it`s a fern that grows in a desert like a tumble-weed. it can go without water for many years. if you give it water ,the ball opens up and becomes green in a few hours, spreading a nice fern-scent. when it`s water is gone , the plant rolls up into a dry,brown ball again.
Hmmm..that is very interesting and didn't know that The wiki animation is awesome it really shows the nature of the plant Thank you Tabasco I have learned something new This is one hardy plant to survive without life-water for years ...good skill
