Kangaroo Fern Lecanopteris pustulata subp. pustulata

The kangaroo paw fern is an evergreen perennial fern that is an accepted subspecies of the polypody family (Polypodiaceae) and is native to Southeast Queensland to Southeast Australia, Norfolk Island, and New Zealand. It is an epiphyte and terrestrial, rhizomatous, creeping, and climbing fern that grows in subtropical climates. This fern can be found growing on the ground, over cliffs, over rocks, over banks and in forests, scrublands, and open areas. It may be used as a houseplant or groundcover. The specific epithet, pustulata, is Latin and means "having pustules." This refers to the "sori" which are clusters of sporangia (structures that produce and contain spores) that are found on the undersides of the plant's fronds. The common name, kangaroo paw fern, comes from the shape of the leaves that resembles a kangaroo foot.

This fern prefers partial to full shade or bright, indirect light and moist, well-drained potting mix with an acidic to neutral pH. Water the plant when the soil surface begins to dry out. Avoid overwatering and do not allow the plant container to sit in a saucer of water. These fern prefer temperatures between 60 to 75 degrees Fahrenheit and a humidity level of 50%. Fertilize the plant once a month with 1/2 strength balanced liquid fertilizer during the spring and summer. This fern can be propagated by the rhizomatous root cuttings or by spores.

The kangaroo paw fern grows 6 to 12 inches tall and 3 to 4 feet wide and has low mounding habit. The rhizomes are long, creeping, and succulent. They initially yellow-green to golden brown, but as the roots mature they become grayish-brown to grayish-black. The fern fronds emerge directly from the rhizomes. The foliage has thick, leathery, glossy, long, slender, bright green fronds with entire, wavy, or lobed margins. The plant is non-flowering and is reproduced by spores that are pale and have a wart-like projection. 

This plant requires moderate maintenance and will provide a tropical feel to your home or office either as a container plant or hanging basket. Consider this plant as accent for an entryway, bathroom, or kitchen. 

Insects, Diseases, and Other Plant Problems:  Monitor for mealybugs, spider mites, and scale insects. Overwatering or poorly drained soil can cause root rot and other fungal issues. Browning of the tips of the fern can be caused by inadequate water or low humidity.
