According to the Records of Confucius's Family Sayings, when he was surrounded by rebel soldiers between Chen and Cai with no way out and his followers' morale wavering, Confucius pointed to the orchid as an example: "The iris and orchid grow in the deep forest, yet do not cease to be fragrant because no one is there; the gentleman cultivates the Way and establishes virtue, yet does not change his integrity because of hardship and poverty."

The leaf color is uneven, with some leaves showing mottling of intermingled light green and dark green, and presenting blister-like spots. Some leaves are deformed; the leaf shape becomes narrower and longer, and in severe cases becomes linear. In some leaf axils, adventitious buds sprout and produce thin, weak small branches with extremely short internodes, and the leaves are narrow and small; the axillary buds of the small branches sprout again and produce small branches and leaves, and in this way they sprout and grow level by level, forming a clustered branch state with dense branches and leaves.
