Dendrobium crystallinum Rchb. f. is a perennial herbaceous plant that prefers shade. It thrives in warm, humid environments with an annual rainfall of over 1000 millimeters and semi shaded and semi sunny conditions. It is suitable for growth at temperatures ranging from 15 to 28 degrees Celsius and air humidity above 60%. It does not have strict requirements for soil and fertilizer. In the wild, it mostly grows on loose and thick bark or trunk, and some also grow in crevices. Belonging to the aerial root system, it mainly requires good permeability of the roots, and the substrate used should be well ventilated, breathable, and filter water. Under suitable temperature and humidity conditions, the growth rate is fast and the survival ability is very strong. At the end of spring and beginning of summer every year, flower clusters emerge from the upper nodes of biennial stems. After flowering, new shoots grow from the stem base and develop into stems. In autumn and winter, they enter a dormant period.
