Dennerle - Alternanthera reineckii 'Red'

Alternanthera reineckii 'Red' is a classic red aquarium stem plant that develops shades from brown-red to cherry red across both the stems and leaves. Its strong colour makes it a reliable focal plant for Dutch-style layouts, nature aquariums, and mixed planted displays.

Good lighting and a dependable supply of CO₂ and nutrients help maintain compact growth and vivid colour. The plant responds well to regular trimming, and healthy cuttings can be replanted to build a fuller, bushier group through the midground or background.

Plant Profile

Important Note

This plant is supplied in Dennerle’s Plant Bag format, where the plant is rooted in a coconut/coir plug held in a net pot. Unlike traditional rockwool-grown aquarium plants, the plug does not need to be removed before planting. Simply remove the plant from the outer packaging, rinse gently if needed, and plant the coconut plug directly into the substrate. The roots can continue growing through the plug and into the surrounding substrate.

Please note: As this is a living plant, size, leaf shape, colour, and fullness may vary slightly from the product images and between individual specimens. Some emersed-grown leaves may change as the plant adapts to submerged aquarium growth.
