Short Description

This has to be one of the most well known plants available for the aquarium. They are just as happy in a coldwater tank as being in a tropical tank. It is believed that they secrete a chemical which suppresses algal growth and they also serve to make a beautiful backdrop to the tank. In some areas they have been banned from sale as they are very invasive, taking over areas of water ways and choking the local flora in the process.
