A recent study of native Prunus fruticosa stands in northern Poland finds that it is disappearing there by "genetic erosion" or "disappearance of typical morphological characters". It hybridizes naturally with Prunus cerasus to form Prunus × eminens,[13] and with Prunus avium to form Prunus × stacei.
These forest plants are brought into closer contact with Prunus fruticosa by the modern disappearance of "contemporaneous sites of the steppe relics" once common in northern Poland, due to forest management since the 18th century, and the planting of stands of Prunus cerasus, which are more prolific in pollen.[14]
