Alternanthera reineckii I have grown this plant many times in aquariums as a submerged aquatic plant. It makes a beautiful bright pink to dark maroon plant. While in Singapore I visited a friend who had it growing in his nursery like a weed and I have to say it was an eye catcher to see grown out of water. The piece I have here came from that trip and it has been easy to grow and propagate so I am offering up plants. Could be used in aquariums small containers or in a terrarium to wabi-kusa setting. Hardy zone 10 up.
