Rambutan is a member of the family Sapindaceae or Soapberry family of the genus Nephelium L. or nephelium P. There are 124 listed species of which four are accepted but are not listed in the United States Department of Agriculture (USDA) classification. The plant is native to Malaysia and is a closely related to the lychee.
The tree is cultivated throughout the islands and southeastern Asia. Traders introduced the plant to Zanzibar and Pemba and some trees were found in India, Surinam, and regions of South and Central America and the Caribbean. In 1912 rambutan was brought to the Philippines from Indonesia. In 1906 seeds from Java were sent to the United States but were unsuccessfully cultivated. Rambutan is a fragile fruit that does not ship well. The fruit is used in many recipes and is considered a medicinal herb and the seeds render oil for candles and soap. The fruit can be purchased at major supermarkets and online.

How To Grow Rambutan
Rambutan is a tropical tree that does not tolerate frost: temperatures that fall below fifty degrees Fahrenheit will kill a rambutan tree. The trees are grown in warm regions of Florida and California and do well in greenhouses. They can be grown indoors as a container plant in colder climates.
The plant can be started from seed purchased online or at a nursery; if taken from the fruit they must be fresh—no more than one week old and all the pulp removed. Place seed in a pot with drain holes filled with a mixture of sand, soil, and compost and lightly cover it with soil. The seeds will germinate in ten to twenty days. Fertilize the seedling twice a year and keep the soil moist.
Rambutan trees are male, female, and hermaphroditic and need to be grown in groups to produce fruit. Transplant the seedling two to three yards deep and place them approximately thirty-two feet apart. The tree will begin to bear fruit in four to five years.
Rambutan is usually eaten fresh. It can be served as a dessert, either fresh or stewed. The fruit can be made into syrup and preserves. The seeds can be roasted but not eaten raw, as they may be toxic. Other ways to eat rambutan are as an ingredient in pies, ice cream, and fruit ice; they can also make a refreshing cocktail.
