The fastest growing plant on the planet is the Dinosaur Plant, also known as the Resurrection Plant. When you place these ancient plants in a bowl of water, they use their unique vascular root structure to quickly intake the water. They will open up and turn green in hours!Let them drink all the water, dry out and they will eventually return to a dormant state. You can let them hibernate for up to 50 years and they will still spring back to life in hours when placed in water!
