Mystery volunteer

We've got two volunteer plants that initially I thought were butternut squash. Their true leaves were too small, though, so I had to think about what else could have been tossed into the garden to decompose. Best guesses are cucumbers or beans.

We'll find out for sure when they start producing whatever it is they're going to produce. So far, anything that looked like it might be a flower has turned into another viney branch. Meanwhile, we keep wrapping them around tomato cages to keep them from overwhelming either the path or the onion plants, where they're growing and are too large to transplant.

Also, we bought a packet of green beans to replace the seeds that I failed to water. It was $1.22, bringing the total to $169.16.
