Friends, I am sending 2 leaf photos in hopes of someone will know what I have. It came up last year and died back and now it is here agin and thriving, No sign of flowers. As far as I know, it just arrived in our yard, I did not plant it there. Peace, Leeta
Resembles a honeysuckle, Lonicera. There are a few invasive species of Lonicera in Indiana - possibly Lonicera tatarica? The leaves aren't as pointed at the apex on your photos, though.
