Dear all,

I wonder how it is possible, that Ipeion uniflorum is able to survive winter in Central European zone 6 climate, where I live. It is said in the PBS viki that I. uniflorum grows wild in Uruguay. The difference between winter in Uruguay and in Poland is enormous. May be, it also grows in mountains in Argentina?? - this migot help me understand hardiness.

I can confirm full hardines in the following conditions: -20 C night/ -15 C day for 10 days continuously without snow cover (last winter). Flowers and increases very well despite partial shade. Autumn laeves are not prone to severe winter damage. This year we have -25 C night - will see in the spring.

One of the latest flowering spring bulbs in my garden.

Certainly more winter hardy than some seemingly hardy species, like Galanthus woronowii
