I have found a few particular plant species to be really hardy, even in low tank lighting. Elodea Densa, Vallis Spiralis, Anubias, Java Moss Balls and Hornwort are some of my favourites, and I have had them in all of my tanks at some point (they are all widely available). My favourite is probably the twisted Vallis, it looks nice when kept in sections together and I would highly recommend it!
