Phegopteris Calcarea

Calcarea fern, scientifically known as Phegopteris calcarea, is a unique and lesser-known species of fern found in specific habitats across the northern hemisphere. This delicate plant thrives in moist, shaded environments such as rocky crevices and forest floors, where it forms intricate, lace-like fronds. Its name derives from the calcareous (lime-rich) substrates it typically colonizes, showcasing its adaptability to mineral-rich soils. Despite its beauty, the Calcarea fern remains underappreciated and often overlooked in favor of more common fern species. Its presence is an indicator of healthy, undisturbed ecosystems, making it a valuable subject for ecological study.
