Comments: Button ferns make excellent terrarium plants as they prefer to have their conditions stable without fluctuations. If grown as a container houseplant: a drip line, ‘plant-nanny’ system, or self-watering planter with reservoir is recommended. Intermittent waterings can easily stress this fern. Very attractive dainty foliage that is available in a few different foliage sizes. Dies quickly with insufficient humidity.
