The plants in question are outlined in orange.
We just moved into a small town in Maine, US. I had brought a large variety of vegetable seeds with me, and decided to try and grow some radishes since we get a lot more sunlight here than anywhere else we've lived.
The previous owners left behind some packages of potting soil, which is good because layers of ice and snow made it impossible to reach dirt. The package I used was opened, and when I was preparing my planter there were some objects in it that seemed like seeds, but I don't really know.
I planted a good amount of radishes, and then later a white onion that had sprouted in our pantry. It isn't pictured, as it is off to the side. And they're all growing well and good, but these mystery plants popped up, too!
There are two of them. They started off growing two rounded leaves, then grew more pointed leaves in paired groups of two. Their stems above the rounded leaves are slightly fuzzy, but below is smooth.
Anyone know what these are? I'm happy to have new additions to the family but I just don't know where they would've come from. They look nothing like the radishes.
