Pellaea rotundifolia, the button fern, is a species of fern endemic to New Zealand, where it grows in scrub and forests. It is also a popular garden plant and house plant, tolerating low temperatures but not freezing.
Keep It Alive
- Button ferns like enough water, but detest soggy soil. Let the top portion of soil dry out between waterings. If the fronds are green and not wilted, you’ve found a perfect happy medium.
- House your button fern in a bright or even slightly shady spot, but not in direct sun. A sun-filled kitchen or living room is a good choice.
- Make sure to keep your button fern in a humid environment (ideally, in 50 percent humidity). In winter, when heat and fires in the fireplace dry out the home, be sure to occasionally mist the leaves, particularly when they look droopy.
