Microsorum pustulatum, also known as Hound's Tongue and Kowaowao, is native to Australia and New Zealand, and common in our coastal and montane areas. It is also common on all the three main islands, subantarctic islands, and on the Chatham islands. It is often epiphytic (growing on trees) usually in slightly drier areas. The glossy green fronds which vary in shape, are uncut and strapped in young plants, and once-cut on mature plants. They spread by fragmentation of the green and brown large, hairy rhizomes. Hound's Tongue Fern coming from the likened shape of a dog's tongue.

I mostly water it once a week. Under drifting shade in a pot. I bring it into the garage in winter. Lizards love to hide in it; when I water it they come scrambling out. Zone 9a, NE Florida

I've had one of these living outside for about 18 months now. Our temps dip down into the 20's & sometimes the teens but do not remain there for more than several hours. This plant did very well.

This spring I divided it into 4 parts - one going back into the hanging basket which gets a good dose of afternoon sun. It has already outgrown the basket. I'm hoping I won't have to divide it again until the spring.

The other sections were planted into a chunk of hollow oak along with some bromeliads in an area that doesn't get as much sun & they have not done as well.

This fern is a climber of the wetter forests in South-Eastern Australia, often climbing on the stems of Soft Tree Ferns, Dicksonia antarctica. It's name of Kangaroo Fern, refers to the shape of the fronds. On a young plant, the fronds are unbranched, but eventually develop multiple broad pinnae. There is an intermediate stage, where some of the fronds have a single branch pinna on one side only. This frond shape then resembles a kangaroo's footprint, which has one long toe and one slighly shorter toe beside it. I pegged a piece of Kangaroo Fern, to the stem of my Soft Tree Fern some years ago, and it has thrived there ever since, now wrapping itself several times round the tree fern stem, and regularly producing spores, although no new plants have arisen. I water the tree fern stem in summ... read more
