Have you ever put out seeds and forgotten you ever did it? That must have happened here. I thought I put out Ladybird Poppies saved from a visit to The Getty over a year ago, maybe. But these are Oriental Poppies(similar but with no black dots) and they came up in another couple of places. They looked like weeds at first but were in a patch that I haven't got to weed yet and....so they flowered. Pretty.
