A look at Dragon Fruit or Pitahaya. The fruit is produced from a tropical vining epiphytic cactus, Hylocereus undatus, or more recently, Selenicereus. The cactus is grown for its fruit throughout the tropics. It originated in the America’s like all true cacti, but its exact origin is unknown. It is typically grown on a large 6 foot post with a ‘T’ or cross on the top, so the stems can grow up the post and then hang down from the top cross. It is the stems hanging down that produce very large white flowers that open at night and close shortly after sun up. The fruits will start developing shortly after the flowers fade. The flesh of the fruit is either white or deep red depending on the cultivar.
