There's a beautiful fruit-bearing plant that grows only in southern Florida... and sadly, that's because it's an endangered species. Here's how to spot it.

Apple trees aren’t easy to grow because they need consistent care, including precisely timed spraying and pruning, to maintain productivity. Apples also need a certain number of chill hours to make fruit. Chill times for apples range from 500 to 1,000 hours, depending on the variety, and the chill time temperatures need to be between 32 and 45°F.

These extraordinary trees produce fruits that are not only rare but also among the most expensive in the world. These fruits are true treasures of nature.
