4. Dragon Fruit: Dragon fruit, or pitaya and strawberry pear, is a thick-skinned fruit produced by cactus plants from the Hylocereus species. In Asia, it’s known as dragon fruit because the red color fruit resembles a dragon’s flaming fireball, though yellow-skinned pitayas can be found too. But in case you thought pitaya is native to Asia, it’s not. The cacti that bear dragon fruits are actually indigenous to southern Mexico, the Pacific side of Guatemala and Costa Rica, and El Savador.
