Utricularia Graminifolia care guide
Utricularia Graminifolia (Utricularia graminifolia) — high light, 20-26 °C, pH 5.5-7, CO2 recommended.
Compiled by Aquairi from published sources · Published · Updated
Overview
Utricularia Graminifolia (Utricularia graminifolia) is an aquatic plant of the family Lentibulariaceae, listed in the Aquairi knowledge base as an advanced-level species. It is typically grown under high light with pressurised CO2 injection on nutrient-rich aquasoil. A carnivorous grass-like plant that forms a stunning bright-green carpet of tiny narrow leaves. One of the most demanding carpet plants, requiring CO2, high light, and meticulous care, but the result is an unparalleled lush lawn.
Taxonomy
- Family: Lentibulariaceae
- Genus: Utricularia
- Scientific name: Utricularia graminifolia
- Common synonyms: UG
Habitat
Utricularia graminifolia is a small carnivorous plant of the family Lentibulariaceae from southern Asia; in nature it grows in shallow, soft, acidic waters and uses minute bladder traps to capture micro-fauna. In the Aquairi knowledge base, populations associated with this form are recorded from Southeast Asia.
Growth requirements
- Lighting: high
- CO2: recommended
- Temperature: 20-26 °C (68-79 °F)
- pH: 5.5-7
- GH: 1-8 °dGH
- Substrate: nutrient-rich aquasoil
- Maximum height: 4 cm
- Growth rate: slow
- Recommended placement: foreground carpet
Placement
Foreground carpet; the fine grass-like leaves create a tight low lawn, but acclimation can take several weeks of slow growth. In the Aquairi knowledge base this form is recommended for the foreground as a carpet under high light with pressurised CO2 injection, using nutrient-rich aquasoil.
Propagation
Spreads laterally through fine runners; healthy patches can be separated and replanted into new areas. Documented propagation techniques for this entry include: horizontal runners.
Common issues
Sensitive to algae and disturbance during establishment; stable parameters, soft water, CO2 and high light support reliable carpeting.
Propagating Utricularia graminifolia (UG)
Overview
Utricularia graminifolia is a small perennial carnivorous plant in the family Lentibulariaceae, native to Asia (Burma, China, India, Sri Lanka and Thailand). In nature it grows as a terrestrial or affixed subaquatic plant in wet soils and marshes and is not a true aquatic species, yet it is cultivated in planted aquaria as a bright-green carpet. It spreads as a mat of fine, grass-like leaves on creeping runners (stolons) rather than from a single root system.
Propagation Method
UG is propagated by dividing the mat. Because it grows from horizontal runners spreading across the substrate, the way to multiply or divide it is to cut these runners and lift small clumps, then replant them elsewhere. The same action is used both to thin established growth and to start new patches.
Step-by-Step
- Dip your scissors into the substrate and cut the runners beneath a section of the mat.
- Lift the freed clump together with its leaves and runners.
- Divide it into small clumps sized for the gaps you want to fill.
- Press each clump gently into the substrate so the runners stay in contact with it.
- Remove any loose leaves and runner offcuts completely so little organic material is left to decompose.
Conditions for Healthy Growth
UG is demanding and takes a while to acclimatise, but once settled it grows quite rapidly. CO2 injection significantly improves both acclimatisation and propagation rates, and dosing fertilisers further improves how fast it spreads. Pair this with high light and stable, soft water for the best carpet.
Maintenance
Trim by dipping the scissors into the substrate and cutting the runners, then remove the connected leaves and runners completely so minimal organic material is left to decompose. Over time its runners will loosely adhere to coarse hardscape such as lava rock, which helps anchor and extend the carpet.
Common Challenges
- Melting after transplant, especially if planted into fresh, uncycled soil.
- A slow start, since the plant takes time to acclimatise before it spreads quickly.
- Decaying offcuts fouling the substrate if trimmed leaves and runners are not removed completely.
