Some of the foliage made me wonder about hackberry too, but if it's all one thing, then there are basal leaves that look different, vs. the leaves that look like they are higher on stems. Yes, cutting a baby @ soil level could result in a "poof" of foliage that looks like a shrub, but I'm not leaning toward hackberry as an ID for this if it seems like all 1 plant. But not saying it's definitely not because I'm only familiar with the one species in our yard.
Hope you get some sunshine, Nancy! : )
