I have a 55 gallon with co2 and 4 wpg. I bought two lilies awhile ago not sure which type they are. One has redish green leaves (no patterns) it had a bulb, and the other is green with rich red lines all through it, that one had roots. They cost $40 combined. They are growing great and getting really full. I would like some more for the other end of my aquarium. I did not want to spend alot more money for a Few more lilies. With my other plants I just cut a piece off and plant it and It would grow great. I tried that with the lilies and the parts I planted just die without growing or rooting. Anyone know what the trick is to get more lilies from the ones I already have?
