- Light
- Partial shade to dappled sunlight, ideally 4 to 6 hours of indirect or filtered light daily.
- Water
- Requires consistently moist soil during the active growing phase. Reduce watering significantly when the foliage begins to die back naturally during the dormant period.
- Growth
- Herbaceous perennial growing from a rhizome system, reaching heights of 2 to 3 feet with a clump-forming spread that expands via underground growth over time.
Care instructions
Grow in warm, humid conditions with consistent moisture and rich, well-draining soil. Provide partial shade to protect from harsh afternoon sun, and feed with a balanced organic fertilizer during the growing season.
