The dragon fruit is precisely of the Hycocereus undatus family, thus making it one of the widespread red dragon fruit. Typically, the fruit has red pulp, or red flesh if you like. The fruit originates from the dragon fruit cactus plant, which usually appears like vines. Unlike day pollination done by bees, it is surprising to note that this nutritious and tasty fruit blooms at night where pollination is caused by nocturnal living things such as bats and moths. What is more, it blooms a few times annually, blossoming with the now synonymous huge aromatic buds.
Despite the fact that people avert and dislike bats, they play a very important role in the pollination and formation of these dragon fruit cactus plants. This is because the dragonfruit cactus plant will only come out successfully after a complete pollination process. Note that even dragonfruit plants that carry out self pollination fail to create a dragonfruit cactus if they don’t get the assistance of the bats. In simple terms, the bats carry out a successful and proper pollination process of the dragonfruit cactus plant to bring out the delectable fruits that we relish.
