canada wild plum

canada wild plum. I collect seed from all around MB, here is a small accession with some amount of hybridization growing in the greenhouse. I'll keep these to grow out. an accession is just a plant growing from one specific source, you might keep track of it separately if you suspect there's some genetic variation that makes it different in an interesting way. for prunus nigra, I'm looking for trees that grow well in our sandy soil, hold up to the winter extremes, flower early, are true to type in their leaves and fruit. only by collecting seed from various places over time can I build up a germplasm that starts to represent this native plum tree, which is considered the best pollinator for hybrid plums, flowering heavily and lots of pollen, a good tree form with less suckering than american wild plum, and larger fruit.
