Found it growing in the woods on the property I built on. I have rooted a hardwood cutting and also cut a large piece out with a shovel and moved it to a full sun location where it is currently thriving. It has opposite leaves and a drooping shape to it.
I am not positive on this one, but it looks like a forsythia, perhaps Forsythia suspensa. It is a non-native shrub that has yellow flowers in the early spring before the leaves come out. The leaves usually are finely toothed on the margins, though. I don’t know what else it could be at this time.
