Korean Rock Fern (Polystichum tsus-simense) The Korean Rock Fern is a graceful, pet-safe evergreen fern celebrated for its deep green, leathery fronds and softly arching shape. Native to East Asia, this compact fern thrives in shaded or low-light areas, adding refined, woodland texture to indoor planters, terrariums, or shaded garden beds. With its slow-growing, tidy habit, it’s a perfect choice for creating lush, serene accents in any space.
