Dragon fruit grows on trees, but dragon fruit trees are different from fruit trees in the general sense and do not bear fruit on trees like apples and pears. The dragon fruit tree looks like a cactus. It has a main trunk that does not branch when it reaches the top. It is divided into multiple abnormal stems. The dragon fruit grows on the top of the abnormal stem.

The dragon fruit plant has no main roots. The lateral roots are generally distributed in the shallow soil layer, and there are also some aerial roots that can climb and grow. The rhizomes are relatively thick, with three edges, and the edges of the edges are wavy. Generally, dragon fruit will be produced at the end of the rhizome.
