Though it looks like a lush, feathery moss Spikemoss is actually a primitive fern ally. It forms a soft, spreading emerald carpet and demands the high humidity a closed terrarium provides.
Light
Bright, indirect light. It scorches in direct sun and thins out in deep shade.
Water & humidity
Must stay constantly moist, Spikemoss crisps up rapidly if it dries, and unlike true moss it rarely recovers from a full dry-out.
In the terrarium
A superb carpeting plant for closed terrariums, where the sealed humidity keeps it plush. The golden 'Aurea' form adds a bright chartreuse groundcover.
Propagation
Selaginella spreads readily from division or even loose stem fragments, pieces will root wherever they rest against damp substrate. Scatter short lengths across the surface, keep them moist, and they knit into a carpet.
Common problems
- Browning, crispy fronds = it dried out or humidity dropped.
- Pale, sparse growth = too much light or too little humidity.
Good companions
Spikemoss pairs well with plants that want the same conditions, a humid, closed terrarium with bright, indirect light. Here are some species that thrive alongside it:

Frequently asked questions
Is Spikemoss a real moss?
No, despite the name and mossy look, it's a spikemoss (a fern ally). It needs the same high humidity as moss, though.
Does Spikemoss need a closed terrarium?
Effectively yes, it needs constant high humidity, which a sealed closed terrarium supplies far better than open air.
