This Variegated Japanese Rush is actually not a true aquatic plant, but can survive for up to a year completely submersed in water!
The Variegated Japanese Rush resembles the true aquatic Japanese Rush, but has long grass-like leaves that usually have 2 or 3 white stripes along each light green leaf. The leaves are tough and leathery and will grow to a maximum height of 14 inches (35 cm).
Since it is not a true aquatic plant, the Variegated Japanese Rush does better in tropical aquariums where about half of each leaf is above water. It will grow in many substrates and the roots are thick and are quite capable of taking nutrients directly from the water. The Japanese Rush propagates by producing shoots from the base which will eventually spread and create their own plant.
