Lots of rock gardeners grow
Lots of rock gardeners grow it here, Cohan (including me). I'm sure it would be hardy for you... A gorgeous plant, as in Trond's example.
A bit late, but do you have any seeds still available?
Yes, I still have some! I don't know whether they still are viable though.
Seems like a pretty cool species, I've maybe seen it before on the fora, but don't recall...
