Button Fern
Pellaea rotundifolia
The Button Fern is a compact, evergreen fern grown for its distinctive round, button-like foliage. Native to New Zealand, Pellaea rotundifolia features dark green, leathery leaflets that are densely packed along mahogany-colored, wiry stems. Give it medium light, moderate humidity, and steady moisture in a planter with drainage holes.

Care Notes
Light
This fern thrives in medium to bright indirect light
Avoid direct sunlight as it can dry out and burn the leathery leaves.
Water
Water your Button Fern when the top inch of soil feels dry to the touch
It prefers to remain consistently moist but never soggy. Use a planter with drainage holes to prevent root rot.
Humidity and Temperature
While it can handle lower humidity than most ferns, it still benefits from moderate levels
Grouping plants together or using a pebble tray is recommended in dry climates.
Soil and Planter
Use a high-quality, well-draining potting mix, ideally peat-based with perlite or coarse sand for aeration
Seasonal Care
In winter, reduce watering as the growth slows and keep the plant away from cold drafts or heating vents
Common Issues
Brown edges on leaves usually indicate underwatering or very low humidity, while yellowing fronds may suggest overwatering
