Ammannia senegalensis, also known as copper leaf ammania, is a flowering plant native to western Senegal, often growing as a weed in rice paddies.
The stem presents opposite leaves that start out green and rather broad and, later, become more narrow and reddish in colour. The leaves especially become red under intense light. There are several varieties, of unknown status, that differ in leaf shape and colour.
The flowers are inconspicuous, growing from the leaf axils of emersed plants.
These plants prefer intense light for optimum growth. They can grow quickly in the right conditions and will grow in flooded conditions, if the water is shallow enough. They also grow very well with additional carbon dioxide added to the water. Ideal water conditions are soft and acidic, but these plants are generally hardy and adaptable in most moderate conditions. To grow well, they need a good iron micronutrient to be added to an aquarium.
They can be easily propagated by pushing cuttings into the substrate.

Ammannia senegalensis, con el nombre común de "copper leaf ammania", es una planta acuática perteneciente a la familia Lythraceae. Es originaria del oeste de Senegal, a menudo creciendo como una mala hierba en los arrozales.
Es una planta herbácea erecta o postrada que alcanza los 4-35 cm de alto; los tallos son tetrangulares. La especie tiene hojas estrechas, onduladas y opuestas.

Se encuentra en el suelo húmedo de agua dulce de temporada, en el césped corto y juncias, en esteros sobre suelos arenosos, en el limo de arena húmeda a la orilla de las lagunas a una altura de 0-450 metros. Distribuyéndose por Egipto, Sudáfrica, Namibia, Suazilandia y Botsuana.
Estas plantas prefieren una gran cantidad de luz para un crecimiento óptimo. Pueden crecer rápidamente en las condiciones adecuadas y crecerá sobre el agua, si es poco profunda. Crecen mejor con dióxido de carbono añadido al agua. Las condiciones ideales del agua son suaves y ácidas, pero estas plantas son generalmente resistentes y adaptables en la mayoría de las condiciones moderadas. Para crecer así que necesitan micronutrientes de hierro añadido al acuario.
Pueden ser fácilmente reproducida por estacas en un sustrato.
