I had a chance to visit the farm of Ahmed Al Kathiri, in Salalah, Oman. He has more than 3,000 kinds of trees from around the world, including Dragon Fruit, Guava, Coconut, Nuni, among others. Kathiri also has coffee trees. Ahmed has had this farm for 22 years and prides himself on the variety of trees. A future goal is to have tourists visit the farm. One could easily spend an entire day wandering around this impressive farm.
