The Equisetum Yannanensis is a scarce, large plant and can be found only on small tropical islands. It blooms twice a year, for 1 month. It has huge, circular leaves, which are usually lime green. It also grows small flowers, which can be light gold, light purple and light blue. These plants grow in tiny groups, but it's really difficult to control and maintain their growth. They can be dried and used in cooking. As a defense mechanism the Equisetum Yannanensis taste extremely sour. They rely on water currents to carry their seeds away to reproduce. Once pollinated, they grow fairly large, delicious fruits.
