The bulk of my vft’s are in two smallish planters. The round one is of cultivars, the square one of wild-types. They stay outside uncovered for most of the winter. If it is going to get colder than 28*F I’ll try to remember to put them in the garage. If it is going to get below 18*F I’ll stick them in the basement. Today I took them out of the garage and began removing last year’s dead leaves. I still have more cleaning yo do. But so far, they look like they came through pretty well.

We had close to 0F this year, maybe it was 4F or so. I have never tried them outside for a natural winter. I have kept them in my detached unheated garage, but I lost a few Sarr hybrids one winter. (I forget the lowest temps for that year and no longer keep those records like I used to.) A few VFT died, but then, those that lived have been selected for a degree of winter hardiness. I have not tried them since that winter.
