Sarawak, Malaysia
One of the best terrarium Begonias for its cultural demand and its showy pattern. This one requires high humidity and moisture at the roots but does not like constantly wet leaves. A humid but not wet terrariums suits it best.
Plants available are rooted cuttings established in sphagnum. Actual attached plant photos are representative of currently available plants. I find in the rooting process of this species cuttings tend to suffer until they begin to form roots. That's why you see damaged leaf edges and why they're rumored to be so "sensitive to shipping". Plants will be shipped fully rooted and past that sensitive stage. I'd expect new leaves to be much nicer.
