Corkscrew Vallisneria
Corkscrew Vallisneria or “Vallisneria Torta” is a very attractive, yet hardy and undemanding plant that is ideal for the background of the small to medium aquarium. It can grow up to 20 inches tall and it provides valuable refuge for timid fish and fry, which will actually encourage those shy species to venture into the open more often. For a healthy corkscrew Vallisneria, plant it directly into the substrate, making sure not to bury the leaf base (crown).
