Jo Ann, the poppies and larkspur can actually be sown earlier in the fall. Then they can sprout and winter over as tiny seedlings. They're not bothered by winter weather at all. They're very cold hardy.
This pic shows my larkspur last January. What appears to be a groundcover over the bed are all larkspur. I had to stop growing them because of invasive reseeding.
I shouldn't have allowed so many to stay the year before.
