This is the first year growing this plant. It took me some time to identify it as P. dubium. It's a crowded field. My seed was collected from an empty lot.

I love this little Asian poppy, but it might not be for everyone.

Pros: Will happily self-sow in the worst of soils.

Every vacant lot, cracked sidewalk, and unattended pot in Tokyo has this little cutie blooming in May.

This poppy may be banned in some parts of the world, including parts of the US. It is considered a pest by commercial poppy seed growers (somniferum and orientale) in Europe and Africa. From just twenty plants, I harvested about 200 grams of seed this year. So by all means, consider your own local ecosystems before trying this one...
