Prune plum
subspecies of plant
The prune plum (Prunus domestica subsp. domestica) is a fruit-bearing tree, or its fruit. It is a subspecies of the plum Prunus domestica. The freestone fruit is especially popular in Central Europe.
Names
The fruit is known under various regional names, including "blue plum", "damask plum", "sugar plum", and "German prune". It is called Zwetschge (, plural Zwetschgen) and similar words in German-speaking regions. The German names, and English damson for a similar fruit, are thought ultimately to derive from postulated Vulgar Latin *davascena, altered from damascena, meaning "of Damascus". In Alsace they are known as quetsches and an eau de vie is made with them.

Why this record matters
“Prune plum” is worth following because a concise public description often conceals a longer documentary argument. Here, Prune, plum and subspecies provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 22, 2026. The linked authority identifier is Q13223298. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
