Korean Rock Fern

The Korean Rock Fern (Polystichum tsus-simense) is a charming, small evergreen fern known for its glossy blue-green fronds and striking black stems. Native to East Asia and introduced to the U.S. through Florida and Louisiana, the Rock Fern is a beautiful addition to any indoor or outdoor space. Safe for pets, it’s perfect for plant lovers who need a low-maintenance, pet-friendly option.

This fern thrives in low to medium, indirect light, although it can tolerate full sun in cooler conditions. While it can grow in dim lighting, you’ll see less growth and slower color development. It reaches a mature size of 12–18 inches, forming a lovely, compact clump that looks great in any setting.

To care for your Korean Rock Fern, keep these tips in mind:

• • Use moist, well-drained potting mix rich in organic matter.
  • Place in low to medium, indirect light.
  • Water regularly to keep the soil consistently moist.
  • Avoid direct sun exposure in hotter climates.

With the right care, your Korean Rock Fern will thrive and add a touch of elegance to your plant collection!
