Occurrence
The lime-loving plant prefers dry, light forests (especially pine forests) from the colline to montane elevation as a location . In Central Europe it is often found in the company of Scots pine, especially in societies of the Cytiso-Pinion, but also the Potentillo albae-Quercion petraeae and the Geranion sanguinei. The range includes Europe and the temperate areas of Asia. In the Allgäu Alps, it only rises a little over 1100 meters.
In Austria this species is absent to rare in all federal states.
Others
The species hybridizes particularly with the rough violet ( Viola hirta ).
