Epilobium amurense subsp. cephalostigma is a perennial plant found primarily in Asia. The following describes the growth characteristics, propagation methods, cultivation methods, garden uses, and major pests and diseases, as well as control methods.

Growth Characteristics:

Epilobium amurense thrives in moist environments and prefers sunny locations. It grows to a height of approximately 30 to 60 cm and produces small purple flowers from summer to early autumn. It prefers well-drained soil that is slightly acidic to neutral.

Propagation Methods:

 - Planting: Spread the seeds thinly over the soil and lightly cover them. For root division, plant in a prepared spot with adequate spacing.
 - Watering: Water thoroughly for the first few weeks to ensure the roots establish well. Afterwards, water and care for the plant about once or twice a week.

Important Pests and Control Methods:

Stone Needleflower is relatively resistant to pests and diseases, but it can contract fungal diseases due to overwatering or poor ventilation. To control these diseases, manage watering thoroughly and maintain spacing between plants to ensure good ventilation. If a disease occurs, treat it using appropriate pesticides. Additionally, to minimize insect damage, regularly check the condition of the leaves and take immediate control measures if any abnormalities are detected.
