Dimocarpus longan is auspiciously named Longyan in China, due to its shiny, dark seed, resembling a dragon's eye.

Importance
In Florida, climatic requirements of longan are particularly suited to the southern part of the state, and new longan plantings have increased over the past ten years to reach approximately 1,600 acres with the prospects of further expansion. About 90 percent of the longan production in Florida is in Miami-Dade County with the remaining acreage scattered in various south Florida counties (Palm Beach, Lee, Sarasota, etc.). 12
Historically, longan was considered an unreliable bearer, and that limited expansion of the industry. However, with the discovery of the flower-inducing chemical potassium chlorate, growers can now improve flowering during the normal crop cycle (July–August) as well as produce off-season fruit; there is potential of year-round production. 12

Origin

The longan is native to southern China, in the provinces of Kwangtung, Kwangsi, Schezwan and Fukien, between elevations of 150-450 m. It thrives much better on higher ground than the lychee and endures more frost. It is rarely found growing along the dykes of streams as is the lychee but does especially well on high ground near ponds. The longan appears in these regions more often but it, too, cannot stand heavy frosts. After a long period of cool weather over the 3 winter months, with no frost, longan trees bloom well. Blooming is poor after a warm winter. 14
In 1954, rare-fruit pioneer William Whitman introduced the superior 'Kohala' cultivar from Hawai'i. 9

Description

The longan is a large evergreen tree that is becoming very popular in South Florida landscapes. Native to southeast Asia, this beautiful tree produces showy clusters of grape-like fruit during the mid-to-late summer. Trees can grow as high as forty feet or more and are well-adapted for a wide variety of soil and moisture conditions. 3

Leaves
Leaves evergreen, leathery, wavy, glossy-green on the upper surface, minutely hairy and greyish-green beneath.
New growth is wine-colored and showy (Fig. 4,5). 14

Flowers
The inflorescence is commonly called a panicle. Flowers on the panicle are held on numerous cymules on the many branchlets of the panicle. The flowers are small and have 5 to 6 sepals and petals, and are brownish yellow or greenish yellow, with a two-lobed pistil and usually 8 stamens. Panicles may carry a few to more than 350 fruit. There are 3 flower types in longan, staminate (functionally male), pistillate (functionally female) and hermaphroditic (bisexual). Flowering in each panicle occurs in progressive openings of staminate (male) flowers first, then hermaphroditic flowers functioning as females and then hermaphroditic flowers functioning as males. 1
Longan flowers are of the best food source for honey, so that honey production is related to longan-growing areas in China, Thailand and Taiwan. 10

Pollination
Bees (Apis and Mellifera spp.) are the major pollinators and comprised 98-99% of the total insect visitors to the flowers. The visits occur mostly during the morning hours, when nectar secretion occurs. Too much rain during anthesis can reduce flower opening and the insect activity needed for pollination. Irrigation after a period of soil water stress is reported to aid in flowering, even though the tree flowers profusely in areas with high water tables. 11

Fruit

The drupaceous fruit are spherical to ovoid, 3/4 to 1 7/16 inches (22–36 mm) in diameter and 0.21 to 0.67 oz (6–19 g) in weight. The peel is tan or light brown, thin, leathery and smoother than that of the lychee. The pulp is whitish and translucent; thin in large seeded fruits and medium thick to thick in others. Fruit have 1 seed; globular and shiny, brown to dark brown. The pulp does not adhere to the seed and is flavorful and sweet with 12-21% soluble solids. 1

Varieties Page
Reliable bearing is the major production problem for longan throughout the world. In Florida, 99% of the acreage is planted with 'Kohala'. Other cultivars have been introduced, some for a long time and others recently. A number of new and re-introductions including 'Edau' ('Daw'), 'Chompoo', 'Haew', and 'Biew Kiew' are evaluation by several institutions and producers. However, nothing superior to 'Kohala' has been identified. 1
One of the recently introduced cultivars is named 'Diamond River'. This cultivar is from Thailand and is reported to fruit every year, be precocious, produce off-season, and produce a sizeable late season crop. However, fruit quality is only fair and the tree is very susceptible to limb breakage. 1

Thinning

Longan fruit set varies greatly among trees and years. In some years, individual longan panicles set in excess of 300 fruit. However, panicles with 150 or more fruit usually produce small fruit. Removing about 50% of the set fruit during the spring usually results in a large increase in fruit size. Thinning is best done when fruit are 1/4 to 1/2 inches (6-12 mm) in diameter and consists of removing one half to two-thirds of the distal (terminal) end of each panicle. 1

Harvesting
The longan harvest season in south Florida is from the middle of July to early September but is mainly in August. At maturity, the fruit will be an intense tan color. The main ripeness indicator is pulp sweetness; this occurs before removing the fruit from the tree. Fruit that is 1¼ inches (32 mm) or greater in diameter with good flavor is most desirable. Once removed from the tree, the fruit will not increase in sweetness. 1
Time flowering to harvest: 140-190 days. 1

Propagation
Trees can be seed-propagated, but seedlings do not come true to type and may take up to six to eight years to start bearing. A more practical way of propagation is by air layering, which takes about eight to ten weeks, or veneer grafting on seedling rootstocks. Air-layered trees generally will bear within one to two years after being planted and grafted trees may bear the next year after being planted. April through August is the best time to perform this task, and roots begin to form within 10 - 12 weeks. No special or improved rootstocks have been reported. 3,8

Types of Propagation, Edible South Florida

Pruning
At planting or soon afterward, remove limbs with a narrow crotch angle. To force new shoot growth and increase the number of new shoots either bend long upright limbs to a horizontal position by tying or head back upright limbs. Shoot tip removal (removing 1-2 inches of the end of new shoots), once or twice during spring and summer will increase branching and make the tree more compact. As trees mature, most of the pruning is done to control tree size (height and width), and to maintain production of the lower tree canopy and light on all sides of the canopy. If the canopy of the tree becomes too dense, selective removal of some branches will increase air circulation and light penetration. 1
Trees kept 10 to 15 ft high (3.1–4.6 m) and 15 to 30 ft (4.6–9.1 m) wide are easier to care for and pick. They are also less likely to topple during strong winds. If the canopy of the tree becomes too dense, selective removal of some branches will increase air circulation and light penetration. 1

Fertilizing
See Longan Growing in the Florida Home Landscape, University of Florida pdf

Irrigation
Withholding or reducing watering during the late summer/early fall through winter is recommended to stop or reduce excessive vegetative growth and enhance subsequent flowering during the spring. However, for optimum fruit production and quality, regular irrigation is recommended from flowering through harvest. 1

Pest Page
Longans have a few insect problems in south Florida. The most common pests are the lychee webworm and several scale insects. 1

Disease Page
There are no major disease problems of longan at the present time. Red alga (Cephaleuros virescens) attacks limbs and shoots and is most prevalent during high humidity, warm, rainy weather. Parasitic lichen (Strigula sp.) may parasitize leaves. Please contact your local UF/IFAS Extension office for current control recommendations. 1

Food Uses

Ripe fruits, which have a sweet but less aromatic taste than the related lychee (Litchi chinensis), are predominantly consumed fresh. The translucent flesh is used in fruit salads and desserts as well as in savory recipes like sweet- and-sour dishes and stir-fries. Fruits are preserved by canning in syrup or drying. Dried fruits, which have a leathery texture and turn blackish, are used to make refreshing drinks and aromatized teas. The seeded fruits are macerated in alcohol to produce a type of liqueur. 15

Medicinal Properties **
The flesh of the fruit is administered as a stomachic, febrifuge and vermifuge, and is regarded as an antidote for poison. A decoction of the dried flesh is taken as a tonic and treatment for insomnia and neurasthenic neurosis. In both North and South Vietnam, the "eye" of the longan seed is pressed against a snakebite in the belief that it will absorb the venom. 2

Other Uses
The seeds, because of their saponin content, are used like soapberries (Sapindus saponaria L.) for shampooing the hair. The seeds and the rind are burned for fuel and are part of the payment of the Chinese women who attend to the drying operation. 2

General
Fusing the Ancient With the Modern "Longan trees growing near temples in that country (Taiwan)," says Matsumoto, "were found to form flowers and then bear fruit shortly after religious ceremonies in which fireworks were used. This occurred even outside the typical growing season."
Studies reported in 2000 by Chung-Ruey Yen of the National Pingtung University of Science and Technology in Taiwan suggested that a chemical in the ashes of the firecrackers settled in soil around the trees and triggered flowering. 7
