Its origin of the South China region and utilization over the medicinal properties, not as a table fruit, the fruit is known as the Dragon Eye. Of South China, the plant is then developed into areas of Thailand, Vietnam, Malaysia, and Indonesia. In Indonesia litchi grows well in areas with altitudes between 300-900 m above sea level. Longan require cold temperatures to stimulate flowering is between 5-22 ° C. According to a researcher that the distribution of litchi cultivation dominant plateau in Java, namely in the area of Salatiga, Ambarawa, Waterford, Mixed, and Magelang. Most of the area has a subtropical rainfall pattern as in Ambarawa, Salatiga, and Mixed. Because it requires such a requirement grows, litchi development in Indonesia is limited only in certain areas. In addition, generally litchi plateau have early production is between 5-8 years old so its development into other areas rather slow.

Growing Conditions.

Compared plateau longan, litchi lowland no special requirements for growth. Longan lowlands can be planted in areas with an altitude of 0-400 m above sea level and does not require extreme temperature differences in order to bloom. Longan lowland especially Pingpong can be grown in almost any type of soil due to the high adaptability. Especially for Itoh, because it is basically a subtropical plant that requires little special treatment.

Varieties.

Varieties that have been cultivated in Indonesia is Pingpong, Diamond River, Itoh, and Selarong (derived from the highlands). Each variety has different characteristics.

Pingpong.

Named longan Pingpong, because under normal conditions the fruit produced is able to reach the size of a ping-pong ball.

Characteristics: Fruit reddish when young and gradually become yellow brown to light brown when ripe ahead, the maximum size of a ping-pong ball. Sweet fruit flavors, reaching 20º Brix levels, average fruit flesh wet, high water levels and large seeds.

Diamond River.

Characteristics: Heading compact and dense, branching is more easily formed, green leaves, erect, yellowish-white flowers and is formed at the end of branching, brownish-yellow fruit fruit size is smaller than the Pingpong sweet fruit flavors and high water content.

Itoh.

Characteristics: Heading dense, sturdy, and compact green leaves with wavy edges, similar to Diamond River but not upright but fell. Longer leaf size. Yellowish-white flowers fruit the size of a Diamond River but the taste is sweet, dried fruit and thick flesh and small seeds.

Selarong

Longan longan varieties originally a native Selarong Bandungan have adapted in low-lying areas and then released into the new varieties in 1998. Litchi Selarong mainly found in the area Selarong Displays District of Bantul Yogyakarta. Characteristics: lush tree canopy and compact. The leaves are green and shiny. Brownish yellow flowers and generally appear once a year in November-December and harvested in June-July. Flowers are formed at the ends of branches branching and especially in sunlight, therefore care and pruning should be done in order to obtain maximum results. Fruits are round brown-yellowish. White flesh, chewy, fragrant and sweet.

Flowering and fruiting patterns.

Longan lowland introduced from Thailand and Vietnam, including early-maturing crops. Seeds of graft Pingpong and Diamond River average flowering under the age of one year while the seeds begin flowering at the age of 2 years. Especially for Itoh, with fertilizer treatment can be flowering at the age of 2 years. Unlike the case with the introduction of litchi, longan Selarong a long flowering age is about 2-3 years and 6-7 years of grafts from seed. Thank you for reading this article.
