Arrowwood Viburnum is growing in most patches of woods in central NC that I've been in. It's scattered in the mountains. It grows a lot around the edges of woods. I may be able to get you a few if I'm out around some in the near future. It makes good arrows, and it's easy to grow, also. Here in the mountains and foothills, there is witherod viburnum (V. cassinoides) growing in almost every swampy, boggy place in the woods. It also makes great arrows. Black Haw viburnum and maple leaf viburnum are common throughout the state, and make good arrows if you can find a piece straight enough.
