Winter 2020/21 update

[mikkel]

Most of my seedlings are doing fine.
Directly at the house wall it was -11°C further away maybe a little more or even less.

The seedlings were completely covered with snow. Hard to say what temperature it was under the snow cover.

TaiTri F2 /  Sacaton are in the same condition

BV5 x Ichang Papeda    some are doing fine but most of them suffered heavily

N1tri F2     mostly ok

5Star F2 no harm at all

SP Urban F2  no harm at all

Several Ichang Papeda seedlings         mostly fine 2 plants with frozen branches

without snow cover:

Swingle         stem and branches are ok

several Citrange seedlings        badly injured, some with cracked bark, some seem to be okay and will grow back, the largest was 2m in height

Trachycarpus seedlings underneath are all unharmed.

This unknown hybrid (on its own roots) were completely frozen inside the shed, even the roots but no harm at all.

It had its first tiny fruit last season:

I had a mild , though rather long Winter. Your 5 Star shows much less damage than mine, however, the leaves were damaged much more than the stems, which look quite good at this point. It's quite informative to be able to compare the relative hardiness of the various specimens in your collection. Any that show more than slight damage for you would fail at my location.

kumin I have another (bigger) 5Star F2 that looks exactly like the Swingle above. This 5Star F2 in the picture was covered in snow.

Okay, in that case, yours look a bit better, but not by much. The 5* in the cold frame show very little damage.
