Polystichum mayebarae, commonly known as Mayebarae’s Korean Rock Fern, is an evergreen fern native to the shaded, rocky outcrops and forest floors of East Asia, particularly in Japan. This species typically reaches a height of 1 foot (0.3 meters) and a width of 2 feet (0.6 meters), featuring a compact, tufted form. The fronds are dark green, glossy, and leathery, contributing to the plant’s lush appearance throughout the year. While not known for flowers, its evergreen foliage provides visual interest in the garden during all seasons.

Mayebarae’s Korean Rock Fern is valued for its low maintenance and ability to thrive in shaded conditions, making it an excellent choice for woodland gardens, shaded rockeries, and as ground cover under larger plants. It is also suitable for container planting, adding texture and greenery to shaded patios or balconies. This fern prefers consistently moist, well-drained soil rich in organic matter and thrives in part shade to full shade. It is relatively pest and disease-free but can occasionally suffer from fungal issues in overly wet conditions. To maintain its neat appearance, old fronds can be trimmed away in early spring before new growth begins.CC BY-SA 4.0
