The Pellaea’s button¬shaped leaflets are unlike those of any other fern. Also unusual are the diminutive size and prostrate habit, which mean that the plant can be effectively used in bowl arrangements, bottle gardens and terrariums. Requiring a fairly high level of humidity, it grows well in close, associated plantings and can tolerate other plants growing around and through its foliage. When separating the rhizome for propagation, moisten the compost well first. The sections of rhizome, with fronds attached, can then be teased apart and cut away quite easily.
