Discussion

Chaenomeles speciosa is cultivated as an ornamental for its showy spring flowers and, occasionally, for medicinal use. Putative hybrids of C. japonica and C. speciosa are called C. ×superba (Frahm) Rehder. They also are cultivated and may be expected to spread occasionally through the dumping of garden waste. The putative hybrids are difficult to distinguish from C. speciosa.
