Button Fern (Pellaea rotundifolia) is a compact, elegant fern distinguished by its dark green, leathery, round leaflets arranged along thin, wiry black stems. The small, button-like foliage gives the plant its common name and creates a tidy, symmetrical appearance that stands out among more feathery ferns. Native to New Zealand, Button Fern naturally grows in rocky forested areas and coastal woodlands, where it thrives in dappled light and well-draining soil.

Unlike many tropical ferns, it prefers slightly drier, less humid conditions and is well suited for indoor or temperate environments. As a non-flowering plant, it reproduces through spores found on the undersides of its leaflets. Its understated form, clean lines, and dark tones make it a favorite in minimalist and contemporary plant designs. Button Fern is prized for its low, spreading habit and durable foliage, offering a refined, textural contrast to more lush, tropical greenery in gardens and interiors.
