Soldanella

[Catwheazle]

Hi,
i try to grow Soldanellas. Germinating and growing in spring  and summer was ok, but in last winter they lost most of leaves. They seemed to dry out , in weeks of stange frost without snow. Their pots were wet, but frozen. This winter i want them put in an styropor box, to prevent drying. Possible or better ideas ?
greetings

How do you cultivate your soldanellas ?

..... sorry ! I dont noticed, that i had posted these theme a year ago :-( At the moment i only have access with my handy, so using this forum is complicate.
to the older posting: the plants i got outside didnt survive. Only the plants in pots.
