Galanthus peshmenii is actually quite hardy from my experience. I wintered it just fine in Kansas for one year when the lows got down to ca. -3F with some leaf burn, and I have it outside in east Tennessee with no problem at all. The cold does limit seed set on this species and reginae-olgae though.

And when one does make an effort to share, it's very disappointing to
have promised some plant (almost impossible to obtain in the USA) to
someone and then have to tell them it has died out; for example, I
promised Galanthus peshmenii to two US galanthophiles, and I'm not
sure it will survive this cold snap, and John Grimshaw was very kind
to send me a start of it some years ago. There is a whole set of
bulbs and Ranunculaceae that are relatively inaccessible to American
gardeners, primarily those that have ephemeral seed, and those of us
who do somehow (!) acquire them must make every effort to propagate
and distribute them. Then when we lose them, we may be able to get
them back; and when we ourselves are gone, the plants will continue
to please others.
