OH NO!!!!

I have just realized to my horror that a window box of what I assumed were anemones taking their time to bloom, is instead full of some unidentified and I fear unwanted invader. I am freaked out!!! Two gardening freak outs in a row. I am posting pictures of my anemones from last year to make myself feel better.
