I drove by these today. In river bottoms, it was the 1st shrubs to leaf out it appeared. For sure some type of shrub. Ya, it's kinda on the tip of my tongue but I think I even have to wait til they flower out and grow more. I know someone here knows but this one is tricky. I know it isn't something like mulberry as the because when I looked at mine in yard, no leaves. Some under-story shrub that's prevalent in bottoms here around me. I remember when honeysuckle was all over in SE iowa, I remember that being a much smaller plant. Maybe I'm wrong though.
