Good luck finding a vase big enough for this flower! The bloom of the rafflesia (ruh-FLEE-zhuh) plant is about four times the size of a basketball. It grows in the rainforests of Indonesia, a country in Asia. Its size isn’t the only strange thing about it. It’s also really stinky! Some people say it smells like rotting meat. At almost four feet across, it’s the largest flower ever measured.
