If it also happens to be June or July and you’re really lucky, you might even taste the ancient tree’s fruit, because even after a millennium, the plant continues to bear the sweet lychee that made its species a major agricultural crop in the region.

While the first records of lychee cultivation date back around 3,000 years, ...
