The stem plant Bacopa australis has only recently become available to buy. We found this verdant beauty on our Plantahunter tour in Brazil in 2010. At the source of the Rio Sucuri, we discovered some gorgeous specimens living in crystal clear water alongside other aquarium plants. This plant is very easy to cultivate. When emersed, the leaves are smaller and fleshier, whereas in aquaria they are very fragile and thin. We recommend regular pruning to create a compact group of plants.
