One good place to buy hardy hybrid water lilies adapted for southern areas is:
http://texaswaterlilies.com/Hardywaterliliesorderpage.htmlProper sizes and varieties hybrid water lilies are hard to beat for great shallow water fish refuge areas and as a bonus - aestetics. Lilies also use available nutrients and compete against FA and some rooted vegetation. Artificial cover does not act as plant competition for space and nutrients. As you select named hybrid lilies, keep in mind to notice the size of each variety. Smaller ones and dwarfs stay shallower at a smaller size with slower spread, whereas the large varieties grow deeper and tend to spread faster. Mediums are somewhere in-between.
