This plant is propagated by cuttings. When the mother plant is pruned back keep the cuttings and strip off the bottom leaves to leave an inch of bare stem. Carefully place the cuttings into the substrate ensuring that the stem does not get crushed and roots will appear in a short time, at the first node.
This plant is very demanding and requires lots of lighting plus a lot of nutrients in the water for it to keep its stunning red colouration. A CO2 system and soft, acidic water must be used and the stems should not be planted too close together or the bottom leaves will die off due to lack of light.
