Plant Profile Ammania Gracilis is a graceful and large-statured aquatic stem plant native to the tropical riverbanks and wetlands of West Africa. Celebrated for its opposing, wavy-edged leaves that arch elegantly from sturdy central stems, this species is highly valued for bringing warm sunset hues to planted tanks. Depending on light levels and nutrient availability, its foliage displays a stunning spectrum ranging from pale olive-green to blushing pink, salmon, and deep copper-red. Reaching 5 to 8+ inches in height, Ammania Gracilis makes an extraordinary midground centerpiece or background accent when contrasted against bright green foliage. *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 Elegantly arching, wavy-edged leaves display a vibrant blend of blushing pink, salmon, and deep copper-red. Versatile in submerged aquariums, open-top paludariums, and bog gardens, blooms purple flowers emersed. 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. Use fine-tip pinsettes to push individual stems 1 to 2 inches into substrate, spacing them slightly apart so high light reaches lower leaves and prevents leaf shedding. Provide high-intensity lighting. Pressurized CO2 injection (25–30 ppm) alongside elevated phosphates, rich micronutrients/iron, and lean nitrates will yield the most vibrant pink and red leaf coloration. See our guide to growing red aquarium plants. Maintain stable water parameters and avoid sudden environmental shifts to prevent leaf melt or stem rotting. Trim main stem tops with straight scissors once stems reach the desired height, and replant trimmings directly into substrate to propagate and expand coverage. Read our trimming & propagation guide for details. Quick Facts Listed information should be treated as general guidelines only.

Attribute Specification Scientific Name Ammannia gracilis Common Name(s) Ammannia gracilis, Large Ammania, Red/Pink Ammania, Delicate Ammania Family Lythraceae Plant Type / Taxonomy Stem Plant Care Difficulty Medium to Difficult Light Requirement High (Essential to prevent bottom leaf loss) CO2 Requirement Recommended (25–30 ppm yields best health and color) Placement / Usage Midground / Background Accent Height / Size 5–8”+ Growth Rate Fast Water Parameters pH 5.0–7.5 (Soft, acidic water preferred) Propagation Method Cuttings (Cut stem tops or lateral shoots and replant) Origin West Africa Frequently Asked Questions 1. 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 leaves healthy. 2. How do I bring out the blush-pink and red colors on Ammania Gracilis? Achieving vibrant pink and red foliage on Ammania Gracilis requires high-intensity lighting, pressurized CO2 (25–30 ppm), soft acidic water, and consistent dosing of liquid micronutrients and iron. Maintaining lower nitrate levels alongside elevated phosphates also encourages deeper color saturation. 3. How do I transition Ammania Gracilis from emersed to submerged growth? When transitioning from emersed to submerged growth, plant bare stems securely into rich substrate under good lighting and keep water parameters stable. As new growth adapts, the plant will shed its stiffer emersed foliage and sprout soft, wavy-edged underwater leaves with reddish-pink highlights. Once new shoots take root, trim away old lower growth to encourage dense branching.
