My deck is the current residence for this peculiar cactus that my friend Shonna recommended I purchase from the nursery where she works.
I do not know her Latin plant name but in plant-people circles, Eunice is not well-liked. Evidently these flowers smell like rotting corpse. I cannot import a smell file for you to smell it, but I can confirm their odor is nasally offensive.
There are some damn strange plants out there on this planet.
