Good luck with the breeding, and hang in there! Knowing is half the battle, so I think you'll be fine now. I'd recommend checking out the methods in the link I gave you in my previous post to find one that you like. If you just want something simple, there are plenty of methods in that guide that don't require much oversight. The more complicated methods require precise managing of genes and knowledge of the breeding/cloning mechanics, but will get you Blue Roses faster.
Thanks to the power of datamining, we know basically everything about flower breeding now. Like which layouts are the best (for example, the diagonal checkerboard pattern that most of us used in NL isn't a good one) and how exactly the genetics works. If you're also not familiar with the datamining stuff,
I'd recommend checking out some the guides here. They'll help you better understand the different methods I linked to.
Feel free to let me know if you have any more questions. I'm also stubborn and like breeding flowers on my own, so I get it. :'D
