Button Fern
Pellaea rotundifolia
The Button Fern is a compact, ground-hugging fern with rows of small, round, dark-green leathery leaflets arranged along arching fronds — you'll see immediately why someone called them buttons. Unlike most ferns, your plant tolerates drier conditions and lower humidity, making it one of the more forgiving ferns for indoor growing. The frond stems darken to a burgundy-black as the plant matures, which creates a nice contrast with the deep green foliage.
