I didn't want to move the wrong one so I wanted you to see that if you have any errors in the future, when you are the database entry, you can easily propose the changes or edits yourself.
In this database entry for
Tall Bearded Iris (Iris 'Escape from Boredom') are all the images associated with this plant, click on the image of yours you need moved (as Kent said, you can move it to the correct entry rather than delete it). When you click it, it enlarges it and then you scroll down for the editing functions. Enter the correct name and click on the correct entry and then follow the step to propose the move for admin approval.
