in Calgary. My daughter said she was at 3 nurseries and none of them have any. She flies home on Thursday.
I got mine from Gardenimport last year in case you can't find it any where else.
We found one at Rona last year and it was beautiful all summer. We are watching it carefully and hope it made it through through the winter.
I got mine from Home Depot 2 years ago, as I couldn't find any in the local plant nurseries.
