Cystopteris fragilis, commonly known as the brittle bladder-fern, is a delicate fern native to temperate regions. It is often found in rocky crevices and moist, shaded areas. This perennial or lithophyte plant is known for its finely divided, lacy fronds and its ability to thrive in challenging environments.
Cystopteris fragilis prefers moderate temperatures and high humidity. It thrives in bright, indirect light and should be kept in evenly moist soil. Avoid direct sunlight as it can scorch the delicate fronds. This fern is relatively easy to care for and can adapt to indoor or outdoor environments.
土壤
The brittle bladder-fern prefers loamy soil that retains moisture but also drains well. Ensure the soil is rich in organic matter to support its growth. Good drainage is essential to prevent root rot.
