Dragon fruit is a fast-growing vine-like cactus. The fruit is spherical, red colored with notable scales. It has slim rind skin which is protected in scales. The pulp of the fruit is white or red and tastes fairly sweet. Generally, the dragon fruit is deep red in color but some varieties might be pink or yellow. Belonging to the cactus family, it got its generic name from what the locals of Southeast Asia refers to it as dragon crystal, dragon scales, green dragon, and dragon pearl fruit.
