Kumquats (Citrus japonica) are a group of small fruit-bearing trees in the flowering plant family Rutaceae. They were previously classified as forming the now historical genus Fortunella, or placed within Citrus sensu lato. The edible fruit closely resembles the orange (Citrus sinensis), but it is much smaller, being approximately the size and shape of a large olive. Kumquat is a fairly cold-hardy citrus.
They are slow-growing evergreen shrubs or short trees, from 2.5 to 4.5 meters tall, with dense branches, sometimes bearing small thorns. The leaves are dark glossy green, and the flowers are white, similar to other citrus flowers, borne singly or clustered in the leaf-axils. Depending on size, the kumquat tree can produce hundreds or even thousands of fruits each year.
The round kumquat also called Marumi kumquat or Morgani kumquat, is an evergreen tree, producing edible golden-yellow fruit. The round Hawaiian varietal, the "Meiwa kumquat", is eaten raw. The fruit is small and usually round but can be oval shaped. The peel has a sweet flavor but the fruit has a sour centre. The fruit can be eaten cooked but is mainly used to make marmalades and jellies. It is grown as an ornamental plant and can be used in bonsai. The plant symbolises good luck in China and other Asian countries, where it is kept as a houseplant and given as a gift during the Lunar New Year. Round kumquats are more commonly cultivated than other species due to their cold tolerance.
