I've heard they're difficult.

I've seen the plants after flowering at 'The Blue Poppy' and plants before flowering at 'Surry Gardens'. Both places are within driving distance of Deer Isle. I think that they are at least possible on the coast - not sure about inland. They are hard to start - and usually die after flowering - so save the seed - and they are sooo beautiful in photos. Good luck!

I grew this ONCE! I got some seeds from someone in Canada before it was taboo. It took three years to bloom. Bloomed once and I lost it last year in the deep freeze without snow. I bought one last year and planted it, but I don't see it coming up!

Gorgeous. A thrill to see, but really difficult!

The one I purchased last IS coming up! I wonder if it will bloom!
