Acmella repens is a plant from the Asteraceae family growing in the southeast of the USA, from Texas to North Carolina, as well as in Central and South America, from Mexico to Paraguay1. This relatively small plant with its yellow flowers occurs in disturbed, wet or drying-out locations. It belongs to the same genus as the medical/spice plant paracress or jambú (Acmella oleracea).
Only a short time ago, aquaristis from the USA have discovered that Acmella repens, which they collected in Texas, can be cultivated submersed. Outside the USA it is hardly known as aquarium plant yet.
