This is a small deciduous species of cherry tree that is found in BC, Washington and Oregon (Jacobson and Zika 2007). It is a hybrid between Prunus avium and Prunus emarginata, and was first described for the Pacific Northwest by Arthur Lee Jacobson and Peter F. Zika. They describe it as follows: "It is intermediate in morphology, differing from P. avium in its pubescence, more slender leaves, smaller flowers, and peduncled inflorescences. It can be separated from P. emarginata by its broader leaves with coarser teeth, larger flowers with weakly notched petals, and occasional umbellate inflorescences." (Jacobson and Zika 2007).
