We've mentioned the rose relation to red before - Rossi, Rosy, Russia, Rusalka and so on. In this case Rosicrucian and Rosy-Cross also spring to mind.
I also have a cool picture to go with this one as well. It looks like a medieval image, but it's actually from a wall-painting by the 19th century Czech painter Mikoláš Aleš. I like this image a lot <3
It's titled Lords of Rose.
