The Dinosaur plant
The Dinosaur plant is one of the longest living plant in the world. Hence the word dinosaur! This plant is shaped as a small ball, which is the sleeping state. Adding some water to the plant helps the plant open. It takes about one whole day for the plant to open. In case the plant drys up it will curl back in its sleeping state for up to 50 years. The dinosaur plant is ancient and is also known as jericho rose!
