—At least, that's what I think they are. They are posing as plants, but (1) they are green, and we all know aliens to be green; and (2) they are equipped with some sort of sensor-disk, which looks mightily suspicious. If perchance you have a name for them, I'd appreciate it. They are showing up quite abundantly in Vancouver flower gardens, obviously hoping nobody will notice we are being inundated with green aliens. Thank you.
That's Euphorbia characias subsp. wulfenii, still better known to most gardens as Euphorbia wulfenii ( http://www.botanicalstockphotos.com/img17684.htm ).
But definitely alien (in Canada) . . . you can tell by the way they bleed poisonous white ichor when cut ;-)
Ah, it appears that I may have made a slight slip. From the Mediterranean, rather than from a galaxy far, far away. Thank you very much, all, for your help. These are really intriguing plants, and we see them often on our local walks. It is good to have a name for them.
They do seem pretty far out in their reproductive structures. For instance, see the description and drawings at euphorbiaceae.org.
