After drying, they appear pale yellow with black stains. The leaves are thin and leathery, arranged in two rows, narrow and round, measuring 5.5-15 cm in length and 1.7-2 cm in width, with a sharp apex and a sheath at the base; The leaf sheath tightly embraces the stem, and after drying, the sheath opening often opens.

They have 8-9 main veins and many nearly transverse branches; Calyx capsule is nearly spherical, about 5 millimeters long; Petals are broadly oblong, equal in length to the sepals but wider, up to 2.8 cm, with blunt tips and short claws at the base. They have 5 main veins and many branch veins; Lips white with purple tips, broadly ovate, about 3.5 cm long and 3.2 cm wide, surrounded by stamens on both sides below the middle, rounded tips, golden yellow base with short claws, densely covered with short hairs on both sides, and one dark purple patch on each side of the labial disc; The stamen is about 5 millimeters long and the base is enlarged; The medicine cap is wide conical in shape, hairless, and has irregular teeth at the front edge.

Dendrobium wardianum Warner is a perennial herbaceous plant that prefers shade and prefers to grow in warm, humid environments with an annual rainfall of over 1000 millimeters and semi shaded and semi sunny conditions. It is best grown in subtropical deep mountain forests with an average temperature of over 8 ℃ in January. The suitable growth temperature is 15 to 28 degrees Celsius, and the air humidity is 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.
