Hydrocotyle Tripartita Japan is the popular name of the plant in different plant forums. It is a variant of Hydrocotyle Tripartita from South-East Asia. It is characterised by fast, compact growth and small, intense green leaves on vertical stems. The plant is carpet-forming (5-10cm tall) and its compact growth can be promoted by physically pressing the carpet with your hand when maintaining your aquarium (mechanical retardation). Carpet formation and compact growth do best in good light. Tropica 1-2-Grow Tissue Culture PlantsSmall plants with great success.
