Updated July 30, 20261 min readCited sources

Kumquat is a small citrus fruit with an edible sweet peel and tart flesh. Native to southern China and eastern Asia, it is grown in subtropical and warm temperate regions worldwide.

What it is

Kumquats are the smallest citrus fruits, growing on evergreen shrubs or small trees in the family Rutaceae. They were historically classified in the genus Fortunella. The English name comes from Cantonese words meaning “golden orange.” The fruit is typically oval or round, resembling a miniature orange, and is eaten whole—peel and all.

Where it grows

Kumquats are native to southern China and eastern Asia and have been cultivated for centuries in Japan and Southeast Asia. They are grown in subtropical regions such as California and Florida. In Canada, kumquats are mainly available as imported produce, though they can be kept as ornamental or container plants in greenhouses or indoors.

Common uses

Kumquats are eaten fresh, often whole because the peel is sweet while the flesh is tart. They are also processed into jams, jellies, and preserves. Their versatility and cold-hardiness compared with other citrus make them a distinctive addition to both fresh and cooked preparations.

In short

  • Kumquats are among the smallest citrus fruits.
  • The peel is sweet; the flesh is tart.
  • They are native to southern China.
