We made a new garden bed during the winter using some composted material (a windrow of piled up weeds, grass clippings, etc) and I sowed some double California poppy seeds. However I don't think any of those seeds germinated, however what came up was the typical, single orange which must've been from seeds in the compost.
This pic shows the poppies along with white anemones and a single purple Papaver somniferum,
cheers
