Growth habit:
Dendrobium wardianum Warner is a perennial herbaceous plants, like a cool and pleasant in warm, wet, at more than 1000 mm annual rainfall, Yin and Yang, the environment of suitable growth temperature of 15 to 28 degrees, is suitable for growth of air humidity of 60% above, not very strict with techniques namely, wild in loose and thick bark or more trunk growth, and some also grown in the cleft.It is an aerial rooting system, which mainly requires good root permeability, and the substrate used should be able to ventilate and filter water. Under the appropriate temperature and humidity, the growth speed is fast and the survival ability is very strong.In late spring and early summer every year, inflorescence is extracted from the upper segment of biennial stem.
