Plant Profile Myriophyllum Tuberculatum is a striking and highly sought-after aquatic stem plant famous for its fine, needle-like foliage that radiates out in delicate, fir-like whorls along sturdy central stems that deliver exceptional visual texture and dynamic color. Under high-tech aquarium conditions, its foliage displays a fiery spectrum of rusty orange, salmon, and deep copper-red. Reaching 6 to 12+ inches in height, Myriophyllum Tuberculatum serves as a spectacular centerpiece or high-contrast background in Dutch-style layouts and nature aquariums. *Form Notice: Photos display this plant in both its emersed (above-water) and submerged forms. Depending on nursery availability and seasonality, you may receive this plant in either form. Learn more about what to expect by reading our guide on Emersed vs. Submerged-Grown Aquatic Plants. Key Features & Benefits Delicate, needle-like feathery whorls create a stunning pine-like texture and soft motion in background zones. Displays a fiery spectrum of bright orange, copper, and rusty red foliage under high lighting and nutrient-rich conditions. Fast-growing stem habit acts as a natural nutrient sponge, helping absorb excess nitrates when grown under strong light. Care & Planting Instructions Remove lead weight (or pot) and remove cotton wrap (or foam) surrounding the roots, then strip lower foliage so bare stems anchor cleanly into soil without rotting. *Myriophyllum stems and leaves are extraordinarily thin and delicate, so handle with extreme care during preparation. Use fine-tip pinsettes to push individual stems 1 to 2 inches into substrate, spacing them slightly apart so light reaches lower foliage and prevents leggy decay. Provide high-intensity lighting and soft, acidic water (pH 5.0–7.0); mandatory pressurized CO2 injection alongside balanced macronutrients (nitrates 5–15 mg/L, phosphates 1–2 mg/L) and regular liquid iron dosing are essential to maintain needle density and prevent stunted growth. See our guide to growing red aquarium plants. Maintain stable water parameters and avoid sudden environmental shifts to prevent leaf melt or needle shedding. Trim main stem tops with sharp straight scissors once stems reach the desired height, and replant lateral shoots or top trimmings directly into substrate to propagate and expand your bush.

Why are the lower leaves falling off my stem plants? Lower leaf loss (leggy stems) usually occurs when lighting cannot reach the bottom of the plant due to overcrowding or shading from larger plants. Spacing individual stems slightly apart during initial planting and maintaining strong light penetration will keep lower foliage healthy. 2. How do I achieve the vivid red and orange colors on Myriophyllum Tuberculatum? Achieving bright orange and red coloration on Red Watermilfoil requires high-intensity lighting, high levels of injected CO2, nutrient-dense aquasoil, and consistent fertilization. Maintaining nitrates between 5–15 mg/L, phosphates between 1–2 mg/L, and regularly supplementing with liquid iron will prevent stunting and dull coloration. 3. How do I transition Myriophyllum Tuberculatum from emersed to submerged growth? When transitioning from emersed to submerged growth, plant bare stems securely into rich substrate under strong lighting and high CO2 while keeping water parameters stable. As new growth adapts, the plant will shed its stiffer emersed leaves and sprout soft, feathery red underwater needles. Once new shoots take root, trim away old lower growth to encourage dense branching.
