^Hungarian Blues are purple. It gets it's name from the color of the seeds, although you could argue it can be a blueish purple, I don't see it. The two varieties of papaver somniferum are Nigrum(dark seeds, blue) and Album(light seeds, white or yellow). Nigrums are usually grown for seeds and album are usually grown for opiates. Some strains of both are used for either one, also there's crosses. It's other species that have blue flowers, like
Meconopsis grandis. Also oriental poppies can be blue. I think I read that they're hybrids that breeder's went through a lot of trouble making.I have heard that Papaver Somniferum can rarely be blue, can't find pictures and never seen it. Maybe a hybrid? Not sure about Papaver Setigerum or hybrids of it, don't think it's blue.
If it was blue I sure hope you kept some seeds. You either got really lucky or burned.It's not uncommon for vendors to misrepresent what strain it is. Often they say it's from this region but it's not, sometimes they just sell breadseeds for a high markup. Or they grow them and it gets inadvertently crossed with other strains. It'd be nice if someone sold real solid strains. Afghanistan for example has three main strains. They're unstable but some are very hardy and some produce a lot of strong opium. I think India has like thirteen strains, maybe more. Yet I've never seen them sold, or any other one's like Turkish soft, real Iranian, Japanese, Korean, Egyptian, Iraqi, real Chinese, Laotian, Taijk, Mexican, Colombian and various strains from those regions and many others. Some may be extinct. There's also some interesting strains of Setigerum, Orientale, and Bracteatum.
There's so many possibilities. We haven't even scratched the surface compared to cannabis, where you can get just about any strain and landrace. And growing, breeding and harvesting is perfected. No lancing/harvesting tools, very rarely opium lamps(which would probably work good for hash too) rarely real opium pipes(some new ones go for as much as a good bong, real old ones cost a lot), and a lot of bad info. Everyone just wants to drink shitty tasting tea to replace H/pills. Not that there's anything wrong with that, not at all

. I just think more could be done.
Papaver Orientale does have oripavine, equipotent to morphine but more likely to cause convulsions like thebaine. It's not as bad as thebaine though. Most don't make much, some make a lot. It'd be cool if someone found out which strains are high producers. Some interesting things it can do.
Lastly, sekio was close to right, there won't be hairs on the pod itself AFAIK. On the stem is somewhat common. Also somniferums are usually much bigger than other species. Bracteatum comes close but it's a perennial with a distinct look. It's hard for the lay person or even a cop to identify it, particularly in the seedling, vegetative stage, even up to the flower stage, it looks like any other plant but if you've grown them you'd know exactly what it looks like. Not many others look like it. It's not as obvious as cannabis(which doesn't really look like any other plant) but is distinct.
