Good to know! These plants didn't seem to be taken care of as well as they should have been when I got them. This poor thing was getting pretty dry. Thank you so much for your help! :)

double pane insulated window??? cold at night.. might be making a natural curl.. worse ... regardless.. that is some great lush vigorous growth.. so it cant be getting too cold at night ... let me put it this way.. if there was anything wrong.. it wouldnt be growing that vigorously ... eh?? if it is sprouting roots in mid air... i will guess you could cut the above off.. root it.. give it to a friend [hence the name] .. and yours will rebud below the cut.. anyone want to confirm or destroy that guess??? ken

Thank you all for the responses. It looks like Wild Radish has hair on the early leaves while Mustards do not. I don't recall hair on any leaves so Mustard it is (I think) : )

The closest big city from me is 250 miles away. I live in a rural area by a big lake in Northeast Montana. Actually, we were named the Middle of Nowhere because we are the furthest from any big city. Thank you all for your help!!!
