This is one of those bizarre serendipitous things that happen every so often...
We've been feeding our wild birds for a couple of years now, and one of those feeders contains birdseed.
One day this beautiful flower popped up beneath the feeder! Whilst it rained most of that day, the sun broke through the clouds just before sunset lighting up this poppy perfectly! I happened to be looking out of the window at the time, so I grabbed the camera and tripod and rushed out to photograph it!
I believe, but can't guarantee, this is Papaver somniferum; the same type of poppy that is used to make Opium. It's an interesting irony that something so beautiful can be deadly in the wrong hands...
