I just thought I would share, this stuff started growing in my tank completely on its own. My guess is that it migrated when I planted glosso (which did not survive). For a time I thought it was glosso and I kept trying to replant it to no avail. Its a beautiful plant, but unfortunately it covers the surface and starves other plants. Also, one interesting note about this plant, I have had severe BBA problem with my tank recently, but somehow this one plant has managed to not get infected with it. Its a BBA proof plant, anyone know how to cross pollinate?
