Vallisneria giganthea Rubra is the red-bronze form of giant Vallisneria, producing very long, broad ribbon-like leaves that develop warm reddish-bronze to olive-red tones alongside bright green, creating a more colourful and visually dramatic background than the all-green standard giganthea form. Under good light the red tones are most pronounced on newer growth.
It shares the same easy, tolerant nature as all Vallisneria varieties — growing without CO2 in low to medium light and tolerating a wide range of water conditions including hard and alkaline water. It is a vigorous grower and spreads by runners to form an impressive colony of tall, coloured leaves across the background of a large aquarium.
Best suited to large aquariums from 150 litres upward, Vallisneria giganthea Rubra creates one of the most striking large-scale background effects available in the freshwater hobby. The combination of giant leaf length and warm reddish colouration makes it a dramatic and unusual choice for hobbyists wanting a statement background plant in a well-established larger aquarium.
