Yes my Mirabelle is of quite good quality, and I would say more than just 
"suitable" for fresh eating when well ripe. The racoons are also very found 
of it so I usually have to harvest a bit before full maturity. It ripens 
about a week later than Mont-Royal.

Next year I intend to take close-up pictures of the flowers and count the 
stamens - I read in Plums of NY that P.insititia have a different number of 
stamens than P.communis, so hopefully this test should confirm if it is 
really a Mirabelle. If you want, I could sent you a picture off list - I 
have a nice one with Mirabelle and Blue Damas side by side to compare sizes.
