Kumquat - the fruit

Kumquat or cumquat is a small, oval fruit, being approximately the size and shape of an olive. It closely resembles an orange in appearance, but is the only citrus fruit that can be eaten with the skin.

Kumquats belong to the plant family Rutaceae and genus fortunella, named after the botanist Robert fortune who brought them to Europe.

The short trees or shrubs that bear this fruit are 8-15 feet tall, with dark green glossy leaves and white flowers. Depending on size, the kumquat tree can produce hundreds or even thousands of fruits every year.

This plant symbolizes good fortune in Asian countries, and can be grown as an ornamental plant or used in bonsai. It can also be given as a gift during the lunar new year.

The plant is a native to South Asia and the Asia-Pacific region, now grown in different parts of the world.

The different varieties of kumquats include the following :

  1. Round or Marumi kumquat - This variety is mainly used to make jellies and marmalade. The golden-yellow fruit can be eaten as such or cooked. Its peel is sweet, and the center has a sour and tangy taste.
  2. Oval or Nagami kumquats - The fruit ripens in mid- to late winter.
  3. Jiangsu or Fukushu kumquats

Kumquats are much hardier than their other citrus relatives. Though they grow well in hot summer, but can withstand frost down to minus temperatures without injury.

The trees enter into a period of winter dormancy so profound that they will remain intact through several weeks until the arrival of warm weather, when they would give out new shoots and bear the bloom.

They are not grown from the seed but from rootstock of another plant.

Kumquats can be used to make candied snacks.
