Well that company must have been really desperate for sale, if they tried to make people think the lilies had actual tree trunks... I thought this usually was more of an exaggerated height reference, but I guess a seller could twist this even further.
Don't worry about the Purple Prince, it's going to be more or less pink... With perhaps just a little purple. Personally I'd love a true purple, O.T., but this is also just marketing and Photoshop.
