One of the things I love about my yard is that it has lots of color during the spring. The down side of that is that there is very little color in the summer. My hydrangea is about the only color in the yard from June - September. I use planters and hanging baskets to bring in some color during this time of the year.
I am not a bit petunia fan, mostly because they are sticky when dead-heading. However, I love that they continue to bloom all summer long. I bought a basket this year with a petunia I love!
