Prunus domestica subsp. syriaca. Mirabelle plum. I stratified hundreds of plum pits from a tree with good tasting fruit. I want to try and grow hundreds of seedlings to try and find one that performs better here.

Mirabelle plum trees normally don't manage to set fruit where i live. All seeds came from one tree in germany, which might be less good than from a local tree here in brittany, and i don't know how much seedlings can vary genetically. It's an experiment to see if i can find better adapted varieties in mass sowings of mirabelle plum pits of one tree.
