Some facts of Longan
Also known as the dragon’s eye, the longon is very popular in china as both afresh or dried fruit and in oriental medicine. Native to southern china, the fruit is growing in popularity in the west with orchards being developed in Hawaii and Florida. There are also many trees found in India.

The Longan was introduced into Florida in 1903 but never became popular until the kohala variety was introduced from Hawaii in 1954. The recent named Egami variety is one of the more popular types of longon in Hawaii. Full grown trees given may yield 400 to 500 lbs of fruit in good years.

The longan tree is a symmetrical, evergreen tree with dense dark green foliage. Depending upon climate and soil type the tree may grow over 100 ft (31 m) tall. However, in south Florida, trees typically grow to 30-40 ft (9.1-12.2 m) in height and width. The crown tends to be round or oblong and the bark is corky.

Longans are much eaten fresh, out-of-hand, but some have maintained that the fruit is improved by cooking. In China, the majority are canned in sirup or dried.
