Hygrophila lancea "Araguaia"

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Its creeping, low-growing habit makes it an exceptional choice for the foreground or midground. Rather than growing straight up, it tends to sprawl horizontally, especially under strong lighting. It looks stunning when planted amongst low rocks or creeping over driftwood.

Botanical form

Stem

It features narrow, lanceolate leaves that grow tightly along a reddish stem. Under optimal conditions, the leaves boast a striking blend of red, purple, and copper-brown tones with a distinctive lighter central vein. The stems grow at angles, branching frequently to create a sprawling, bushy shape.

Growth

Medium

Unlike many of its Hygrophila cousins, 'Araguaia' has a relatively slow to moderate growth rate. It is not an aggressive grower and requires patience to form dense bushes. The addition of CO2 and high light will significantly speed up its growth, but it remains a very manageable plant.

Substrate

High

Hygrophila lancea "Araguaia" has a high substrate demand and grows best in a rich aquasoil that supplies plentiful root-based nutrition. It needs a relatively deep substrate layer of 5 to 7 centimeters to anchor its delicate stems, particularly since it has a creeping, low-growing habit that spreads laterally along the bottom. Adequate soil nutrients are crucial for developing its striking reddish-brown colors and dense, narrow leaves, as it relies heavily on root uptake.

Column fertilization

Recommended

Liquid fertilization is essential to provide the necessary iron and trace elements for its vibrant coloration. Regular dosing ensures the water column is rich enough to support its slow but constant metabolic needs. It responds well to a comprehensive liquid fertilizer regimen tailored for red plants.

Root fertilization

Required

This plant heavily relies on a nutrient-rich substrate for long-term health and stability. An active aquasoil or the generous use of root tabs will promote a strong root system and denser foliage. Good root nutrition is often the key to achieving the deepest red and purple colors.

Trimming

Regular

Trimming should be done carefully to maintain its bushy, creeping shape. Snip the longest sprawling stems at a node to encourage further lateral branching. The cut portions can be replanted to fill out the cluster, though they may take some time to establish and resume growth.

Propagation

Cuttings

Propagation is done by taking stem cuttings, though patience is required due to its slower growth. Cut a healthy stem section and plant it firmly into the substrate. Alternatively, its natural sprawling habit often produces roots along the stem, making division of creeping stems very easy.

Sensitivity

high

It is quite sensitive to poor water conditions, lack of CO2, and insufficient light. If shaded by larger plants, it will quickly lose its color, turn green, and shed its lower leaves. Consistency in CO2 injection and nutrient dosing is required to prevent it from melting or stunting.

Layout role

Foreground, Midground

It acts as a premium, high-impact accent plant in the midground or foreground. Its unique reddish-purple color and sprawling texture contrast brilliantly with bright green carpeting plants or grey hardscape. It is ideal for adding a splash of rare color and intricate detail to nano or nature aquariums.
