When I was little my sister and I, and everyone we hung around with, believed that common sumac (the kind with the big red conelike flowers) was something horribly deadly called "Poison Sycamoe." If you touched it, you would die. Imagine my surprise when I read in a nature book that you could brew the red flowers into a lemony flavored tea!
