Sauromatum on the wiki and in the garden

I've also been growing Sauromatum venosum outdoors here in NW Arkansas
(nominally z6, but with the odd z5 temps to -20 F [-28 C]) for at least 20
years now. No special protection or handling. I know people farther north who 
also grow them outdoors successfully. They have just finished flowering here.

They'll set seed, which I know is fertile only because I germinated a few 
before offering it to others. I suspect they germinate rarely if at all in the 
garden, otherwise I'd have thousands by now instead of mere hundreds ...

I do have a start of one of the "giant" strains, which I've not yet tested 
outdoors. Anyone have any experience with these? Are they equally cold hardy?
