Dracunculus vulgaris has been hardy, here in western New jersey. I know 
when it flowers - fortunately at the bottom of the driveway far from the 
house - because I think, "Oh, there must be a dead and rotting 
groundhog. No, it's the Dracunculus." Neighborhood dogs ignore it. And 
I've never seen the black vultures circling over it.

Sauromatum has also turned out to be quite hardy. And multiplying 
enthusiastically too. They are emerging now, flowering, popular with 
flies crawling over the spadix. No stench, not like the Dracunculus.

Judy, happy to report we've finally had rain this evening, a delightful 
4/10th of an inch. And very welcome too.
