Hygrophila pinnatifida

Hygrophila pinnatifida

Introduction
Hygrophila pinnatifida is a striking stem plant native to India, valued for its deeply lobed, fern-like leaves and unusual growth habit. Its bronze to reddish tones add texture and contrast, making it a favorite in aquascapes that balance wood, stone, and carpeting plants. “Wildform Hygrophila pinnatifida often develops striking red flecks and marbled patterns across its lobed leaves, a natural pigmentation that adds depth and character to the aquascape.”

Plant Profile

• Type: Stem / Epiphytic-capable plant

• Origin: India

• Position: Midground to background, can attach to wood/rock

• Growth Rate: Medium

• Lighting: Medium to high

• CO₂: Recommended for best color and compact growth

• Height / Spread: 4–12 in (10–30 cm) tall, 4–8 in (10–20 cm) spread

• Water Parameters: pH 6.0–7.5 · GH 3–10 · KH 1–6

Care Summary

• Can be rooted in substrate or attached to hardscape with thread, glue, or mesh.

• Trim regularly to prevent leggy growth and encourage bushier, lateral shoots.

• Adaptable but may melt if parameters swing suddenly; new growth usually rebounds with stability.

• Provides excellent contrast in color and texture, while also offering cover for shrimp and small fish.

• Suitable for paludariums — grows well emersed in high humidity with strong lighting.

Q&A
Q: Can Hygrophila pinnatifida grow without CO₂?
A: Yes, but growth will be slower and leaf color more subdued. CO₂ ensures compact, vibrant growth.

Q: Why does my plant sometimes grow sideways?
A: This species often sends creeping stems along hardscape before growing upright, especially when attached to wood or stone.

Q: How do I keep its reddish tones strong?
A: Use medium to high light, stable CO₂, and consistent macro/micro fertilization. Lower light results in greener leaves.

More About Hygrophila pinnatifida
This species originates from fast-flowing streams in India, where it often grows attached to rocks and submerged wood along riverbanks. Its distinctive, deeply lobed leaves allow it to withstand current while still providing habitat for fish and invertebrates. In the wild it may form emersed growth during seasonal changes, developing slightly different leaf shapes above water.

In aquascaping, Hygrophila pinnatifida is prized not only for its unique leaf form but also for its versatility — it can be used rooted in substrate, trailing across driftwood, or cascading from rockwork. Its natural associations in Indian streams often include small barbs, loaches, and shrimp that shelter among its textured foliage.
