Description
This large, strong Vallisneria is labeled by Dutch water plant nurseries as Vallisneria spiralis "Leopard", but in our opinion it is Vallisneria australis "Marmor" ("Marble"). This selection of the Giant Vallisneria develops up to 1 m long leaves with a pattern of brown, short horizontal lines and, good lighting provided, red-brown coloration.
Vallisneria and its several selections, known as "Vallisneria gigantea" or "V. americana", is an easy, robust aquarium plant that benefits from a nutrient-rich substrate. Medium lighting is sufficient, but with too little light the leaves stay rather green. CO2 addition is not necessary but enhances the growth. The Giant Vallisneria, native to the southern and eastern parts of Australia, also grows at temperatures below 20℃ in unheated tanks. The plant spreads by runners. With its very long leaves, it should be used for corresponding large aquariums.
Vallisneria australis "Marmor" forms lush thickets and look best in at least 50 cm tall tanks in the background. With its floating leaves at the surface, it provides a natural look e.g. to river biotope tanks.
