Polystichum adiantiforme is a fern in the Dryopteridaceae family and a member of the Polystichum genus, a largely terrestrial group. Species in this genus are often found on rocky ground, stream banks and disturbed slopes and commonly form a crown of fronds from a stout, slowly creeping rootstock. Garden use follows those natural preferences: place where the plant can occupy rock crevices, banks or shaded areas that mimic montane or warm‑temperate habitats. Expect a vase-like ring of fronds to arise from the crown as the season progresses.

Polystichum adiantiforme is a fern of the Polystichum genus typically associated with rocky, stream-side and montane habitats.
