Kumquats are small, citrus-like fruits, that will hybridize readily with citrus, but are not now classed botanically as citrus. The fruits are small and deeply colored, produced on small, evergreen trees that are somewhat hardier than citrus. Fruit shape is round or distinctly oval, the latter being about 1 inch in diameter by 2 inches long. Rind is thin and edible, so the whole fruit may be eaten out of hand. In the United States, kumquats are grown mainly in home gardens as ornamentals. Clusters of the highly colored, attractive fruits are frequently placed in gift packages for the omamental effect. A few trees may be found in citrus orchards, especially of growers catering to gift package trade. Whole fruits, except for seeds, are sometimes made into marmalade.
Production in U.S.: No data. No sizable plantings.
