Description
One of the most beautifully coloured aquarium plants. This aquatic knotweed from Brazil probably belongs to Persicaria hydropiperoides that occurs from North to South America, but its species identity has not been confirmed yet. 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.
In trade, you usually get Persicaria sp. 'Kawagoeanum' under this name, however, we are proud to offer you the true, much more intensively coloured Persicaria sp. "Sao Paulo".
As well 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.
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.
Persicaria (Polygonum) sp. 'Sao Paulo' is a phantastic new aquarium plant from Brazil. At the moment, the correct species name of this knotweed is still in the dark. When kept in the right conditions, this is probably the most intensively coloured plant species currently avaiable for aquaria. It is offered by the Japanese company Rayon Vert, and it is also available among hobbyists in the USA.
Unfortunately, under the name Polygonum sp. 'Sao Paulo' there is also another plant in trade, namely the very similar P. sp. 'Kawagoeanum', and it is even questionable if true 'Sao Paulo' is available in Europe at the moment.
Thus we will list some characteristics suitable for differentiating these rather similar knotweeds in the following.

A embalagem in vitro que comprei não vinha em grandes condições e acabou toda de melar no aquário. Brevemente farei outra tentativa pois quero mesmo esta planta

The plant arrived in very good conditions and started growing immediately at good speed.
Totally worth, I am very happy with it!

Ich empfehle, wie immer, bin ich glücklich :)
