Description
Gymnocarpium is a genus of ferns belonging to the family Dryopteridaceae. It is native to temperate regions of the Northern Hemisphere, with some species found in Asia, Europe, and North America. The genus comprises about ten species, including some that are commonly known as oak ferns or bristle ferns.The name Gymnocarpium is derived from the Greek words “gymnos” meaning naked and “karpos” meaning fruit, referring to the exposed sori (clusters of spore-producing structures) of the fern.

Appearance
Gymnocarpium ferns typically have deciduous fronds that grow from a creeping rhizome. The fronds are usually bipinnate, meaning they are divided into multiple leaflets that are further divided into smaller leaflets. The leaflets are usually oval-shaped and have a smooth texture. The sori of Gymnocarpium ferns are located on the underside of the fronds and are usually arranged in a linear or oblong pattern. They are covered by a thin, membranous layer called the indusium.
Care Guide
Gymnocarpium ferns prefer moist, well-draining soil that is rich in organic matter. They also require moderate to high levels of humidity, which can be achieved by misting the fronds regularly or placing a tray of water near the plant.It is important to keep the soil consistently moist, but not waterlogged. Fertilizer can be applied once a month during the growing season using a balanced, water-soluble fertilizer.Gymnocarpium ferns prefer partial to full shade and can tolerate temperatures down to -30°F (-34°C). They are hardy in USDA zones 3-9.
Common Pests & Diseases
Gymnocarpium ferns are relatively pest and disease-free, but they can be susceptible to fungal infections if they are grown in poorly ventilated areas or if the soil is kept too wet.
Habitat
Gymnocarpium ferns are commonly found growing in moist, shaded areas such as forests, woodlands, and stream banks. They are also sometimes found growing in rocky crevices or on cliff faces.
