Tici In Vitro Aquatic Plant - Staurogyne Repens

1) Botanical Overview

• Family: Acanthaceae

• Origin: Brazil (South America)

• Growth form: Low-growing creeping stem plant

• Type: Amphibious perennial

Unlike fine carpets, Staurogyne repens is a broadleaf foreground/midground plant that forms compact bushes or low mats.

2) Morphology (Technical Characteristics)

• Leaf shape: Lanceolate to oval

• Leaf size: 2–4 cm long

• Color: Medium green; can deepen under strong light

• Stem type: Thick, creeping stems

• Rooting: Adventitious roots from nodes

It grows more structured and “plant-like” compared to grass or micro carpets.

3) Aquarium Parameters

It is significantly more forgiving than most carpeting plants.

4) Growth Behavior

• Growth rate: Moderate

• Height: 5–10 cm (can be kept lower with trimming)

• Spread pattern: Creeps laterally and branches

• Structure: Forms dense clusters rather than flat lawns

In high light + CO₂, it grows compact and bushy.

5) Planting Method

1. Separate stems into individual shoots.

2. Trim lower leaves from bottom node.

3. Plant stems individually 2–4 cm apart.

4. Allow lateral shoots to fill gaps naturally.

Avoid planting in dense bunches — spacing improves spread.

6) Trimming Strategy

• Trim tops when reaching 6–8 cm.

• Cut above a node to encourage branching.

• Replant tops to thicken carpet.

Frequent light pruning yields the best compact form.

7) Common Problems

Leggy growth

• Cause: Low light

• Solution: Increase PAR

Yellowing lower leaves

• Cause: Nitrogen deficiency or shading

• Improve fertilization and trim top growth

Slow spread

• Often due to weak substrate nutrition

Algae on leaves

• Thick leaves resist algae better than fine carpets, but flow must remain moderate.

8) Aquascaping Uses

Ideal for:

• Foreground in larger tanks

• Midground transition zones

• Nature-style layouts

• Between rock crevices in Iwagumi

Pairs well with:

• Micranthemum tweediei

• Eleocharis acicularis

• Hydrocotyle tripartita

It adds a bold leaf contrast compared to fine-textured carpets.

9) Comparison to Carpeting Plants

10) Pros & Cons

Pros

• Hardy and adaptable

• Thick leaves resist algae

• Suitable for beginners

• Good for both foreground & midground

Cons

• Not a true “flat carpet”

• Requires trimming for compact shape

• Slower to spread than runners-based carpets

11) High-Tech vs Low-Tech

High-tech (CO₂ + strong light):

• Dense, compact growth

• Faster lateral spread

• Richer coloration

Low-tech:

• Taller structure

• Slower fill-in

• Less compact but still viable
