Selenicereus megalanthus, cv. Palora dragon fruit that is yellow and has white, juicy flesh. The fruit is sweet and in high demand all over the world. Many people say it’s the sweetest fruit they’ve ever had.
Palora (It is also sometimes called Amazona, Amazonian or Amazon) is a type of Dragon Fruit that comes from the Selenicereus genus and the megalanthus species. It gets its name from the town in Ecuador, South America, called Palora (comes from the Ecuadorian Amazon of Morona-Santiago Province), where it is grown commercially.
This variety is a lot like its close relative Yellow Dragon, also known as Columbiana, except that it grows faster, the plant is less delicate, and the fruit is more than twice as big.
Ecuadorian Palora Yellow grows in long segments that can be up to four feet long each. Each of the three edges has spines that are about the same size. When they are on the vine, they have spines all over them. But compared to Yellow Dragon, they have about half as many spins, and the fruit is two to three times as big (on average they weigh about 1-1.5 Lbs).
Don’t worry about the thorns on the fruit. When the fruit is ready to be picked, they quickly brush themselves off. The growth is olive to dark green, and as we’ve already said, it grows quickly.
