Pogostemon erectus, a species from India, differs very much from the standard Pogostemon species in the aquarium hobby. This plant was erroneously imported as Rotala verticillaris, and later on correctly identified by means of its flowers.

The light green needle-like narrow leaves grow densely on the stems. The plant is especially beautiful when planted in dense groups in the middle or background.

When provided with good light (at least 0.5 W/litre), the addition of CO₂ and regular fertilisation, this Pogostemon is not especially difficult in cultivation.

Notes:

• If received in a pot, please remove all rock wool from the roots. Where possible we try and ship without pots or rockwool. Due to them being non-biodegradable we prefer to propagate in an environmentally conscious way.
• CO2 will generally yield better growth rates.
• Stable water conditions are a must, changes should occur over a period of time in order to reduce chances of melting etc.
