The Equisetum Caeruleum is an extremely common, tiny plant and can be found virtually anywhere. It blooms in early autumn. It has thick, oval leaves, which are usually dark red. It also grows decent sized flowers, which can be dark yellow, orange, dark silver, white and dark red. These plants grow within short distances from each other, but it's no trouble to control and maintain their growth. They can be used to create a poison. As a defense mechanism the Equisetum Caeruleum grows small thorns. They rely on water currents to carry their seeds away to reproduce. Once pollinated, they grow fairly large, inedible fruits.
