Fishbone Fern (Wall) (Nephrolepis cordifolia) is a cascading form of fern recognized for its arching, slender fronds that extend outward in a single direction, spilling gracefully over edges. Its narrow leaflets are arranged in a fishbone-like pattern along wiry stems, giving it a textured, flowing appearance. Also known as Erect Sword Fern or Narrow Sword Fern, it is native to tropical and subtropical regions of Asia and Australia, often found in forest understories, rocky crevices, and streambanks.

The “Wall” form refers to its growth habit—ideal for ledges, containers, or shelf edges—where it naturally drapes down like a green curtain. It spreads through rhizomes and tubers, anchoring itself while reaching outward. Fishbone Fern is valued for its adaptability, ornamental elegance, and ability to soften vertical or angular spaces. Its cascading habit makes it a unique alternative to upright or clustered fern forms, adding a dynamic, flowing layer to indoor or outdoor plantings.
