When will litchi ripen? Are there any varieties suitable for planting in Nanjing?

1) Litchi is native to southern China, and is most cultivated in Guangdong, Guangxi, Fujian, Sichuan, Taiwan Province and Yunnan. Harvest the fruit from June to July every year when it is ripe.

2) Nanjing is located between 3 1 14 "and 32 37" north latitude, and litchi needs to be planted between 3 18~28 degrees north latitude, so Nanjing is not suitable for planting litchi.
