Can Rooguchi stand -20 F?
Last year I planted a Rooguchi which did very well. I've read that it isn't as hardy as many other clematis, and that it's hardy to just a zone 6, but I hadn't seen much below 0 F in over a decade so didn't worry about it. This winter is the coldest, windiest, nastiest I've seen in a very long time and it dropped down to -19 F.
If you were me, would you order another now, while there's some good sales going on, and plant it in a much more protected spot, or do you think it stands a high chance of surviving? If I get another, it means something else has got to go.
