Button Fern

Botanical Name: Pellaea rotundifolia

Button Fern 4" Pot for sale

Button fern is a dependable plant that grows well indoors with little care.

Arching fronds densely covered with small, round leaflets makes this New Zealand native an eye-catching accent for any brightly lit room.

Place this fern on a table among other house plants or put it in a hanging basket and allow the trail of leathery, button-shaped leaflets to cascade over the side.

Caring for button fern is easy. Unlike most ferns, Pellaea tolerates fairly dry conditions. One thing this fern won't tolerate is soggy soil.

Watering tip: Allow the top of the soil to dry out slightly before watering again. Fronds that are yellow and wilted are a sign of overwatering. Cut back on water and trim off damaged fronds. Check the plant's roots to see if they have rotted -- if they're mostly black, get rid of it. It's too far gone.

Repot in spring, when the roots have filled the pot. Move the fern to a pot that's only slightly larger. Use a pot with a drainage hole to prevent soggy soil. This is a good time to divide the fern, if you want.

Keep this evergreen in bright, indirect light and constant room temperature. It won't go dormant. With consistent care, it will grow year-round.

High temperatures (above 75°F/24°C) or dry air can cause leaflets to turn brown. Trim off dry leaflets and raise the humidity around your plant.
