Dwarf Amazon Sword

Echinodorus parviflorus

aquatic plant

Echinodorus parviflorus is a popular aquatic plant native to South America, commonly used in freshwater aquariums. It features bright green, sword-shaped leaves that grow in rosette formations and can adapt to various water conditions. The plant is valued for its aesthetic appeal and ability to improve water quality while providing shelter for aquatic life.

Growing Conditions

☀️

Sun: Moderate to bright lighting; 8-10 hours of aquarium light daily (6500-7000K color temperature)

💧

Water: Thrives in soft to moderately hard water (2-18 dGH). Temperature: 72-82°F (22-28°C). Prefers stable water conditions with regular water changes of 25-30% weekly. Tolerates both still and slightly flowing water.

📏

Spacing: 6-8 inches between plants inches

📅

Days to maturity: 30-60 days to establish; 4-6 months for full maturity

🌱

Planting depth: Plant rhizome (base) in substrate, keeping crown above substrate; roots will develop downward

Soil

Type: Aquarium substrate (nutrient-rich aquatic soil, sand, or gravel)

pH: 6.0-7.5

Amendments:

Aquarium fertilizer tabs Liquid fertilizer (macro and micronutrients) Iron supplements for leaf coloration

Growth Stages

Acclimation

1-2 weeks

Plant is recently introduced to aquarium; leaves may appear stressed or discolored

Maintain stable water parameters, avoid drastic changes. Monitor for algae on leaves. Continue regular lighting and water changes.

Establishment

2-4 weeks

New roots develop from rhizome; existing leaves stabilize in color; slow leaf growth begins

Ensure rhizome is properly seated in substrate. Begin fertilization program. Check for and remove decaying old leaves.

Vegetative Growth

8-16 weeks

Rosette expands with multiple new sword-shaped leaves; plant increases in height and width

Apply regular fertilization (NPK and micronutrients). Maintain consistent lighting and water temperature. Remove any yellowing or damaged leaves.

Runners and Propagation

Ongoing after maturity

Mature plant may produce runners (stolons) with daughter plantlets attached

Allow runners to develop roots before separating. Can leave attached for fuller appearance or separate to propagate.

Full Maturity

Indefinite with proper care

Plant reaches 4-8 inches tall with full rosette; bright green coloration; may flower in emersed conditions

Continue routine maintenance. Prune older outer leaves to encourage new growth. Maintain stable conditions to prevent melting.

Companion Planting

Plan your garden →

Plant with:

Anubias Java Fern Cryptocoryne Ludwigia Rotala Vallisneria Alternanthera

Avoid planting near:

Large algae-eating fish that uproot plants Goldfish (they uproot and eat tender plants) Plecos that grow over 6 inches (may damage leaves)

Common Pests

Remove manually or use snail-eating fish like Assassin Snails. Reduce overfeeding to control populations.
Reduce lighting duration to 8 hours. Perform more frequent water changes. Increase plant density to compete with algae. Use algae-eating fish or manual removal.
Remove affected leaves immediately. Improve water circulation and quality. Ensure adequate lighting and nutrients to strengthen plant.
Plant more securely or use plant weights. Choose compatible fish species or move plant to different tank section.

Uses

🏠

Aquarium Decoration & Landscaping

Household

Dwarf Amazon Sword is widely used in freshwater aquascaping to create natural-looking planted tanks. Its moderate size and bright green color make it suitable as a mid-ground or background plant in various aquarium layouts. [source]

🦋

Fish Habitat & Shelter

Wildlife

The dense rosette of leaves provides excellent shelter and spawning grounds for small fish, fry, and aquatic invertebrates. It creates a naturalistic environment that reduces stress in captive fish. [source]

🏠

Water Filtration & Oxygenation

Household

As a rooted aquatic plant, Echinodorus parviflorus absorbs excess nutrients (nitrogen, phosphorus, potassium) and produces oxygen, helping maintain water quality and reducing algae growth. [source]

🏠

Aquarium Hobby & Education

Household

Popular among beginner and experienced aquarists, this plant is used to learn plant care techniques, nutrient management, and environmental biology in aquatic ecosystems. [source]

Harvest Tips

This is an aquatic ornamental plant, not harvested for food. For propagation: allow runner plantlets to develop 3-4 roots before cutting from mother plant. Best propagated when mature plant is vigorous. Trim outer leaves periodically to encourage bushier growth.

Fun Facts

🌱 Echinodorus parviflorus can grow in both submersed (underwater) and emersed (above water) forms, adapting its leaf shape and structure depending on growing conditions—emersed leaves are typically narrower and longer.
🌱 In the wild, this plant grows in slow-moving rivers and tributaries of the Amazon Basin, which is why it thrives in aquariums with gentle water circulation.
🌱 The plant's name 'parviflorus' means 'small-flowered,' referring to its tiny white flowers that only appear when grown emersed or partially emersed above the water surface.
