I don't follow the rules. At least color rules where the garden is concerned. I just plant what I want. This year I am really into purple and yellow.
Zinnias are one of my favorite flowers. Like real life pincushions.
I do try to avoid putting orange and pink right next to each other. That would clash terribly.
I think you should plant what you like and it is only flowers. You can move them.
Generally, I am a good girl and always follow the rules but in the garden I am a rebel.
