Vallisneria - Gigantea

Vallisneria americana var. gigantea is a submerged aquatic perennial with long, slender, ribbon-like green leaves. This species grows in temperate regions the world over, forming lush, underwater meadows in rivers, lakes, and ponds. Not only does this fast-growing plant promote natural filtration, but it is also an excellent oxygenator, and provides welcome shelter for all kinds of aquatic life. Vallisneria americana var. gigantea is best grown in groups of several bunches placed close together in pond baskets, in a sunny position. Take care when planting so as not to crush the sensitive, thick white roots, and be aware that this plant may soon start to shade out other species if not kept in check; for this reason it really is best suited to larger ponds only. Occasionally the plant will send up flowers - male and female on separate plants. The female flower is produced on a long twisted stem at the water’s surface, and the male flower on a short stalk near the bottom of the pond.
