Also called the Cretan brake or silver lace fern, Pteris cretica sends up airy, ribbon-like fronds, often with a pale silver-white stripe down the centre, for a light, feathery texture in a terrarium.
Light
Bright, indirect light keeps the variegation crisp; too little light and the silver markings fade to plain green. Keep it out of direct sun.
Water & humidity
Keep the substrate evenly moist. Like most brake ferns it dislikes drying out but also resents soggy roots, so a free-draining mix that still holds moisture is ideal.
In the terrarium
A graceful filler for medium and larger terrariums. It's more forgiving than most ferns, but it can reach around 30 cm, so give it room or plan to trim and eventually move it on as it matures.
Origin & temperature
The Cretan brake fern grows wild across a huge range of the Old World, southern Europe, Africa and Asia, in shaded, rocky and woodland habitats, which is why it tolerates a wider range of conditions than most tropical ferns.
Temperature: comfortable at 16–24 °C and tolerant of cooler spells. Pet safety: non-toxic to cats and dogs.
Propagation
Divide the clump at the base, keeping roots and a few fronds on each piece, and pot straight into damp mix. It also self-sows readily from spores in a humid terrarium, sometimes appearing uninvited on nearby surfaces.
Common problems
- Fading silver markings = not enough light; move somewhere brighter (still indirect).
- Brown, dry fronds = it dried out; keep the mix consistently moist.
Good companions
Silver Ribbon Fern 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
Does the Silver Ribbon Fern suit a closed terrarium?
Yes, while young, it loves the humidity. Just note it can reach about 30 cm, so in a small sealed jar you'll be trimming it or rehoming it in time.
Why has my fern lost its silver stripe?
Low light. The variegation needs bright, indirect light to stay pronounced; in shade it reverts toward plain green.
