In a drawer in my bedroom,(not with clothes or anything), my wife has a ton of them, she bought them in case we have to live off the land because of Zombies or something. Smoke and Pet free.
Most seeds will not be non-gmo. If so, they will be clearly marked on the package, probably on the front. To get non-gmo you need to buy heirloom seeds.
I never knew to look. They are packed for 2013, they say sell by 12/13 on them. Does that mean they are no longer good? If so I will take auction down immediately! Thank you for the heads up. F B.
