A few years ago a volunteer grew in my garden. I identified it as a prickly poppy. It bloomed, but did not self-seed. However it lasted for three winters before failing to regrow. The flowers had pure white petals. I would like to try this again.

This poppy is endemic to Hawaii and was first collected in 1779 by a botanist on Captain Cook's expedition. It grows on the dry rocky soils of the leeward side.

I collected seed and brought it to my garden where it frugally self seeds and germinates in full sun on bare dry soil after a good rain most often. I have just allowed to wander around on its own after my intial introduction as a pleasant surprise when it shows up.
