Pellaea rotundifolia, button fern, is a compact New Zealand fern with wiry, arching fronds bearing rows of small, rounded, dark green leaflets. A popular terrarium and indoor plant, it is distinguished by its neat, button-like pinnae and more drought-tolerant nature compared to most ferns. For sale in St. Augustine, FL from $7.95.
Good planting window.
Active growing season.
Ideal planting window.
Retains foliage through winter.
Grow in bright indirect light or dappled shade; avoid prolonged direct sun, which scorches the delicate fronds. In NE Florida, a shaded patio, north-facing bed, or understory position is ideal. Unlike most ferns, it tolerates lower humidity.
More drought-tolerant than typical ferns — allow the top inch of soil to dry between waterings. Overwatering or soggy soil causes rapid decline. In Florida's humid climate, ensure excellent drainage and avoid overhead irrigation that keeps foliage persistently wet.
Use a well-draining, slightly acidic potting mix (pH 5.0–6.0) with added perlite. Feed monthly during the growing season with a dilute balanced liquid fertilizer at half strength. Button fern is best treated as a container or indoor plant in NE Florida.
