Pulmonaria start off pink and change to blue.
Lots of roses change colour as the flowers age.
So I don't really see why it is that novel to be honest. From a science point of view, it just seems a waste of biotechnology. I understand engineering crops to make them pest/ disease resistant or to express higher levels of vitamins. Things that will have an impact on world hunger etc. But a petunia that changes colour when you give it alcohol? Don't get it at all.
