This knotweed was first introduced as Polygonum sp. 'Ruby' and later identified as Persicaria praetermissa ( = Polygonum praetermissum). This plant occurs in wide areas of tropical Asia and Australia, in marshy areas and on streamsides, and can grow above and below water. It has an interesting hastate leaf shape and develops nice reddish tones in its submerged forms. It is also an unusual stem plant due to its partly horizontal growth.

Persicaria praetermissa is not too difficult, however medium to strong lighting and a good nutrient and CO2 supply are beneficial. It grows rather fast and is easily propagated by cuttings.

With its unusual horizontal growth habit, conspicuous leaf shape and nice, rather dark colours, this knotweed species is best placed as an accent plant in the midground, contrasting to light green, finely textured plants. Persicaria praetermissa is also interesting as emersed plant for paludariums and Wabi-Kusa.

Please be aware that the submerse form of this plant could contain snails and other invertebrates.



Aquasabi is our own brand, under which we offer high-quality products with a very good price-performance ratio. Carefully selected CO2 diffusers, CO2 bubble counters or lily pipes are just some of the items we sell under this brand and which will surely add to the value und the beauty of any aquascape. For this reason, many aquascapers and planted tank enthusiasts use products by Aquasabi.

Besides the good price-performance ratio, our main focus is on the satisfaction of our customers. This is the reason why our doors are always open for those who need help with our products.

When it comes to special aquatic plants, water plants from Aquasabi are just the thing for you. We offer rarities from our own cultivating tanks or import them specifically. These plants are otherwise hard to come by, and most of them cannot be purchased from other shops. We have high quality standards, which make Aquasabi plants a good choice for aquascapers, planted tank enthusiasts and aquatic plant collectors who want to enrich their tanks with rare aquatic plants. Special mosses, particular stem plants, hard-to-come-by ferns or very rare forms of the genus Bucephalandra are only a few of the plants we are proud to offer.
