How And When Should I Plant Poppy Flore Pleno Papaver Nipifragum Seeds?

Question

I have purchased the above seeds recently and it tells me to visit their site Ferri Seeds but I can’t seem to get on the site. Can you please tells me how to grow theses seeds, and when? Should it be in the spring in a little greenhouse or can they be placed directly in the cultivated ground covered slightly with dirt. I’m confused. Can you help? Please. Thankyou.
