Hi, just joined. Walking along the river banks here in St. Cloud, MN and this plant is everywhere. I've seen some that are quite tall (12-18 ft high). It's mid-winter here. I thought it was highbush cranberry or nannyberry but that doesn't quite seem to fit it. It has up to 3 oval shaped seeds in each berry. (apologize for actual tree pics I only had cell phone with at the time) Thanks, Ryan.
