What flowers for a Fourth of July border in Seattle?
My Shasta Daisies always bloom by July 4th and I want to give them some well-mannered red and blue flowering companions that bloom at the same time. I used to have a scarlet verbena and loved its contrast with the daisies and bluettes. But the bluettes are very invasive and must go.
What blue and red perennial flowers would you plant with daisies for a Fourth of July border?
