Rainbowbamboo is a fast propogating plant which is named after its rainbow colored flowers. Its complete life cycle is fairly fast, making rainbowbamboo a good source of seeds. Each plant will produce six nuts at a time, and many flower petals. The flower petals are classified as a leaf, and have medicinal properties if your creatures eat them.
