I have a lifelong love and longing for poppies, mostly thwarted. The big showy Oriental perennial poppies loathe and despise being transplanted, so I never had any luck with them after $$$ wasted. Even though they exist in abandoned farmsteads all over Iowa, but NO orange poppies for me! :(
I have tried some of the annual types, Icelandic and Shirley, and had mild success.
Lately I have been having better success with the old annual paeoniflorum in Zone 6. I get fresh seeds each year from a community garden plot. I was building up a nice little groups of self seeding ones when we moved, so I will be starting over. These are,
I believe, illegal to grow. But I do not care.
Two times in my life I saw the elusive blue Himalayan poppy, both times in Scotland. Once it was in the garden of our auntie who had a perfect cottage by the sea. That poppy is a stunner.
