Rotala verticillaris is one of the newer Rotala species entering the hobby from Asia, which coincidentally is also one of the prettiest plants coming in as of late. Believe it or not, but Rotala verticillaris is actually the reference species for the Rotala genus. It’s amazing how diverse this particular group of plants can be when compared to the more common Rotala rotundifolia or some of the other more delicate species. Rotala verticillaris has a thicker stem and branches very tightly, but unlike some others it grows nearly vertical, which make stands of the plant extremely orderly and well positioned.
Also different about Rotala verticillaris is its flower, which resembles something more of a Pogostemon species, than some of the other Rotalas. The flower is, however, quite beautiful exhibiting a striking purple with featherly fronds coming off. Below is a picture of my friend Cavan’s flowering plant.
In the aquarium, Rotala verticillaris is not as undemanding as Rotala rotundifolia, as it should require medium/high light plus CO2 injection. Of course, like all plants, it will benefit greatly from a rich substrate and addition fertilization. It is also not as fast a grower as other Rotala species, which in my opinion is a positive thing. I highly recommend this plant for use in any style of aquascape, but it is more perfectly suited to aquascapes with fine leafed and well manicured background stem plants.
