflesia is the most enormous flower in the world. Its bright red bloom can be three feet wide! It takes two years to develop and stays open for a week. Unlike other plants it has no long stem or green leafs. It happily grows on the roots of other plants. You won’t want to get too close to this gigantic blossom; it stinks! some people say it has a foul odour, like that of rotten meat. Because of its nose-pinching stench, it is also known as the “corpse flower” or “stinking lily.” Luckily it is not found in North America.
