Lovely. We have this growing as native in our forests, but there is also the larger fruited Canadian Saskatoon version grown commercially. I love especially a fruit pie / cobbler made of these, the seeds give a sophisticated bitter almond flavor (cyanide precursor in them, harmless when eaten in moderate quantities).
Jam is delicious too.
But the birds love these - Saskatoon farms have all their trees covered with fine netting and one has to get there inside to pick them
