The lychee, known scientifically as Litchi chinensis, is a unique tropical fruit. It is the only member of the genus Litchi within the soapberry family, Sapindaceae.

This plant is highly valued for its sweet and mildly tart flavor. It also features a distinctive floral aroma that many people compare to roses. Because of its historical importance and delicious taste, it has been cultivated for centuries. Today, it remains a significant crop in many tropical regions around the world.

The lychee grows on a tall evergreen tree. These trees can reach heights of 20 meters.

The leaves are long and pinnate, meaning they have leaflets arranged along a stem. These leaves are specifically adapted to repel water. This trait is known as being laurophyll or lauroid. The fruit development begins with flowers growing in clusters called panicles. These panicles can reach 10 centimeters or longer. They hold hundreds of small white, yellow, or green flowers. After flowering, the fruit takes between 80 and 112 days to mature. During this time, the skin changes from green to a pink-red color.

There are three distinct subspecies of the lychee. The most common is Litchi chinensis subsp. chinensis, which is the only one used for commercial farming. It grows wild in southern China, northern Vietnam, and Cambodia. The second is Litchi chinensis subsp. philippinensis, found in the Philippines. Locally, it is called alupag or matamata because it looks like an eye when opened.

The third is Litchi chinensis subsp. javensis, which is cultivated in Indonesia and Malaysia. These subspecies are distinguished by their flower arrangements, twig thickness, and the number of stamens they possess.

Humans have a long history with this fruit. Unofficial records in China suggest lychees were known as far back as 2000 BC. Documented cultivation in China dates back to at least 1059 AD. During the Han dynasty, lychees were a popular tribute for the Imperial Court. They were so in demand that special couriers used fast horses to deliver them. In 1782, the French naturalist Pierre Sonnerat officially described and named the species. He published his findings in his work, "Voyage aux Indes Orientales et à la Chine."

This helped introduce the plant to the scientific Western world.

Lychee production is a massive global industry. China is the world's main producer of the fruit. It is followed by India, Vietnam, and other nations in Southeast and South Asia. Other producers include Madagascar and South Africa. The fruit is quite nutritious. A 100-gram serving provides 66 calories and is very rich in vitamin C. Specifically, it contains 72 mg of vitamin C per 100 grams. This amount represents about 79% of the Daily Value.

While the fruit is healthy, the seeds contain methylene cyclopropyl glycine. This substance has been linked to health issues in undernourished children in India and Vietnam.

Different varieties, or cultivars, offer different eating experiences. For example, some cultivars produce fruits with small, shriveled seeds called "chicken tongues." These are often more expensive because they contain more edible flesh. In the United States, many cultivars like Mauritius and Hak Ip are grown. In India, over a dozen varieties exist, such as the Shahi, which has a high pulp percentage. The flavor of the fruit is complex due to many chemical compounds. It contains sucrose, glucose, and fructose for sweetness. It also contains linalool and geraniol, which provide its famous rose-like scent.

The lychee is connected to many different fields of study. In genetics, studies show the plant resulted from double domestication. This means it was cultivated independently in two different parts of ancient China. In agriculture, farmers use a method called air layering to grow new trees. This involves wrapping a branch in a rooting medium like peat moss to grow roots. The plant also connects to culinary traditions, such as the lychee cake in Jamaica. This cake was created by baker Selena Wong in 1988 and remains very popular.
