Ammannia capitellata

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Best suited for the midground or background due to its robust size. Grouping several stems together creates a striking focal point. Ensure it receives unshaded, direct light to maximize its color potential.

Botanical form

Stem

Features thick, fleshy stems and slightly wavy, lanceolate leaves. Under optimal conditions, the foliage develops stunning hues ranging from warm orange to deep crimson. Its robust architecture provides strong vertical lines in the aquascape.

Growth

Medium

Grows at a moderate rate, slightly slower than many other stem plants. This manageable growth makes it easier to maintain in a designated area. High light and CO2 injection will significantly accelerate its upward growth.

Substrate

Medium

Ammannia capitellata develops a moderately robust root system that benefits from a nutrient-rich substrate. A fine-grained aquasoil or a laterite-based gravel provides an ideal foundation, allowing the roots to penetrate easily and establish a secure anchor. A substrate depth of at least 4 to 5 centimeters is recommended to support its vertical growth and prevent uprooting. While it can absorb nutrients from the water column, root uptake is significant, making root tabs a valuable addition in older substrates.

Column fertilization

Recommended

Highly benefits from consistent water column dosing of both micro and macronutrients. Potassium and iron are particularly important for leaf health and vibrant coloration. Liquid fertilizers should be applied regularly to keep the water nutrient-rich.

Root fertilization

Optional

Thrives with a nutrient-rich substrate or the addition of root tabs. Strong root systems develop when the substrate is fertile, leading to thicker, healthier stems. A soil-based substrate is highly recommended over inert gravel.

Trimming

Occasional

Prune by topping the stems and replanting the healthy tops. The remaining lower portions will eventually sprout new side shoots if they are not too shaded. Remove any decaying lower leaves to maintain water quality and aesthetic appeal.

Propagation

Cuttings

Easily propagated through stem cuttings. Snip a healthy top portion and insert it directly into the substrate. The cutting will quickly develop new roots and continue growing towards the light.

Sensitivity

Moderate

Prone to lower leaf drop if shadowed by other plants or if nutrients are lacking. It can be sensitive to sudden changes in water parameters, leading to melting. Requires stable, soft to medium-hard water for the best results.

Layout role

Midground, Background

Serves as an excellent focal point or contrasting background plant. Its warm tones break up the monotony of green plants in a Dutch or nature-style aquascape. The thick stems add substantial texture and visual weight.
