It's a strange sight for me. When I saw it, I didn't identify the objects as water lilies. Here's one of the values of your photo for me, @velimir. Even if I know it by your indication, they continue to produce a strange sensation for me, accentuated, I think, by their shape and by that lively green. The effect of the reflection of the ceiling (of a nursery, I suppose) in the water, where you can even notice clouds, with its color (which gives it depth), makes good contrast also by the circular shapes. Thank you for sharing.
