Its small, vibrant green, clover-like leaves give it a unique texture, which contrasts beautifully with finer-leaved or red plants. Although the 'Japan' cultivar is commonly traded, the species itself originates from areas spanning Australia, New Zealand, and Southeast Asia.\u003c\/p\u003e\n\u003cp\u003eThis plant is incredibly adaptable in its placement. It spreads quickly by sending out runners along the substrate or hardscape. When given high light and regular pruning, it stays low and forms a dense, lush carpet in the foreground. If left to grow, it can form thick, cascading bushes in the midground or trail elegantly over rocks and driftwood. Its rapid growth makes it an excellent plant for consuming excess nutrients, thereby helping to keep the water column clean and deterring algae outbreaks.\u003c\/p\u003e\n\u0026lt;\u0026gt;\n\u003ch4\u003eCare \u0026amp; Planting:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLighting:\u003c\/strong\u003e \u003cstrong\u003eMedium to High\u003c\/strong\u003e. While it tolerates medium light (where it grows taller and less dense), high light is essential for achieving the prized, short, and compact carpeting effect.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCO₂ Supplementation:\u003c\/strong\u003e \u003cstrong\u003eRecommended\u003c\/strong\u003e. CO₂ injection dramatically increases its growth speed and lateral branching, resulting in the desired bushy, dense appearance. Without it, growth is much slower, and the plant tends to be more sparse. Ideal CO₂ concentration is around 20−30 ppm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFertilization:\u003c\/strong\u003e Water Column and Root Feeder. Due to its fast growth rate, it is demanding of nutrients. It benefits significantly from a nutrient-rich substrate (aquasoil or root tabs) and consistent liquid fertilizer dosing. Yellowing leaves are often the first sign of nutrient deficiency, particularly a lack of micronutrients.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlanting:\u003c\/strong\u003e Runner\/Stem Plant. Separate the runners into small tufts, ensuring each piece has a few root nodes. Plant the clusters lightly into the substrate, allowing adequate spacing (about 1.5 inches) to allow the runners to fill in and form a carpet. It also attaches easily to rough surfaces like wood and rock.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePruning:\u003c\/strong\u003e Frequent. To maintain a low carpet or bushy shape, frequent trimming (every 1-2 weeks in a high-tech tank) is necessary. Trimming encourages the plant to branch out horizontally and thicken, while preventing it from completely overgrowing the aquascape. Cuttings can be easily replanted to expand the carpet.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u0026lt;\u0026gt;\n\u003ch3\u003eQuick Facts\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eScientific Name:\u003c\/strong\u003e Hydrocotyle tripartita (often sold as 'Japan')\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Common Name:\u003c\/strong\u003e Japanese Pennywort\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOther Common Names:\u003c\/strong\u003e Hydrocotyle 'Japan', Clover Plant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Australia, New Zealand, Southeast Asia\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Height:\u003c\/strong\u003e 2-10 inches (5−25 cm), depending on light\/CO₂\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowth Rate:\u003c\/strong\u003e Fast\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDifficulty:\u003c\/strong\u003e Easy to Moderate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCO₂:\u003c\/strong\u003e Recommended\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Temperature:\u003c\/strong\u003e 68\u003cspan\u003e° \u003c\/span\u003eto 82\u003cspan\u003e°\u003c\/span\u003eF (20\u003cspan\u003e° \u003c\/span\u003eto 28\u003cspan\u003e°\u003c\/span\u003eC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003epH Range:\u003c\/strong\u003e 6.0 - 7.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlacement:\u003c\/strong\u003e Foreground to Midground\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JBJ","offers":[{"title":"Each","offer_id":67705434800348,"sku":"yaz1791986574562","price":7.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0834\/1422\/1020\/files\/hydrocotyle-tripartita-japan---tissue-culture_1.webp?v=1791986580","url":"https:\/\/calmhemwear.shop\/products\/hydrocotyle-tripartita-japan-tissue-culture","provider":"My Store","version":"1.0","type":"link"}
