Most plants are secure below a layer of snow right now, but a few felt the full force of -29C (-20f) and I snapped a pic of a couple of them:
This P. aureosulcata is completely freeze dried. Most culms have been bent the ground, but I left a few standing to see what would happen. Ugly. I'd say 10% chance for culm survival. I've seen P. aureosulcata listed as hardy to -20f, I'd say that the leaves went at around -10f....
And here is one of the newly plants Ilex opaca. A northern form, the leaves are a dark green (it's a bad pic)... I'm expecting the leaves to drop but, hopefully, it will leaf out again... I've gotta think that these northern forms would experience -20f occasionally in the wild...
Cheers.

I hope they both come back in spring from beneath the snow level.

If you drink, don't drive. Don't even putt.

Thanks guys...
The bamboo will inevitably return, it was more an experiment to see how the culms would take the true zone 5 cold... Not well apparently.
The holly will, I hope, leaf out again in spring... I know it's tough on them to lose their leaves, but these fellas (and gals) are from the northern fringe of their range, so should be able to stand -30C, at least occasionally. I think that the lack of a root system is what's frying them this winter... I would expect that similar cold in 3-4 years time would be shrugged off much more easily.
