- Temperature: It can withstand cold winters and thrives during warmer seasons.

Propagation Methods
- Seed Propagation: Seeds can be collected after flowering and sown immediately, or sown in the spring after overwintering. Since cold weather aids seed germination, it is recommended to freeze the seeds once.
- Division: It can be propagated by separating new shoots growing from the roots. This is primarily done in spring or autumn. Cultivation Method
 - Soil Preparation: Prepare well-draining soil, and mix in sand or gravel if necessary to aid drainage.

Important Pests and Diseases & Control Methods
- Diseases: Smut, a fungal disease affecting the leaves, may occur. Since this mainly develops when humidity is high, avoid overwatering and ensure good ventilation.
