Hygrophila Lancea Araguaia care guide
Hygrophila Lancea Araguaia (Hygrophila lancea 'Araguaia') — high light, 22-28 °C, pH 5.5-7, CO2 recommended.
Compiled by Aquairi from published sources · Published · Updated
Overview
Hygrophila Lancea Araguaia (Hygrophila lancea 'Araguaia') is an aquatic plant of the family Acanthaceae, listed in the Aquairi knowledge base as an intermediate-level species. It is typically grown under high light with pressurised CO2 injection on nutrient-rich aquasoil. A compact stem plant with narrow lanceolate leaves that develop rich coppery-red to orange coloration under high light with CO2. Its tight growth habit and warm colors make it an excellent accent plant for the midground of nature-style aquascapes.
Taxonomy
- Family: Acanthaceae
- Genus: Hygrophila
- Scientific name: Hygrophila lancea 'Araguaia'
- Common synonyms: Araguaia
Habitat
Hygrophila is a genus of Acanthaceae from tropical Asia and Africa, occurring in marshes, river margins and seasonally flooded plains. The genus contains both robust stem species and small creeping forms. In the Aquairi knowledge base, populations associated with this form are recorded from South America.
Growth requirements
- Lighting: high
- CO2: recommended
- Temperature: 22-28 °C (72-82 °F)
- pH: 5.5-7
- GH: 2-10 °dGH
- Substrate: nutrient-rich aquasoil
- Maximum height: 20 cm
- Growth rate: medium
- Recommended placement: midground
Placement
Stem species form quick background bushes; smaller forms (Lancea, Pinnatifida and similar) sit in the midground or attach to wood as facultative epiphytes. In the Aquairi knowledge base this form is recommended for the midground under high light with pressurised CO2 injection, using nutrient-rich aquasoil.
Propagation
Propagated by cuttings and by lateral shoots from the base; rhizome-attached forms divide easily. Documented propagation techniques for this entry include: stem cuttings.
Common issues
Rapid stem species can shade slower neighbours; regular trimming and replanting tops maintain healthy bottom growth.
Propagating Hygrophila lancea 'Araguaia'
Overview
Hygrophila is a genus in the family Acanthaceae and is one of only two genera in its family that contains aquatic plants; its members occur as both aquatic and terrestrial plants across the tropical and subtropical world. Hygrophila lancea 'Araguaia' is a cultivar with narrow lanceolate leaves marketed for the aquascaping hobby. As a medium-difficulty plant it usually needs CO2 injection and moderate to strong lighting to thrive, and its low position in the layout means light reaching it is often lower, so growth is slower.
Propagation Method (Cuttings)
Like other Hygrophila, this plant can spread through plant cuttings. Propagation follows the standard stem-plant routine: cut a healthy top, replant it, and let the remaining base put out side shoots. Cultivars propagate the same way as the parent species, so no special technique is required.
Step-by-Step
- Select a healthy stem showing good coppery-red colour at the top.
- Cut the top 5-10 cm just below a leaf node.
- Strip the lowest pair of leaves so the bare node can be buried.
- Plant the cutting into nutrient-rich substrate, leaving space for its compact form to fill in.
- Leave the original base; it branches and sends up new side shoots over time.
Conditions for Healthy Growth
As a medium-category plant, Hygrophila 'Araguaia' usually requires CO2 injection and moderate to strong lighting to thrive. Strong, stable light and CO2 are what bring out the warm coppery-red to orange colour; in dimmer positions it grows slower and greener. Pair this with nutrient-rich substrate and consistent conditions for the best results.
Trimming & Maintenance
Because growth is slow, trim only as needed: top the leading stems, replant the cuttings, and let the bases branch. Stable, consistent CO2 and nutrient levels are important for success, so avoid drastic changes between trims.
Common Challenges
The main difficulties are its slow pace and its hunger for light and CO2. In a low, shaded midground position it can stall and lose colour, and unstable CO2 or nutrients set it back. Keep conditions steady and light strong, and propagate patiently from a small number of healthy tops at a time.
