PLANT OVERVIEW

About Corkscrew Vallisneria

A twisted-leaf val that makes a tight, grassy background.

Corkscrew Vallisneria spirals its ribbon leaves into tight curls, forming a shorter, denser background than the tall vals. It's an easy, fast, low-tech grower that spreads by runners and tolerates hard water well.
