Plant Profile Nesaea Crassicaulis is a rare and rewarding aquatic stem plant native to tropical Africa and Madagascar, prized by experienced aquascapers for its bold, reddish-brown to burnt-orange, narrow leaves. When provided with high-tech aquarium conditions, it'll reward you with thick stems and vibrant foliage that creates a striking contrast against green and red aquatic plants alike. Reaching 6–12 inches in height, Nesaea Crassicaulis makes an extraordinary background focal point, bringing a rich, earthy color palette that's hard to find elsewhere. It's a must-have for hobbyists building high-contrast, color-rich planted tanks. *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 Bold reddish-brown and copper-orange narrow foliage provides a rare color contrast with traditional green and red stem plants. Densely leafed background species that easily branches into thick, colorful bushes through routine pruning and replanting. Care & Planting Instructions Remove lead weight and remove cotton wrap (or foam) surrounding the base, then strip the lower inch of 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 light reaches lower growth. Provide high-intensity lighting and pressurized CO2 injection; maintaining soft, slightly acidic water with regular iron dosing accelerates growth and yields maximum reddish-brown 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 stem tops with straight scissors once they reach the desired height to encourage dense side branching, and replant trimmings directly into soil to propagate. Read our trimming & propagation guide for details. Quick Facts Listed information should be treated as general guidelines only.

Attribute Specification Scientific Name Nesaea crassicaulis Common Name(s) Nesaea Crassicaulis Family Lythraceae Plant Type / Taxonomy Stem Plant Care Difficulty Medium to Advanced Light Requirement Moderate to High CO2 Requirement Recommended (Essential for rich reddish-brown colors) Placement / Usage Background / Midground Bushing Height / Size 6–12”+ Growth Rate Fast Water Parameters pH 6.0–7.0 | Prefers Soft Water Propagation Method Cuttings (Cut stem and replant tops) Origin Africa / Madagascar 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 get my Nesaea Crassicaulis to turn deep reddish-brown? Achieving the rich, deep reddish-brown hues requires strong LED lighting, pressurized CO2 injection, soft water conditions, and consistent micronutrient dosing with liquid iron. Soil-based substrates that lower pH also help optimize nutrient uptake. 3. How do I transition Nesaea Crassicaulis from emersed to submerged growth? When transitioning from emersed to submerged growth, plant bare stems securely into rich substrate under high lighting and keep water parameters stable. As new growth adapts, the plant will shed its firmer land leaves and sprout delicate, reddish-brown submerged foliage. Once new shoots develop, trim away old lower growth to encourage dense branching.
