Good find. Those used to be quite common around where I live. They were brought in primarily for hedgerows, as they were through out most farming regions. Only a few left around here, and they are now considered an invasive species. Very hard wood. Being "invasive," they can grow fast when there is enough rain. So usually not quite as dense as tropical hard woods, but one of the few trees in No. Am. that can compete. Beautiful color. I have a few sticks I bought from a vendor who was clearing them in southern Illinois. Long pieces such are used for bow staves are worth $$.
