What are those rabbits’ foot-like projections on these ferns?

These are rhizomes that help to absorb nutrients and moisture from the surrounding environment. You’ll want to make sure to keep these projections outside of the soil or it may cause rot. They make this fern unique and one of a kind.

Rabbit’s Foot Ferns require bright, indirect light. Direct sunlight may burn the plant and cause browning at the tips of the leaves. These pieces can be snipped off before you relocate the fern to a better location.

Aim to keep the soil moist, without being soggy. This can be aided with a well-draining soil, especially one with lots of peat. Misting the plant can help to keep the plant from drying out.
