'Pink Flavour' has been registered in the RHS Lily Register by The Lily Company and the description seems to match the vendor photos. I have adjusted the database to reflect that 'Iowa Rose' has also been sold as 'Pink Flavour'.
I have added 'Pink Flavour' to the data base so if you have photos you can upload them here:
Lily (Lilium 'Pink Flavour')
I still suspect that 'Pink Flavour ' has had a different name. Maybe someday it will be straightened out but for now there should be no confusion since it now has its own entry.
