   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.

Hello Aquarists...I have 2 bunches of Japanese Rush I have had since I set up my Aquarium. I have discovered the Rush will naturally died back. Keeping my eye on the plants, they are a sparce variety and great for filling those larger spaces which require just a grassy plant or two. My Aquarium is now 3 months old.

is there any special features of this plant that could help fresh water or tropical fish

    It is a bog plant, so does have special considerations in the aquarium. Of course, many fish do well with a planted environment. Plants create places to hide and retreat, and this plant would do the same. But because it is a bog plant, part of it needs to be out of the water. If you are putting together a vivarium, it can be a super addition. This is an aquarium that has an area for fish, but also has an outside area for semi-aquatic life, like frogs and other amphibians. I've seen, and created:) some wonderful vivariums and I would consider it a prime candidate for that type of environment. I also think it could be used effectively in an aquarium for Rainbowfish, Archers, Labyrinth fish like the Betta and Paradise Fish that look for insect prey above the water surface. It would be a very natural addition for these. My two cents worth:) But I'd love to hear other people's ideas on its aquarium uses too!

The description here says it will live up to a year submersed in water. I got 3 bunches of this after being told (mistakenly, by store employees) that it was a fast-growing, easy aquarium plant. All three bunches were dead (rotting from the bottom up) within a month. I was very disappointed that these were sold as aquarium plants as they did not do well at all. I do not recommend these for an aquarium. Perhaps they would grow well at a pond's edge, above the waterline, but I do not know.
