Description

Native to Africa, spikemoss is a cousin to the true ferns, a low growing, mat-forming vascular plant. Unlike other moss, it has a more traditional root structure.  It can sprout roots from its stems.

In the tropics, it is planted it in the shade in rich, moist to wet soils.  The dense mat it forms makes it an option as a lawn alternative or use it in a rock or woodland garden that gets shade.  It tolerates light foot traffic and is resistant to rabbit browsing.  Propagate it by division or rooting stem cuttings in damp soil.

It makes a great houseplant, container plant, dish gardens or used in terrariums.  High humidity and indirect lighting are a must in order for your plant to flourish, with tropical conditions being ideal.  Humidity can be raised by placing between other plants, misting, or in the case of indoor, container use, place in your bathroom.  

Trimming back will control the rapid spread of this plant.  Retain the cuttings, as they will root easily.  

Its roots are shallow, so it can be planted in shallow pots.  

Watering should be done with room temperature water as cold water can shock the plant.

Insects, Diseases, and Other Plant Problems:  Direct sunlight will scorch the foliage.  Dry air will lead to brown or shriveled foliage.  

Allowing the plant to remain wet can lead to root rot.  Provide good drainage.
