Poppies are illegal to grow, but it's one of those legal "gray areas" sorta like "research chemicals" Yes, it's illegal, but it is sold openly on the internet, and I have never heard of anyone being prosecuted for ordering them, and I spend enough time on drug related websites that I would have. If you grow your own, and get caught, and they don't believe you when you say they are just pretty flowers, then you're in serious trouble.
