What is a rabbit’s foot fern?
The rabbit’s foot fern (Davallia fejeensis) is a tropical epiphytic fern native to the Fiji islands and surrounding Pacific region. What sets it apart from every other fern on the shelf is its fuzzy, creeping rhizomes — the silvery-brown, scale-covered stems that wander over the pot rim and dangle in the air like the paws of a small mammal. New fronds unfurl from these rhizomes, so a well-grown plant looks as if it’s spilling out of its container in the most charming way. Because the rhizomes are designed to cling to tree bark in the wild, the plant adapts happily to shallow pots, hanging baskets, and even mounted boards.
How much light does a rabbit’s foot fern need?
Rabbit’s foot ferns thrive in bright, indirect light — the kind you’d find a few feet back from an east- or north-facing window, or shielded from the glass on a south- or west-facing ledge. In medium indirect light the plant stays healthy but grows more slowly and fronds may be smaller. The one condition to avoid is direct sun, especially harsh afternoon rays, which scorch the delicate, lacy leaflets and bleach the colour out of the fronds.
How often should you water a rabbit’s foot fern?
Water every 1–2 weeks, letting the top inch of potting mix dry out before the next drink. The trick with this fern is that the rhizomes sit exposed on the soil surface and can dry out faster than buried roots — if the fuzzy paws start to feel papery or slightly shrivelled, mist them directly with a spray bottle. Never let the pot sit in a saucer of standing water, as waterlogged roots cause yellowing and frond drop quickly.
Why does it matter that the rhizomes stay on the soil surface?
In nature, Davallia ferns are epiphytes — they grow on tree bark rather than in soil, and their rhizomes cling to rough surfaces and absorb moisture from the air. Indoors, replicating this means keeping the rhizomes on top of the potting mix, not buried under it. Burying them causes rot. Use a shallow, wide pot or a hanging basket, and press the rhizomes gently against the mix surface so they can anchor while staying exposed to the air.
How do you keep fronds from going crispy?
Crispy tips almost always mean dry air or inconsistent watering. Rabbit’s foot ferns are more tolerant of low humidity than some ferns, but they still prefer average humidity of 40–60%. Placing the pot on a pebble tray filled with water, grouping it with other plants, or running a small humidifier nearby all help. Keep the fern away from heating and air-conditioning vents, which blast dry air directly onto the foliage.
Is a rabbit’s foot fern safe for pets?
Yes — the ASPCA lists Davallia fejeensis as non-toxic to cats and dogs, making it one of the safer fern options for households with curious animals. That said, ingesting large amounts of any plant material can cause mild stomach upset, so keeping the dangling rhizomes out of reach of enthusiastic chewers is still a good idea.
