Bladderferns (Cystopteris)

Bladderferns

Bladderferns are a widespread genus of ferns found in temperate climates. These diverse ferns vary in size and appearance, as they readily create hybrids with each other. Many genus members are used as ornamentals and were favorites of fern collectors of the Victorian era, so much so that collectors created "fern-fever" in the 1860s that began to threaten the genus. Bladderferns are now protected in Scotland.

Water: Bladderferns thrives in high humidity and consistent moisture, reflecting its forest origins. It prefers evenly moist soil and should be watered weekly. Regular misting enhances growth, making it ideal for indoor conditions with shade and humidity.

Propagation: Propagation of bladderferns is primarily via spore sowing and division, as seeds are not produced. Requires humid conditions, indirect light, and well-drained loamy soil. Challenges include moisture management and mold prevention. Division of rhizomes occurs in spring; spores need a damp, sterile environment for germination.
