The large, so-called dwarf tree fern from Fiji will tolerate a certain amount of dry air indoors. The fronds are carried in a rosette and can be either sterile or fertile, reaching 3 ft. (90 cm) long x 1 ft. (30 cm) wide. The shiny, green leaflets are slightly drooping. As it grows, a scaly black trunk develops, up to 3 ft. (90 cm).
Size: Height 4 ft. (1.2 m), spread 3 ft. (90 cm).
Light: Indirect sunlight.
Temperature: Warm; preferably above 60°F (15°C).
Moisture: Keep very moist. If the temperature falls below 55°F (12°C), reduce watering to a minimum.
Feeding: Give half-strength liquid fertilizer once a month in spring and summer.
Propagation: Remove offsets, if they are produced; otherwise use spores.
Special needs: To maintain adequate humidity, place the pot on a tray of moist pebbles.
