Native to Fiji, this soft, rhizomatous fern is more tolerant of low humidity and cooler temperatures than most other house ferns.
Davallia fejeensis (Rabbit’s Foot Fern)
Hardiness Zones: 10-12
Height: to 1 meter (3 feet) tall fronds
Diameter: to 45 centimeters (18 inches) wide fronds, spreading to several meters/feet
Growth Rate: moderate
Root System: spreading rhizome
Tolerates: herbivores (rabbits)
Problems (major): Chemical spraying, full sun, and low humidity all damage the foliage significantly. Rhizome rot is commonly fatal.
Problems (minor): scale, botrytis, aerial blights, limp/wilting fronds (overwatering, underwatering), yellow/brown fronds (too warm, humidity too low), gray mold, air pollution
Poisonous: Many ferns contain carcinogens, which may be harmful if ingested.
Soil requirements: prefer moist, slightly acidic to neutral (pH 6.5-7.5), well-drained soils composed of peat or half- soil/half leaf-mold mix or sphagnum moss
Air requirements: requires high humidity (above 50%), intolerant of pollution
Watering requirement: moderate
Sun requirement: partial shade, prefer north or eastern windows
Fronds: triangular, deep green, 3- or 4-pinnate, soft, gray-green stalks to 22 centimeter (9 inch) tall, easily removed once dead, to 60 centimeters long by 45 centimeters wide (24 inches x 18 inches)
Spores: on underside of fern, cinnamon-brown color
Rhizome: creeping, thick (to 1 centimeter (0.5 inches) in diameter), pubescent, cinnamon/reddish-brown, white when new
The creeping rhizome is fairly unique among ferns and serves as an excellent medium for dividing these plants.
Rabbit’s Foot Ferns are typically grown as ornamentals.
