'Korean Rock' Fern

‘Korean Rock’ Fern – Compact Texture with Woodland Vibes

The ‘Korean Rock’ Fern (Polystichum tsus-simense) is a refined, compact fern prized for its dark, leathery green fronds and elegant, symmetrical structure. Native to the shaded forest floors of East Asia, this fern brings a calm, woodland aesthetic to indoor spaces with its finely textured yet sturdy foliage. Unlike many ferns, it’s more tolerant of dry air and lower humidity, making it a versatile choice for homes and offices alike.

Its manageable size and neat, upright form make it perfect for tabletops, terrariums, and shaded corners that need soft, natural greenery.

How to Care for Your ‘Korean Rock’ Fern

Place your fern in a location with low to medium filtered light, such as an east-facing window or on a shaded shelf. It thrives in a cool, humid environment with well-draining, peat-rich soil. Keep the soil lightly moist but not soggy — watering when the top inch begins to dry out is a good rule of thumb.

While it enjoys humidity, the ‘Korean Rock’ Fern is more tolerant of average indoor conditions than many other ferns. You can increase humidity with light misting or by placing it near other plants. Avoid cold drafts and maintain a steady room temperature for optimal growth.

Clean the fronds occasionally with a soft brush or cloth to remove dust and support healthy photosynthesis.
