Pellaea rotundifolia, the button fern, is a species of fern endemic to New Zealand, where it grows in scrub and forests.[1] It is also a popular garden plant (in zones 8 and 9) and house plant, tolerating low temperatures but not freezing.[2]

Pellaea rotundifolia is an evergreen fern that can have more than 30 pairs of round, dark-green, leathery pinnae on fronds up to 18 in. (45 cm).[1]

It needs acidic and well-drained soil; it does not appreciate the moist, humid conditions that most ferns require so does well with minimal watering.[1]

This plant has gained the Royal Horticultural Society’s Award of Garden Merit.[2][3]
