The foliage is exactly the same as that of the Opium Poppy, but I've never seen one with a pink and purple flower before (and look at all that fringing on the petals), so I'm guessing it must be a cultivar.
So beautiful, and the bees were just loving them.
Papaver somniferum is the Opium Poppy's botanical name. It means "sleep-bringing poppy", which refers to it's sedative properties. I would've been boiling the seed-heads up for a foul-tasting poppy brew at one time, but I'm better behaved nowadays.
