Maryvonne & Myra--Kishin is one of Garet Uemura's hybrids that he sent me last year. It has been an outstanding performer! Stays a nice compact size & blooms galore. Once I get extras of it, I'll offer it as a trade only plant to see if I can get some other harder to find lilies to add to my collection. Keep your fingers crossed that this winter I don't have the massive losses like I did this past winter.
This style of pond is very easy to do. Just make sure the ground is level. I use old carpet for an underlayment & then the liner once the walls are built. A pond this size will bow out the sides a bit, so if you don't want that to happen you'll need to use posts & cement as a brace on sides longer than the 8 ft. The bowed sides don't bother me, so we've never done it.
Bonnie--my Mayla & Wow are in ponds that get morning sunshine & then shade after 2-3 pm, so not getting full sunlight might be affecting the color.
