a hybrid plum with some simonii in the parentage (25%)

a hybrid plum with some simonii in the parentage (25%) growing well directly on chokecherry coming into year 3. will be grafting more of this one out as a potential interstem, toka thrives on chokecherry (50% Prunus simonii) but it's basically too vigorous. search for the perfect chokecherry compatibility continues, eventually I'll write this trial up as a paper and just post it on my blog
