I'd just sow where you want them to grow.Maybe they will, maybe they won't. Meconopsis are supposed to grow well in our area and I've seen beautiful plants in the nurseries and 'farmer's markets' but have never been able to grow them from seed, much less overwinter them, so I just quit and went to other varieties. Some battles are just not worth winning. Be sure to keep us up to date with your success.
Thanks for the support. And here's the deal - I have been a proponent of the Papaver somniferum poppy. It has a little to do with my profession.
Anyway, that is the Genus/species that I am interested in growing.
What I may do is get some seeds, from like eight million cultivars (he he) and plant one set in an indoor terrarium, one set in pots outside, and one in the beds. I will dance to the poppy faries on a routine basis during these seasons, and sacrifice a bunny in the interim (note: sacrificing a chicken will not equate to the suffering I have endured, but the rabbit will certainly make me feel like I have obtained a small amount of revenge).
