Answers:
Colour is the key!
Find yellows and purple flowers ,every year I try to find complementary colours for my garden, one year I have pink and white, the next I have mauve and purple , this year I have yellow and purple in one area in my flower boxes are the reds and white Petunias .

Then don't forget the Wave Petunias they bring music just looking at them trailing down the flower pots!
Have a wonderful Summer!
