Selaginella is a perennial herb that grows in South America. It is a little fern with branches and leaves that resemble cypress trees. Because of its vitality, it has a name - “Nine Resurrection Grass”.

In such a barren natural habitat, there is simply not enough water, but Selaginella never complain nor give up efforts, in the billions of years of evolution, it slowly learned super survival skills: as long as The climate is slightly humid, even if it is just the rapid flow of water when it rains, Selaginella will desperately seize the opportunity to grow squamous leaves to absorb moisture. Not only that, there is a set of cypress
