I'm embarrassed to say, but I was looking at the 8 deer I spooked up, and didn't think about leaves, until after I had left. I'll have to run by again and see if there are any identifiable.
Dondiego;
I actually did test some a few years ago, and it was okay but it was dirty. I had the same results with Wisteria and Castor Bean plants. Castor Bean looks like it would be fantastic, but the test I made was exceptionally dirty.
Edit; there a few different Sumac's and the one I tested we call Poison Sumac. Not sure that is the proper name, but the seeds are supposed to be poison and they dry red. The leaves are also streaked with red.
