Claude and Doug,

I know sometimes nurseries are very lax about naming.  Here around the 
Montreal region, there are many nurseries selling a "Mirabelle" plum, the 
cultivar itself not being specified. Most of the nurseries list it as Ag Can 
Z4, so suitable for my region.

In late summer we have a lot of farmer's markets and supermarkets selling 
baskets of small juicy yellow plums flushed with orange red from Ontario.  I 
always assumed they are a Mirabelle type, or they could be Reine Claudes I 
suppose. Fully ripe, I find them a particularly tasty treat. Hopefully my 
tree will produce similar fruit.

I am a definite newbie but interested in learning. So thanks for the 
interesting discussion.
