https://wiki.irises.org/TbAthr...
and one I found on a thread.. I'm guessing it's a cellphone picture as they tend to be color enhanced..
The thread "Merian Gardens in Basel (Bâle) Switzerland" in
Irises forum
Different lighting, age of bloom, and cameras all can make a difference in pictures... But you're right, the one in our database looks very different... I don't grow it, so I can't say that it's wrong..
