Fern Lemon Button (Nephrolepis cordifolia 'Duffii'), also called the Button Fern, is a compact tropical fern native to tropical and subtropical regions of Asia, Australia, and the Pacific Islands. It belongs to the Lomariopsidaceae family and grows naturally on forest floors and rocky slopes where moisture and filtered light are constant.
The leaves are small, rounded, and arranged along arching fronds that typically reach six to twelve inches long. Each leaflet is shaped like a tiny button, bright green, and closely spaced along the midrib. The fronds grow in a dense, mounding habit that stays tidy without pruning.
Ferns in this genus do not produce flowers. Instead, Lemon Button Fern reproduces through spores that form on the undersides of mature fronds in small, dot-like clusters. It also purifies indoor air by filtering formaldehyde and other toxins, and it naturally releases moisture into the surrounding air.
This plant is pet friendly and safe for cats and dogs. Place it in a kitchen or bathroom where ambient moisture is higher, or use it in a closed or open terrarium where humidity stays consistent. You can move it outside in summer to a shaded or semi-shaded spot, though it needs cover from rain to avoid waterlogged soil. Rotate the pot regularly so all sides of the plant receive even light from your indoor source.
