Joe, i make cane yelpers. The cane most people refer to is native river cane. There are a couple of different kinds, the main difference is in how big it gets. the small cane is tecta, the big river cane ic called giganta.Both of these river canes are native to the U.S. They normally grow in wet areas along creeks and rivers, thus the name river cane. The bamboo that most refer to is not native to the U.S.and is from China,called Chinese bamboo and will grow almost any where. Some people use both kinds in a call, i use only native river cane, not saying that it is better, just that i prefer river cane. Hope this helps. Larry
