Distribution and habits
It grows in bushes or under pine forests at an altitude of 200 ~ 3 100 meters in Yunnan-Guizhou Plateau.
I like cool and humid climate and hate hot and dry. It requires a semi-shady environment with good ventilation, sun protection in summer, cold protection and warmth in winter. The producing area is acidic soil, so the pH value of cultivated soil should be 5.5 ~ 6.5, which is rich in humus, loose and well drained. This species is a fat-loving flower, but avoid thick fat, otherwise it will lead to the death of rotten roots.
Commonly used alum fertilizer water, 2 ~ 3 times a month. Phosphorus and potassium fertilizer should be applied during bud differentiation and pregnancy. Also, pay attention to watering. Although this variety likes humidity, it is not tolerant to waterlogging, and too much water is easy to rot its roots. So the principle of watering is to keep the soil moist when it is dry.
