I love that one Lynn, I never got around to buying it though. They were very expensive when I got Waterlily years ago, and that increased well (I spread it around) so I guess I felt fulfilled.
They do make a good show, but the other plants around mine start to die back when they flower so sort of spoil the effect. You will have to get some photos of the flowers in the autumn too, I guess you remembered seeing the flowers then, it can catch you out when you don't realise the foliage grows in the spring.
