Actually, there are two of them: Papaver rupifragum (Spanish poppy) and Papaver atlanticum (Moroccan Poppy), Truth to tell, I can't really tell one apart from the other. One's supposed to be shorter, but when they're wearing heels, it's really hard to tell...
They have been blooming all summer on very little water. The blooms only last for the day, but then another flower or six unfurls for the next day's show. They will overwinter here, as well as in places as cold as central Montana (USDA zone 4). That's way better than I can do.
They seem to thrive in part-sun or more (I may test their shade tolerance next year). Also, bees, especially carpenter bees, love these babies. I grew these from seeds (pretty easy) and have been saving this year's seed crop. I plan to spread them around in early spring.
And who knows? They may have cross-bred after a romantic night out on the town (I tell ya, those heels can get a girl into trouble) so I'll never really know who's who.
