  • stem
Botanical name [?]: Ammánnia crassicáulis Guill. & Perr.

Major group (unranked): Seed plants: Flowering plants (Angiosperms)
Order: Myrtales
Family: Lythraceae
Genus: Ammannia


The up to 50 cm high bog plant Ammannia crassicaulis, known in the hobby as Nesaea crassicaulis, is distributed in swamps, rice paddies and rivulets of the African and Madagascan tropics.

It is often confused with Ammannia gracilis, which indeed looks very similar, however, in the aquarium it has less intensively red hues, but is rather of a yellowish green to pale red. Most plants in trade that are sold under the name N. crassicaulis really are Ammannia gracilis. (It is possible that even the photo of this database entry shows A. gracilis.)

Wasserpflanzen sind ein fester Bestandteil der meisten Aquarien. Beim Aquascaping, dem Naturaquarium, Biotop-Aquarium oder dem Gesellschaftsaquarium sind Wasserpflanzen nicht nur für die Wasserqualität entscheidend, sondern sorgen auch stets für eine optische Aufwertung des Aquariums.
