Since I added the two small Pogostemon erectus cuttings to this aquarium, the parent plant in my larger display aquarium has done poorly. I think this is in part because of the lower light at 0.6 wpg (the plant growth stagnated), and that the plecos and snails have taken to it as dinner.
I have now moved all the remains of the plant to the back, right corner of this aquarium, the area where the Rotala rotundifolia was originally meant to go. They seem to be settling in. Although growth is slow, new stems and buds are growing consistently along all the stems.
The drawing is by Kirsten Tind. It is of a style known as botanical illustration, which are traditionally printed along side descriptions of the plants. This particular drawing was commissioned by Tropica Aquarium Plants and looks very similar to how my Pogostemon erectus cutting looked when it arrived in July.
