Thank you all so much for your continued help with this. I think what I may do is uproot one of them and scan it in.
@Leftwood . . . . I cannot believe I left off Colorado! My apologies. I have definitely fixed that.
Whatever they are, I like them so they get to stay. They are not overly aggressive and fit in well with the 'weed' grass that was planted by the birds throwing it from their feeder. :)
If it helps at all, these plants are growing primarily in the same area where the other discarded seed planted. Perhaps it grew from that?
Thank you all again so much!
