Overview

Native to the tropical wetlands of Africa and Madagascar, this plant is also known as Nesaea crassicaulis. Its tones range from yellowish green to pale red. It looks very much like Ammannia gracilis, usually redder, and the two are often confused in the trade.

In the aquarium

Growing in the aquarium

It needs strong lighting and rather soft water, in a tank suited to demanding plants. Cuttings are used to fill out a group of stems. Check the identity of a plant bought as Nesaea: the source notes that many plants sold under that name are actually Ammannia gracilis.
