The Korean Rock Fern, also known as Tsu-sima Holly Fern, is a perennial evergreen plant characterized by its creeping growth and crown-forming rhizomes. This fern thrives in consistently moist or wet soil and should be planted in humus-rich earth, ideally in areas that receive partial to full shade. It favors cooler temperatures for optimal growth.
It's important to note that inadequate drainage can result in crown rot, particularly during the winter months.
