I have been trying to find out if plants in a yard are definitely sumac, which I was told they were. I have taken many photos of the plants and have tried to compare them to photos I have found searching the web, but cannot verify for sure. Is there someone or somewhere I could upload a few to have someone verify for me. I need to find out asap (unfortunately) due to this being a property I have to maintain the yard. I appreciate any help you or anyone can give me. Thanks so much.
