Ipheion uniflorum hardiness

I can confirm hardiness at these conditions for Ipheion uniflorum too.
Plants evolve to survive the most extreme condidions they may encounter.
Even if this only needed once in a thousand years, in their natural
habitat, -a useful fact for gardeners.

following conditions: -20 C night/ -15 C day for 10 days continuously
without snow cover (last winter).
