It seems to be a death match between the hops and 4 o'clocks. Unfortunately the hops is a sure looser unless I assist it. Only a few days ago the 4 o'clocks were winding around in the background and this morning I had to remove the strangle hold it had on the hops. I also uprooted several 4 o'clocks just to make sure they didn't try it again before I got home to implement a more permanent solution. They're still climbing the drain pipe nicely and may have to uproot most of them so that the hops can have plenty of breathing room.
There also seems to be another vine plant coming up near the far right hops plant that looks similar. It might just be another hops vine coming up with the leaves slightly different.
The hops plant on the far left still hasn't emerged and may never emerge. I did split that one off of one of the larger roots so everything I bought has sprouted and it will put off more roots next year.
