Most northerly overwintered edible Gunnera?

I was surprised to see two Gunneras (both tinctoria/chilensis and manicata) outside at the Ringve Botanical Gardens in Trondheim at the weekend.  Reidun Mork​ told me that they had used the same overwintering technique as they used at the Copenhagen Botanical Gardens, where she used to work. I knew exactly what she meant as I’d taking a picture in Copenhagen of this in early May (second picture). I’ve never seen overwintered Gunnera so far north before. Gunnera tinctoria is one of the 80 in my book and has special significance locally as the genus was named after Trondheim Bishop Gunnerus (by Linnaeus).
I must have a go at overwintering my pot grown specimen…

  1. We have a huge one on our estate in NE Scotland, Morayshire. It comes back every year without any special attention.
