Annual poppies?

[Nicos]

Any advice on growing these please?
Previously I’ve sprinkled seeds and nothing seems to have some up.

I’ve treated myself to a couple of different types and read that they should be frozen for a few days. Thing is…why haven’t the previously sprinkled ones grown?
Welsh poppies and wild Flanders poppies do really well for me- just not other annual varieties.
What am I doing wrong? Any tips please?

I've had a decent success with Mother of Pearl poppies in the past by sprinkling, watering in and then covering over with a light layer of compost then watering a little bit more. I came to the conclusion I was getting terrible germination because the seeds left on the seedbed were blowing away or being eaten before they germinated.
Not sure if that was actually what happened but after I covered them up a bit I actually had some poppies!

Nicos I’ve got California poppies growing, they appeared about 10 years ago and self seed everywhere
I only really pull those out of my veg beds.
