Alternanthera Reineckii 'Mini' UNS Tissue Culture

Plant Profile

Alternanthera Reineckii 'Mini', widely known in the aquascaping community as AR Mini, is a compact dwarf cultivar of the iconic South American stem plant. Celebrated for its intense ruby-to-magenta red foliage and stout, bushy growth habit, this mini variant provides unmatched red coloration without towering over smaller setups. Reaching a manageable height of just 3 to 4 inches, its dwarf footprint makes it an exceptionally versatile choice for creating vibrant red foreground carpets, rich midground transitions, or eye-catching focal points in nano aquariums and Dutch-style aquascapes alike.

Tissue Culture cups ensure your aquascape gets a super clean starting point. Lab‑grown and fully sterile, it arrives without pests, snails, duckweed, or any unwanted algae. It’s the go‑to option for anyone who wants peace of mind when adding fresh greenery to a carefully maintained setup.

Key Features & Benefits

• Crimson and magenta foliage adds bold color contrast to foreground, midground, or nano layouts.
• Compact dwarf habit forms dense, low-growing red bushes with minimal height pruning.
• Dense leaf structure gives cover and shelter for dwarf shrimp and timid fish.

Care & Planting Instructions

• Thoroughly wash away the nutrient gel from the roots with your fingers before parting it out into manageable portions.
• Use fine-tip pinsettes to plant small stem clusters 1 inch apart into aquarium soil.
• Provide medium-to-high lighting. Regular dosing of liquid fertilizers such as UNS Plant Food (2–3 times per week) and pressurized CO2 injection are highly recommended to achieve maximum crimson coloration and prevent stunting. See our guide to growing red aquarium plants.
• Maintain stable water parameters and avoid sudden environmental shifts to prevent melting or rotting.
• Trim stem tops or side shoots with curved scissors once stems reach the desired height, and replant trimmings directly into substrate to propagate and thicken the carpet. Read our trimming & propagation guide for details.

Frequently Asked Questions

1. Why are the lower leaves falling off my stem plants?

Lower leaf loss (leggy stems) usually occurs when lighting cannot reach the bottom of the plant due to overcrowding or shading from larger plants. Spacing individual stems slightly apart during initial planting and maintaining strong light penetration will keep lower leaves healthy.

2. How do I keep AR Mini UNS Tissue Culture growing low and bright red?

Providing strong lighting, pressurized CO2, a nutrient-dense substrate, and regular micronutrient dosing with liquid iron ensures intense red foliage while encouraging low, horizontal branching rather than vertical stretching.

3. How do I prepare Alternanthera Reineckii 'Mini' Tissue Culture before planting?

Carefully remove the gel from the roots by washing the plant in a bowl of room-temperature water or gently rinsing it under a tap. Once the gel is removed, separate the dense cluster into smaller clumps or individual stems and plant them into substrate using fine pinsettes.
