The list is very long. Here is a little information

" A BRIEF HISTORY OF THE “ASIAN PEAR”

Asian pear has a long and rich history that can be traced back to Ancient China.

This fruit has been enjoyed by people worldwide for centuries, and its health benefits are well known. Let’s explore the brief but fascinating history of the Asian pear (Pyrus pyrifolia), a member of the Rosaceae family, which also includes apples, cherries, and quinces.

The fruit is native to China and has been cultivated for over 4,000 years. The first recorded mention was in 28 BC when Chinese philosopher and politician Dong Zhongshu wrote about the fruit in his work "Lunheng."During the Tang Dynasty (618–907 AD), the Asian pear became a popular symbol of prosperity and good fortune.

The fruit was often given as a gift to government officials and nobles. In Japanese culture, the Asian pear is known as the “fruit of longevity” due to its long shelf life.

Buddhist monks who traveled to China introduced the fruit to Japan in the 8th century. During the Edo Period (1603–1868), the Asian pear became a popular snack food in Japan. The fruit was often eaten sliced and dipped in soy sauce. Today, known as nashi, it is still a popular food in Japan.

The Asian pear was introduced to Europe during the 16th century when Portuguese traders brought the fruit back from China. The first recorded mention of the Asian pear in Europe was in 1597 when Italian botanist Andrea Cesalpino wrote about the fruit in his work “De Plantis.” It quickly became a popular European garden plant and was introduced to North America in the early 1800s."
