Scientific Name: Alternanthera reineckii

Common Name(s): Scarlet Temple, AR

Defining Characteristics: 

• Intense red color: The defining trait; leaves (especially the undersides and new growth) display a deep red to purplish-red color
• High light is crucial for achieving and maintaining the vibrant red coloration. Low light causes the plant to turn green and "leggy."
• Requires consistent dosing of micronutrients, especially Iron (Fe), to ensure deep red pigment production. Deficiency results in pale or pink growth.
• A stem plant that grows vertically and densely; easily propagated by trimming and replanting the tops
• Primarily used as a dramatic red focal point in the midground or background of the aquarium, often featured in tanks for color contrast

Tank Position: Midground to foreground 

Growing Conditions: Submerged or Emersed. This plant should be planted in a nutrient-rich substrate in order for it to maintain its vibrant colors.

Temperature Requirement (°F): 72-82°

Lighting: Low to Bright. Bright light will really bring out the stunning colors of this plant.

Water pH: 6.0 - 8.0 

CO₂ Requirements: Low. CO₂ supplementation is not required but will result in more vigorous growth and colors.

Growth Rate: Moderate

Height at Maturity: Up to 12+ inches

Origin: Central / South America

Regional Locality: Found in tropical and subtropical wetlands, riversides, and in moistened areas due to flooding caused by rains.

USDA Hardiness Zone: 8-11

Suggested Vivarium/ Animal Terrarium Use: Colors show best grown submerged, but the plant will also do well in paludariums / vivariums that have significant water feature or consistently moist conditions.

Care Notes: Alternanthera reineckii is an excellent beginner plant due to its hardiness and adaptability. To create a bushier appearance, regularly trim the top portions of the stems; these cuttings can be replanted to easily propagate new plants. It pairs well with most other common aquarium plants.
