Carex rugata

Carex rugata is a perennial herbaceous plant primarily found in East Asia, including Korea, and thrives in wetlands or shady areas.

Growth Characteristics
- Growing Environment: Carex rugata grows well in moist soil and in environments with some shade. It is best to avoid direct sunlight and cultivate it in partial shade.
- Soil Requirements: It grows well in well-drained soil and prefers acidic to neutral soil.
