I would kind of like to see flowers. Since Lily Pad makes distinctive flowers, I would imagine its offspring would too, esp. when mixed with white. Otherwise I'm really not seeing the Lily Pad in that picture.
In a sense it's interesting because you would have parentage with 3 different flower colors; dwarf, shrubby and giant solitary forms all in the blender. I don't see why it's not possible (and wherever there's a Lily Pad, I would imagine there might be a haworthii) but I would be suspicious it's just a made up (invented, imagined, or presumed) name.
