Frank, one of the issues of ADD is the inability to clear my head from things that linger and haven't been resolved. I kept looking back at my lilies, and realized that my Denver hardy lilies were actually Dallas hardy lilies. I bought these 10-11 years ago, and somehow Denver got caught in my head. So, if you do get lilies, avoid the pink Dallas lilies because they can be aggressive spreaders. Peach Colorados, and yellow Charlene Strawns are much slower. They're slow enough that I'm going to split them to plant at other areas of my pond. The Colorados and C Strawns are available at different online aquatic plant stores, but I haven't ordered from any of those. I would Google "Kirk Strawn Colorado Hardy Lily" or "Kirk Strawn Charlene Strawn Hardy Lily" . Both list stores that carry them. Expect to pay around $35 each, and 2 day shipping costs.
