If you contact Dave Wilson Nurseries they should be able to tell you if they sell to any Canadian Nurseries and which nurseries they are.
I have the same problem. I would like a Cupid Dwarf Cherry, but it has not been distributed over here as of yet. I do have Julia, Carmine Jewel and Wowza, The University of Saskatchewan made a deal with “Gardens Alive” here in the USA to distribute dwarf cherry trees, and it included a few new unnamed cultivars that Gardens Alive was allowed to name. , only one so far has been released, Wowza…
No, but I picked up Elephant Heart Scion, and I thought it was that one that was like a pluot?. I myself also found Weeping Santa Rosa to be excellent.
This year I should get to sample for the first time Vermont, Superior, Toka, Lavina, Laroda and some pluots. I did have a few superior plums last year, but they were under ripe. All those plums are supposed to be decent.
