Ammannia Praetermissa care guide
Ammannia Praetermissa (Ammannia praetermissa) — high light, 22-28 °C, pH 5.5-7, CO2 recommended.
Overview
Ammannia Praetermissa (Ammannia praetermissa) is an aquatic plant of the family Lythraceae, listed in the Aquairi knowledge base as an advanced-level species. It is typically grown under high light with pressurised CO2 injection on any substrate. Compact rosette-forming Ammannia with reddish leaves and short internodes. Grows slowly into bushy clumps in the foreground/midground; demanding for color but rewarding.
Taxonomy
- Family: Lythraceae
- Genus: Ammannia
- Scientific name: Ammannia praetermissa
Habitat
Ammannia is a genus of marsh stem plants (Lythraceae) of warm wetlands and rice paddies in Asia, Africa and the Americas; submersed forms develop red to orange foliage under strong light. In the Aquairi knowledge base, populations associated with this form are recorded from Africa.
Growth requirements
- Lighting: high
- CO2: recommended
- Temperature: 22-28 °C (72-82 °F)
- pH: 5.5-7
- GH: 2-10 °dGH
- Substrate: aquasoil
- Maximum height: 15 cm
- Growth rate: medium
- Recommended placement: midground
Placement
A midground-to-background stem grown in groups; intense light, CO2 and adequate nutrients deepen the red tones, while shaded growth stays green. In the Aquairi knowledge base this form is recommended for the midground under high light with pressurised CO2 injection, using undefined.
Propagation
Propagated by cuttings, with side shoots forming below the cut point; lateral shoots can be detached and replanted. Documented propagation techniques for this entry include: stem cuttings.
Common issues
Lower leaves drop in dense or shaded stands, and pale new growth signals micro-nutrient deficiency; strong light and balanced dosing maintain colour.
