What kind of poppies are associated with veterans? Y'know, "In Flanders fields the poppies blow Between the crosses, row on row," I see them (I think) growing along the roadside here, and I'd love some for my garden, but what kind are they, and where can I get them? eta: Thanks, all, for the quick responses!
