Flower

 No suggestions on that last post. It's Papaver Somniferum. The Opium Poppy. The one grown to produce Morphine and other opiates. It's not illegal to cultivate this flower in the UK, and it's seeds can be grown cheaply and openly on the internet.  

Doing anything to the plant to obtain the raw opium however is strictly illegal. DZ's plant has now shed it's petals to reveal the seed head which will distribute it's seeds like a pepper pot. Like all poppies they self propagate easily And DZ anticipates more of these flowers eventually.
