This is Yushania boliana, a clumping bamboo that grows to 24 feet max with 2 inch culms and has a really nice blue coloring. According the the American Bamboo Society 2009 Source List, this comes from Sichuan, China via the Fuji Bamboo Garden in Japan. From my understanding this is one of the varieties that has ties to bamboo pioneer, Gerald Bol. Yushania boliana needs afternoon shade in the Sacramento area. We have one of these in stock right now and more coming in the Spring.
