Black Prune is a domestica plum of Russian origin recorded in South Dakota station literature. The surviving note is brief, but it places the cultivar in the European plum group rather than the native American plum complex. It also preserves its place in the northern trial record for imported plums [S1].
In the old Station orchard, two Black Prune trees planted in 1888 had, like other domestica plums in that planting, proved shy bearers by the time of this report [S1]. The tree was also described as being in poor condition [S1]. Black Prune is therefore less a story of clear success than a record of how Russian and other domestica plums struggled under these prairie test conditions [S1].
The source does not give a fruit description, season, flavor, or culinary use for Black Prune [S1]. What it does preserve is a management question. The bulletin suggests that the weak performance of these domestica plums may have been due in part to poor affinity with the native plum stocks on which they were worked [S1]. That note matters because it points to rootstock compatibility, not just winter injury or fruit quality, as part of the cultivar's history in the northern Plains [S1].
Black Prune is important in the archive mainly for historical and comparative reasons. It was an introduced Russian domestica plum tested in South Dakota, it bore poorly in the Station orchard, and it may reflect a broader graft compatibility problem for European plums under local conditions [S1].
