Persicaria maculosa (Sao Paolo)

*Pictures are of the plant at full potential*

One of the most beautifully coloured aquarium plants. Under good lights and with an ample nutrient supply, Persicaria sp. "Sao Paulo" assumes intensive magenta tones when cultivated under water. The stems have a strictly upright growth habit. If you don't trim it the plant will grow out of the water and start to flower. The emersed foliage is rather medium to dark green.
As with as all Persicarias, this plant has a relatively high demand for macro- and micronutrients that are also taken up from the substrate. CO₂ addition is recommendable. Rather strong lighting enhances its striking coloration. Its shoots are best planted in a group with a bit of space to each other. As well as other stem plants, it is propagated by cuttings.

It will grow with lesser light and co2 but you will not get the colours. 

This strikingly coloured stem plant is most effective when planted as a loose free-standing group in the midground. It contrasts well with light green plants. Persicaria sp. "Sao Paulo" is also interesting as emersed plant for open aquariums, paludariums and Wabi-Kusa.
