Dragon fruit - The pitaya (also known as pitahaya, dragon fruit, huo lóng guo, strawberry pear, nanettikafruit, or thanh long) is the fruit of several cactus species, especially of the genus Hylocereus, but also see Stenocereus. Native to Mexico and Central and South America, these vine-like epiphytic cacti are also cultivated in Southeast Asian countries such as Vietnam, the Philippines, and Malaysia. They are also found in Taiwan, Okinawa, Israel, and southern China. The pitaya only blooms at night; they are large white flowers that are often called Moonflower or Queen of the Night.
