Alternanthera Lilacina (Beetroot)

Alternanthera lilacina (often classified as Alternanthera reineckii 'Lilacina') is a popular freshwater aquarium stem plant featuring narrow, long leaves with dark red to deep pink tops and purple undersides. It serves as a striking midground or background accent in aquascaping.

Key Care Requirements

Lighting

• Moderate to high intensity is required to maintain its vibrant pink, red, and lilac colors.
• Low light causes the lower leaves to drop and colors to fade.

CO2 and Nutrients

• Supplemental CO2 injection and a nutrient-rich substrate or liquid fertilizer heavily benefit its growth and coloration.

Water Parameters

• Prefers a temperature of 72°–82°F (22°–28°C).
• Optimal pH level: 6.0 to 7.5.

Placement & Maintenance

• Best planted by separating individual stems and spacing them out in the midground or background.
• Regular trimming promotes a bushy, compact shape.
• Trimmings can be replanted to propagate new growth.
