The Pellaea rotundifolia is native to New Zealand and commonly called the Button Fern.
Arching fronds densely covered with small, round leaflets make it an eye-catching plant for any brightly lit room. Place this fern on a plant stand among other tropical plants or put it in a hanging basket and allow the trail of leathery, button-shaped leaflets to cascade over the side. Beautiful!
POSITION Keep this evergreen in bright, indirect light and constant room temperature. It won't go dormant. With consistent care, it will grow year-round.
SOIL When choosing a potting mix, bear in mind the plant’s epiphyte habit, growing on other plants in its natural habitat, and choose a very loose, free- draining medium. Bark, grit and pumice or an orchid mix work well. When repotting, it’s crucial not to bury the hairy rhizomes below the surface of the soil. They have trichomes (tiny hairs), which capture water from the air, that also send out roots and shoots.
WATER Water thoroughly, then allow the top 2.5 cm of 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.
MAINTENANCE 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.
Feed during the growing season at a low dosage. There is no need to feed during the winter at all, as these aren’t hungry plants and you could risk damage.
