🌿 More About Alternanthera reineckii ‘Rosanervig’
In its native South American range, Alternanthera grows along slow rivers and marshy banks where seasonal flooding shifts it between submerged and emersed forms. The ‘Rosanervig’ variety is known for its dramatic variegation, with pink veins marking each leaf in sharp contrast to green and red tones.
These dense stands provide shelter for fry and smaller Amazon fish in calmer margins, while aquatic insects and invertebrates graze among the stems. In aquariums, ‘Rosanervig’ serves the same ecological role — adding structure and cover — while also delivering the vivid splash of color that makes it a signature accent plant.
