I am cleaning up some neglect in a garden, but it's not too bad. There are two of these tall guys among the tomatillos, and the way they're spaced, it seems that they were planted with purpose. I have no clue what they are. Can anyone help ID these guys? I'll be weeding over the next couple of days, and want to make sure I get them if they're weeds. They don't seem to be choking anything, but who knows.
