Is this a pineapple tomatillo seedling? I could not get the seeds to sprout in containers so I scattered them in one bed outside. Unfortunately, my soil was contaminated with pesky plant seeds too so I need to cultivate. Before I do that, I need to know what these are.

This type of seedling has only grown in the bed where I scattered some seeds, even though both beds I have used the same contaminated mix. I just want to make sure.
