Description
Plant Profile
Hygrophila Lancea ‘Araguaia’ is an uncommon, highly distinctive aquatic plant named after the Brazilian river system from which it originates. While its appearance resembles that of a traditional stem plant, it naturally grows in compact, short bushes that create a lush, spreading bush effect in the midground of your aquarium. When grown submerged and kept under proper conditions, its foliage develops a rich reddish-brown to deep pink coloration with a distinct light central vein.
*Form Notice: Photos display this plant in both its emersed (above-water) and submerged forms. Depending on nursery availability and seasonality, you may receive this plant in either form. Learn more about what to expect by reading our guide on Emersed vs. Submerged-Grown Aquatic Plants.
Key Features & Benefits
Compact, bushy growth habit stays low to the substrate, making it an ideal midground hedge or accent plant.
Slender foliage turns a deep reddish-brown and pink under strong lighting, offering warm color depth and distinct leaf texture.
Produces vibrant purple flowers when cultivated in an emersed terrarium or paludarium setups.
Care & Planting Instructions
Remove lead weight and cotton wrap (or foam) surrounding the base, then strip the lower inch of foliage so bare stems anchor cleanly into soil without rotting.
Use fine-tip pinsettes to push individual stems 1 to 2 inches into substrate, spacing them about half an inch apart to allow light to reach lower branches.
Provide high-intensity lighting. While CO2 injection is optional, it is strongly recommended to achieve rich reddish-brown coloration and compact growth. See our guide to growing red aquarium plants.
Maintain stable water parameters and supply balanced liquid fertilizers and iron supplements to support healthy leaf development.
Trim stem tops or cut lateral side shoots with straight scissors to encourage low, horizontal branching and propagate new stems. Read our trimming & propagation guide for details.

Frequently Asked Questions
1. Why are the lower leaves falling off my stem plants?
Lower leaf loss (leggy stems) usually occurs when lighting cannot reach the bottom of the plant due to overcrowding or shading from larger plants. Spacing individual stems slightly apart during initial planting and maintaining strong light penetration will keep lower leaves healthy.
2. How do I get my Hygrophila Araguaia to turn reddish-brown and deep pink?
High light intensity paired with consistent iron dosing and micro-nutrient liquid fertilization triggers Hygrophila Araguaia to produce rich reddish-brown and pinkish tones. Under lower lighting, the plant will lean more toward dark green or brownish-green.
3. How do I transition Hygrophila Lancea ‘Araguaia’ from emersed to submerged growth?
When transitioning from emersed to submerged growth, plant bare stems securely into rich substrate under high lighting and keep water parameters stable. As new growth adapts, the plant will shed its land foliage and sprout slender, colorful underwater leaves. Once new shoots take hold, trim away old lower growth to encourage low, bushy branching.
