Mystery Guest

While out weeding, I ran across this interesting guest. Since it looks like a vine, I decided to save it and see what grows. It would be an odd weed. As far as I recall, no plants were put there last year, about 3 yards away I had tried watermelon, but nothing fruited.  There is a lot of shade in the this area, so will be fun to see who it is.

 27 days later and tomatoes are growing nicely. A few blossoms are popping out.
