(1) Margaret made me mark the "single waterlily" seedling yesterday.
(2) It is a seedling of a waterlily crossed with a waterlily. This proves you are just a gene or two away from open center flowers despite all your efforts.
(3) On second thought, it is sort of a pretty flower.
(4) Usually, when Margaret likes something, many other people will like it too and this one may have a future.
Stems not all that dark and I believe center is standard yellow. Neither picture is all that good. It is very bright.
