This medicinal plant is a large tree from eastern Asia. It is a very hardy tree withstanding insects, drought, and wind damage; some individuals in China are thought to be in excess of 2500 years old. The trunk has brown bark and can be buttressed, and air roots also can occur. The leaves are a unique fan-shaped form with numerous veins. In autumn, the leaves turn a vibrant yellow before falling. And yes, this is a medicinal plant used to enhance memory when the leaves are consumed. It actually is a dioecious conifer, so flowers are irrelevant. These plants are seedlings in 5-inch pots
