None of the things in the pot look like Pyracantha. I'm not familiar with how they look as seedlings, but I'm pretty sure those are not it. They look more like Portulaca or some kind of Sedum (like Angelina). Where was the pot? If it was underneath a hanging basket with those plants in, there's your culprit.

The pot was on the deck by: Bruce
Hi. The pot was just sitting on the deck and I put the seeds in it. I don't know what these are but I didn't think they were pyracantha either.
