The morphological variation of leaves of orchids often makes their plant types obviously different from those of normal orchids, thus showing different ornamental characteristics. The shape variation of orchid leaves mainly includes: dwarf grass (the plant is obviously shorter than the normal plant, and can grow and even bloom normally), dragon grass (all the leaves of the plant are twisted into a spiral shape), short leaf round head (the length is shortened and the tip is rounded), toad skin (the leaf surface is wrinkled) and crystal mouth (the tip of the leaf is thickened, folded in half, the pocket is triangular, and the surface is covered with a thin transparent substance). Among these variants, the crystal mouth and short leaf round head are very decorative.

In addition, in the appreciation of plants, leaves and flowers, "rhyme" is emphasized. Rhyme refers to the aura and expression of orchids, which is the most difficult feeling for ordinary people to understand. Because posture, color and fragrance are all expressions of external beauty, they are easy to appreciate, while "rhyme" is a feeling produced in the mind by the fusion of posture, color and fragrance. Only when people change their association with the charm of orchids into their views on some things and some hidden meanings, and realize the character and temperament of orchids, can they truly love orchids, know orchids and appreciate them.
