Range DescriptionColchicum arenarium is native to Croatia, Hungary, Moldova, Romania, Serbia, Slovakia, and Ukraine. In Hungary, it is found in the inner lowlands between the Danube and the Tisza rivers. The plant occurs in a single locality in Slovakia in the Čenkovská step steppe National Nature Reserve. There is an uncertain record of a historical occurrence from the sands near Komárno (Mereďa and Hodálová 2011).
It occupies a narrow territory near the northwestern part of the Black Sea maritime zone from Dobrogea to the Podolian uplands in Moldova, Romania and the Ukraine. In the Ukraine, the plant is very rare and only found in the Odessa region at ten sites. In Moldova, the species is known from three localities near the towns Comrat, Chirsova and Chisinau. In Romania, it is found at three localities in the Dobrogea region.
