Hydrocotyle Japan - Hydrocotyle Tripartita
Tripartita, commonly known as Hydrocotyle Japan, was made famous by Takashi Amano. He used this plant often in his aquascapes and did wonders with it in many planted tanks!
It is quite versatile and can be used as a foreground, midground or background plant. It is undemanding and grows fast, often out-competing and overgrowing the tank if left untrimmed. By frequently trimming new growth and using high light with CO2, the plant can stay low growing and create a carpeting effect over the foreground.
Propagate by trimming stems and replanting on pulling apart dense clumps and splitting the roots. New shoots can be trimmed anywhere along the stem which allows the plant to grow thicker and more compact.
Max size/height is about 5-10" or so.
