Can Cherry Blossoms grow in the tropics? If not, anything similar to it that can grow in the tropics?

No, they will not. I've never seen any cherry blossoms growing in the tropics. Japan does not have a tropical climate, except maybe in Okinawa where palm trees grow. Cherry trees need a cold season. There are some beautiful trees that grow in the tropics that will not grow in the same places where ornamental cherry trees grow. They have their own unique beauty unlike cherry trees. Why not grow a mango tree, or a banana and get some delicious fruit?
