4" Korean Rock Fern

Korean Rock Fern (Polystichum tsus-simense)

Korean Rock Fern is a compact evergreen to semi-evergreen fern with glossy, deep green fronds and a tidy, arching growth habit. Its smaller size makes it perfect for terrariums, shaded planters, woodland gardens, or as a lush indoor accent in a cool, humid spot.

Unlike many tropical ferns, Korean Rock Fern naturally comes from rocky, shaded habitats in East Asia and prefers cooler conditions. Keep its soil consistently moist but well-draining for the best growth.

Care Tips:
☀️ Light: Low to medium indirect light or outdoor shade, avoid hot direct sun
💧 Water: Keep soil consistently lightly moist, but never waterlogged
🌫 Humidity: Appreciates moderate to high humidity with good airflow
❄️ Temperature: Prefers cool to moderate temperatures and is more cold tolerant than tropical ferns
🐾 Pet Friendly: Yes
⭐ Rare: No

Fun Fact:
Despite its delicate appearance, Korean Rock Fern is surprisingly tough. It naturally grows among rocks and shaded forest areas, making it a much hardier little fern than it looks. 🌿🪨
