Hylocereus undatus, the white-fleshed pitahaya, is a species of Cactaceae and is the most cultivated species in the genus. It is used both as an ornamental vine and as a fruit crop - the pitahaya or dragon fruit.
Dragon fruit, also known as pitahaya or pitaya, belongs to the cactus family. It’s a climbing cactus and needs support for growing. The flowers are unique, and one among the largest in the world with a diameter of 25 cm and is about 30 cm long. One more feature of its bloom is: it only opens for one night and exudes an inviting fruity fragrance. Dragon fruit will need to provide a sturdy support in your container. Otherwise, the cactus will grow over the edges of your container and sprawl along the ground until it finds something to climb.
