Common names
Although all quince species have flowers, gardeners in the West often refer to these species as "flowering quince", since ''Chaenomeles'' are grown ornamentally for their flowers, not for their fruits. These plants have also been called "Japanese quince", and the name "japonica" (referring to ''C. japonica'') was widely used for these plants in the 19th and 20th centuries, although this common name is not particularly distinctive, since ''japonica'' is a

shared by many other plants. The names "japonica" or "Japanese quince" were (and still are) often loosely applied to ''Chaenomeles'' in general, regardless of their species. The most commonly cultivated ''Chaenomeles'' referred to as "japonica" are actually the hybrid ''C. × superba'' and ''C. speciosa''; ''C. japonica'' itself is not as commonly grown.
Species and hybrids
Four named
hybrids have been bred in gardens. The most common is ''C. × superba'' (hybrid ''C. speciosa'' × ''C. japonica''), while ''C. × vilmoriniana'' is a hybrid ''C. speciosa'' × ''C. cathayensis'', and ''C. × clarkiana'' is a hybrid ''C. japonica'' × ''C. cathayensis''. The hybrid ''C. × californica'' is a tri-species hybrid (''C. × superba'' × ''C. cathayensis''). Numerous named
