The only thing that is supposed to be growing in this bucket is one, single Brandywine tomato plant. I was quite surprised to find this when checking on my plants yesterday morning! I have no idea where those plants on the left came from. Some seeds must have wandered in at some point, but how and when and what are they? They look too much like a squash or melon plant for me to pull them, so I guess I'll transplant them to another part of the garden and see what happens! Any guesses on what they are?
