I grow Cypella pratensis and Cyp. hibbertia here in Canberra, Australia.
We're Zone 8 as far as I know.

I grow them in pots outside (I've just never gotten them into the ground)
which would mean that technically they'd get colder than they would in the
ground (the pot doesn't offer the insulation that the ground offers).  We
get down to around a -8'C minimum (this is the extreme.... generally only a
-6'C) and high 30's ('C) every year and they've both survived for the last
3 years.  Incidentally, they've never been repotted in this time, nor any
special treatment or anything like that.  I keep thinking they've died and
then up they spring again.  One of these days I'm going to remember to
repot them while they're dormant.  I don't like to do it while they're
growing.  Perhaps they might even multiply if I give them some actual

I hope this is some help.
