Discussion

Cydonia oblonga is cultivated in the United States, particularly California and New York, for its fruit and less often throughout temperate North America as an ornamental and a curiosity. It is often used as a dwarfing rootstock for pears. In the Mediterranean regions of Europe, South America, China, and elsewhere, it is cultivated for the golden yellow aromatic fruit that is rich in pectin, making fine jellies and preserves. The fruit is also used in pies, turning deep red when cooked.
