Your experience with "Edna Bergman"

I saw a small but well branched specimen at a nursery today. I would like to hear of real world examples of this particular maple.

 

There is a thread with photos of this cultivar here:
Acer palmatum 'Edna Bergman'

 

Thanks Alain. (There does not seem to be many references to this particular variety in this forum).

I am hoping it will be hardy in my location i.e. zone 5 Canadian as I did make the purchase and have already planted it.

 

Looking beautiful as it is now.

It should be all right when planted in the soil : most cultivars are supposed to stand/support -25° C, more or less.
