Description
Plant Profile
Alternanthera Bettzickiana Red, commonly known as the Red Calico Plant, is a bold and adaptable semi-aquatic species native to Central and South America. Highly favored for terrariums, paludariums, vivariums, ponds, and bog gardens, this striking plant features vibrant pink-to-red stems and green-to-yellow leaves that turn a vivid, fiery red under high-intensity lighting. While not a permanently aquatic species, it is often used as a long-lasting temporary submerged display in freshwater aquariums, maintaining its eye-catching colors and developing root systems underwater for several months before benefiting from an emersed recovery period.
*Semi-Aquatic Notice: For permanent, long-term health and growth, it is best grown emersed in paludariums, terrariums, bog gardens, or moist outdoor ponds.
Key Features & Benefits
Bold color palette ranging from green and yellow to vivid pink and deep red.
Versatile semi-aquatic species that excels in high-humidity bog environments, vivariums, and water margin planters.
Provides excellent protective cover and shelter for sensitive fauna species.
Care & Planting Instructions
Remove lead weight (or pot) and cotton wrap (or foam) surrounding the roots, then strip lower foliage so bare stems anchor cleanly into soil without rotting.
Use fine-tip pinsettes to push individual stems 1 to 2 inches into substrate, spacing them so light reaches lower leaves.
Provide medium-to-high lighting for intense pink and red coloration; keep soil consistently moist in terrestrial/emersed setups or maintain high humidity in closed enclosures. See our guide to growing red aquarium plants.
Maintain stable water parameters and avoid drastic environmental changes to prevent leaf melt or stem rotting during submerged periods.
Trim stem tops with straight scissors once stems reach the desired height, and replant trimmings directly into moist soil to propagate new growth. Read our trimming & propagation guide for details.

Frequently Asked Questions
1. Can Alternanthera Bettzickiana Red live fully submerged in an aquarium permanently?
No. Alternanthera Bettzickiana Red is a true semi-aquatic plant. While it will maintain its vibrant pink and red foliage underwater for several months as a temporary display, it eventually needs to be transitioned back to emersed growth (in a paludarium or terrarium) to recover and thrive long-term.
2. How do I bring out the bright red color in Alternanthera Bettzickiana Red?
To turn its green and yellow foliage into a vivid pinkish-red, provide high-intensity lighting along with consistent iron supplementation. In submerged setups, pressurized CO2 injection will also help maintain maximum color vibrance.
3. Why are the lower leaves falling off my stem plants?
Lower leaf loss usually occurs when lighting cannot reach the base of the plant due to overcrowding or shading from upper leaves. Spacing individual stems slightly apart during planting and ensuring adequate light coverage will keep lower leaves healthy.
