At present, this plant is not yet available from any retailer. While it is still quite rare in the hobby, there are a growing number of hobbyists around the world that keep it. In time, it will become more widely available.
Not overly picky about the conditions under which it grows, it needs strong lighting, the addition of ample co2 and a well rounded fertilization routine to show the strong purple colors shown in this text's accompanying photograph. Limiting nitrate levels to around ten to fifteen part per million will help accomplish that. Additionally, a phosphate level of 1-2ppm should be maintained. It has a medium to fast growth rate under those parameters.
To accomplish propagation, one should top the stem with sharp scissors just above a pair of leaves, leaving about 3-4 inches of stem planted in the substrate. This will encourage new sides shoots to form. As with any other stem plant the tops can then also be replanted to form new plants. Emersed culture is nearly trouble free and results in much faster - and often much larger - growth. The easiest way to obtain emersed stems with this plant is to simply let stems grow out of the water. When emersed stems are topped and replanted, the tops frequently respond with a small degree of wilting, from which they may take several days to recover. A spacious enclosure combined with no unnecessary trimming and elevated humidity help to mitigate that problem.
Due to its striking coloration, Hyptis lorentziana is best used as an accent plant in the backdrop of an aquascape. The large purple leaves make an excellent contrast to the many finer-leaved green plants that are available in the hobby
