Limnophila Rugosa care guide
Limnophila Rugosa (Limnophila rugosa) — medium light, 22-28 °C, pH 6-7.5, no CO2.
Compiled by Aquairi from published sources · Published · Updated
Overview
Limnophila Rugosa (Limnophila rugosa) is a broad-leaved plant of the family Plantaginaceae, grown as an aquarium plant. Large stem plant with broad, deeply wrinkled leaves and a pleasant scent (when grown emersed). Tolerates low-tech tanks but does best with rich substrate and moderate light.
Taxonomy
- Family: Plantaginaceae
- Genus: Limnophila
- Scientific name: Limnophila rugosa
- Common synonyms: Wrinkled Limnophila
Habitat
Limnophila is a genus of marsh stem plants from tropical Asia and Africa, common in rice paddies and slow waters, with finely divided submersed foliage and broader emersed leaves. In the Aquairi knowledge base this species is recorded from Asia.
Growth requirements
- Lighting: medium
- CO2: not required
- Temperature: 22-28 °C (72-82 °F)
- pH: 6-7.5
- GH: 3-12 °dGH
- Substrate: nutrient-rich aquasoil
- Maximum height: 50 cm
- Growth rate: medium
- Nutrient demand: medium
- Recommended placement: background
- Typical trim interval: 14 days
Placement
In aquascapes this plant suits the background. It is a feathery background stem plant grown in groups; bright light and CO2 keep the whorls dense, while low light leaves it sparse and elongated.
Propagation
This species is propagated by cuttings; replanted tops root quickly and the genus branches freely from the cut stem.
Common issues
The fine foliage traps debris and is prone to algae if flow or maintenance is poor; insufficient light causes thin, widely spaced whorls.
Propagating Limnophila rugosa from Cuttings
Overview
Limnophila rugosa is a large, robust stem plant of the genus Limnophila, family Plantaginaceae. Members of the genus are annual or perennial herbs of wet, marshy habitats, some aquatic, native across tropical Asia and known as marshweeds. Several Limnophila are glandular and aromatic, and L. rugosa carries this fragrant, broad, wrinkled-leaved character, especially when grown emersed.
Propagation Method (Cuttings)
L. rugosa is propagated like other Limnophila stem plants: by cuttings. Topping a tall stem yields a replantable growing tip, while the base branches from lower nodes into new shoots. The species' vigour makes cuttings establish readily, whether the parent was raised submersed or emersed.
Step-by-Step
- Select a strong stem and cut the top 5-10 cm with clean scissors.
- Remove the lowest leaves so the bare stem can be planted without rotting.
- Set the cutting into rich, nutrient-dense substrate at the back of the layout.
- Leave the rooted base to push side shoots from its lower nodes.
- Space the broad-leaved stems so each receives adequate light.
Conditions for Healthy Growth
L. rugosa is a forgiving, robust grower that tolerates low-tech tanks but does best with a rich substrate and moderate light. The genus naturally thrives in warm, flooded, fertile ground, so steady tropical temperatures and good nutrition produce the largest, most vigorous broad leaves. CO2 is not strictly required but supports faster, denser growth.
Trimming & Maintenance
Because it grows tall, trim it back periodically and replant the tops to control height and keep stems leafy from the base. In Limnophila the submerged leaf form is less rigid and larger than the emersed form, so emersed-grown stems convert to their softer underwater leaves over a few weeks once planted in the tank.
Common Challenges
Leggy growth and bare lower stems usually mean too little light or crowding rather than a propagation issue; thin the group and replant fresh tops. Emersed plants of the genus tend to die back after flowering, so keep aquarium stock vegetative and submerged. As a potentially invasive marshweed, never release trimmings into natural waterways.
