Hello, I was hoping someone could help me identify these plants/trees. This one I've been told is a Mullein but from what i've read about those is they take a year to flower. These have only been growing about a month. Also i've read that plant has fuzzy leaves, where these are pretty smooth. Aside from that, it does have a similar look and grows all over like a weed. These nuts from what i've read is maybe a pignut hickory tree? Up close, the leaves have very fine teeth like a saw blade. Not sure what this is. The leaves are pretty big and the bark is almost like a gum or oak tree but it's very light colored, almost white. Also are the holes shown here from insects or wood pecker? Is this a tallow tree? Thanks!
