'Korean Rock' Fern

  • The 'Korean Rock' Fern is highly valued for its toughness and tolerance compared to other ferns, earning its "rock" moniker. Its fronds are highly divided, giving it a lacy, delicate appearance, yet the leaves are firm, leathery, and dark green, providing excellent structure. It grows in a compact, mounding habit, rarely exceeding a foot in height indoors, making it an excellent candidate for small spaces and detailed plantings.

    Native to Eastern Asia, including Korea, Japan, and Taiwan, where it grows in rocky, shaded forests.
    No Flowers: As a true fern, it does not produce flowers. It reproduces using spores that develop on the undersides of the fronds.


  • Low to Medium Indirect Light: Prefers shady conditions and is intolerant of direct sun, which will cause burning. It performs very well in north-facing windows or away from bright light sources.

    Consistent Moisture: Keep the soil evenly moist but ensure excellent drainage to prevent root rot. Allow the top inch of soil to just dry out slightly before watering again.

    Rich, Well-Draining Mix: Use a standard potting mix amended with peat moss, coir, or compost to provide richness while ensuring good aeration.

    Cool to Moderate: Thrives in temperatures between 60°F - 75°F (15°C - 24°C). It can tolerate cooler temperatures than many houseplants, which reflects its hardiness.

    This plant should be fertilized once per month during the growing season (spring/summer) with a diluted houseplant fertilizer.

    Generally considered non-toxic to pets and humans.

  • Hardy in USDA Zones 6-10 (often grown outdoors in temperate climates), making it exceptionally tough for an indoor fern.
