you aren't cutting those for the sap (latex known as opium) are you?
The poppy seeds most folks are familiar with in grocery stores are actually Papaver somniferum (opium poppy or bread poppy) seeds.
I think you will need to harvest and do a taste test to know for sure. But the giantium variety is indeed a species of Papaver somniferum.
You should be able to harvest a huge amount of developed seeds and they should taste just like all the commercially available poppy seeds.

No, the latex scares me. Those aren't my pictures, I actually haven't ever grown poppies before. I just was wondering about those giants from a seed productivity vs quality standpoint. Having done a bit more reading I'm not sure if these big ones are ever used culinarily. If I do try them I will do a hot water wash to eliminate any residual latex that could be on the seeds as I am not interested in a non-culinary experience. Mostly just wondering if anyone here has had any experience with these that would indicate that they aren't worth it.
Michael, if you're interested in trying them just do a google image search on gigantium poppy seeds and you should find these images, which will bring you to sellers. If any trouble drop me a PM and I'll send you a link to one.
I don't believe there would be a problem as long as you just grew them and harvested the fully developed heads for seeds.
Just call it a bread poppy (which is one of the accepted names), most of the poppies you see in flower catalogs that have the bulb are either a papaver somniferum species or very closely related and would give off a latex when young heads were cut, by the way, the latex is only useful when the sap is collected from young, developing seed pods, there is a point where the sap will no longer flow from the seed pods.
Since Papaver somniferum is the only poppy species used for baking seeds, poppy seed salad dressing, etc. One has to wonder how they sell the seeds if it is illegal to grow the plant for seeds.
