They need frost to break dormancy, and like to
gorw on cultivated ground. Best sown in the autumn (when poppies the
seedheads ripen naturally) for growing the next year.

Oh right, thanks. I sowed them in spring. Perhaps they will come up next
year if I dig over where I planted them.


I believe they can remain dormant for up to fifty years so you might have a
long wait!
