Armitage says this is hardy Z5-7 in eastern North America. It's unhappy with hot summers of the US southeast, and a better bet for the west coast.

G. cinereum ssp. subcaulescens is now generally treated as a separate species, G. subcaulescens.

I just got this plant and on the package and everything I've read about it it's good up to a zone 5. So I'm thinking that zone 7 as listed here on the plant file is a little underestimated.
Besides being that most of the Hardy Geraniums are good through a zone 5 anyway.
I'm a zone 5b so I'm hoping that all the info I've read is right I'm really betting on it.

A selection from the type plant which hails from the Balkan Peninsular and Turkey. It is less shocking in colour than the type and doesn't have the full black eye either, just a dark central area. It is as hardy though, unlike 'Splendens', which is a little less robust
