🌿 Basic Overview

• Scientific Name: Myriophyllum mattogrossense

• Common Name: Mattogrossense Milfoil

• Family: Haloragaceae

• Origin: South America (particularly Mato Grosso region, Brazil)

• Type: Stem plant

🌱 Appearance

• Stem: Soft, upright, and slender; grows 30–60 cm tall.

• Leaves:

  • Finely divided, feather-like whorls surrounding the stem.

  • Each leaf segment is delicate and thread-like, giving a flowing appearance underwater.

• Coloration:

  • Bright light green to yellow-green under medium light.

  • Can develop reddish or golden tips under strong light and good nutrients.

• Overall Look: Creates a soft, bushy, and dynamic texture that sways beautifully in the water flow.

💧 Tank Conditions

🌾 Growth & Maintenance

• Growth Rate: Fast under optimal light and CO₂.

• Form: Bushy and vertical; forms dense thickets with frequent trimming.

• Trimming:

  • Regular trimming keeps the plant full and compact.

  • Cut tops can be replanted to thicken the group.

  • Frequent pruning prevents lower leaves from shading and decaying.

• Spacing: 2–3 cm between stems to allow light penetration.

• Placement: Background plant; can be midground in larger tanks.

🌈 Color & Health Tips

1. Use high lighting and steady CO₂ to maintain lush, bright foliage.

2. Dose micronutrients and iron to enhance color.

3. Keep nitrate moderate (5–10 ppm) and phosphate 1–2 ppm for balanced growth.

4. Maintain strong water circulation to avoid debris buildup between leaves.

5. Avoid algae growth — fine leaves can easily trap detritus.

🧪 Propagation

• Method: Stem cuttings.

• Trim healthy tops (5–10 cm long) and replant directly in the substrate.

• Roots form rapidly, and new growth appears within days.

🌍 Aquascaping Use

• Excellent background or filler plant for adding soft texture and movement.

• Works beautifully in Nature-style or Dutch-style aquascapes.

• Adds a flowing, dynamic element to layouts with rigid hardscape structures.

• Combines well with:

  • Rotala rotundifolia (color contrast)

  • Ludwigia arcuata (shape and tone balance)

  • Hemianthus micranthemoides (fine-textured pairing)

⚠️ Challenges

• Can lose lower leaves if light doesn’t reach the base.

• Sensitive to low CO₂ or nutrient deficiency — may cause dull color or stunted growth.

• Needs regular trimming and cleaning to stay healthy and attractive.
