Ammannia gracilis

Ammannia gracilis is a plant in the family Lythraceae, also known by the common names large ammannia, red ammannia, pink ammannia, and delicate ammania, and is native to West Africa.
Stem plants have narrow, rather wavy leaves, growing opposite on an often robust stem. Depending on the light intensity, the leaves vary from a pale green to a bronzy red colour. They grow to about 5–8 inches (12–20 cm) or longer.
The flowers are inconspicuous, growing from the leaf axils of emerse plants.

Cultivation

These plants prefer much light for optimum growth. They can grow quickly in the right conditions and will grow emerse if the water is shallow enough. They grow well with additional carbon dioxide added to 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 added to the aquarium.

They can be easily propagated by cuttings pushed into the substrate.
