There is more than one type of Sumac. One is poisonious and must be avoided. I do not know where it grows.
The non poisonious one has been used in the far Northern Americas to make unique furniture. The grain of the wood is telling to the educated eye and the pronouncement of the word is quite unique as well.
In the southern United States, children use the brownish/red buds as imitation coffee when playing house. That's all I know about wild sumac. It's beautiful in the fall season in the states. NJoy
