The three subspecies of Crocus serotinus are most easily distinguished by their corm tunic.   Subspecies serotinus has coarsely netted fibres; subspecies clusii has finely netted fibres; subspecies salzmannii has a membranous tunic splitting into parallel fibres.

All three subspecies can make good garden plants in temperate areas.   Those forms from drier native regions need a drier summer rest.
