Small-leaf Spiderwort is a fast, forgiving trailer of glossy oval leaves (often striped cream or flushed purple beneath), one of the easiest plants you can add to a terrarium.
Light
Bright, indirect light keeps growth compact and any variegation strong; in low light it stretches and greens up. A little gentle sun is fine.
Water & humidity
Keep the substrate evenly moist. It's very forgiving either way and roots almost instantly from any trimmed piece.
In the terrarium
A reliable filler and trailer that grows quickly, which is both its strength and its catch. Trim it often, as it can smother slower plants; note it's an environmental weed in some regions, so never discard cuttings outdoors.
Origin & temperature
Tradescantia fluminensis originates in southeastern Brazil and has become a notorious environmental weed in warmer regions, so cuttings should never be discarded outdoors.
Temperature: 15–25 °C. Pet safety: the sap can irritate the skin of people and pets, so handle with a little care.
Propagation
About as easy as propagation gets: lay any stem cutting on damp substrate and it roots within days.
Common problems
- Leggy, pale growth = too little light; move it brighter.
- Taking over the terrarium = its natural vigour; prune regularly to keep it contained.
Good companions
Small-leaf Spiderwort 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:
