Probably is the same thing. I know that Mondo grass isn't a aquatic plant. It will last several months in the aquarium but it will eventually die. I have no clue why stores/vendors sell this plant among other none aquatic plants as "aquatic" plants.I have noticed that some plant vendors have mondo grass for sale. I am curious if this is the same type that I have growing in my garden. It looks similar. I am assuming it is not, but it can't hurt t ask.
