Alternanthera Reineckii o Rosa de Agua

rosa de agua

Nombre científico: Alternanthera reineckii var. roseifolia

Nombre común: Alternanthera rosa, Rosa de Agua.

Familia: • Amaranthaceae.


Esta planta es procedente de América del Sur. Las plantas cultivadas proceden de Brasil.


Planta de tallo con hojas alargadas y anchas 3 a 8 cm de largo. El crecimiento de esta planta es vertical. El color de los tallos y la parte inferior de la hoja son de color rosa salmón llegando al rojo, el color de la parte superior de la hoja dependerá de varios factores como son la intensidad lumínica y nutrientes, puede ser desde un verde pasando por marrón y en los mejores casos casi llegar a un rosa rojo.

Se utiliza formando grupos que dan color rojo al acuario.

Esta planta necesita una alta concentración de luz, como mínimo 1 watt por litro de agua…

La altura de la planta es de 15 a 50 cm pero puede superar fácilmente esta altura. La anchura de un tallo es de unos 10 a 20 cm.

Forma de propagación:

Por vástagos que crecen desde la base de la planta para producir este tipo de reproducción es bueno estimular la planta con abono de tipos sólido en la raíces aunque en la mayoría de la veces podemos reproducirla por esquejes que se plantan directamente en el sustrato.

Esta planta es una buena alternativa a otro tipos de Alternantheras ya que son plantas con una menor dificultad. Para empezar con este tipo de plantas puede ser una buena elección. El crecimiento de esta planta es lento, si no es atendida puede paralizar su crecimiento. Para un crecimiento pleno se deben cuidar los nutrientes de las plantas, aportación de hierro, la iluminación, y si es posible abonado con co2.


17° a 28°C.


pH: 5.0 – 8.0. Dureza: prefiere agua blanda y ligeramente ácida o neutra.


Alta a muy alta, la planta para ofrecer su mejores colores requiere de la mejores condiciones de luz. Sobre 1W/litro.

Tipo de sustrato:

El sustrato habrá de ser arcilloso y rico en nutrientes y requiere de abonado periódico, preferentemente con pastillas cerca de las raíces. Como todas las plantas es sensible a la falta de hierro, hecho fácilmente detectable por la pérdida de color de las hojas.


Difícil. Esta planta es la ideal para entrar con buen pie en el mundo de las Alternantheras al no tener tantas demandas como otras especies. La planta no crecerá cuando la falta lumínica sea importante (intensidad de 1W/l. al menos) el abonado y un buen sustrato son totalmente necesarios en esta planta.

Una opcion que no puede hacer falta en la colección de plantas de tu acuario….

Debe ser abonado con frecuencia para suministrarle hierro. Asi podra obtener la coloracion rosa. Necesita una iluminacion intensa. Se reproduce por esquejes del tallo.
