Glad you told me what this was. Looks like a candy tree. It's very interesting. The colors are bold and vibrant and the dots on the drupes are curious. I'm going to have to look at a sumac more closely next time I see one.
I was shocked when I shot sumac berries last year. I used to think the berry cluster was just brown fuzzy stuff...but when you take a close up, you realize they are juicy berries... I read that they used to make jelly with the berries.
