Dressing up Container Gardens for Fall

I wish I had more time. Truth is, I don't always have time to garden. So, when fall comes, and my pots are starting to sit empty, I fill them with rocks, and free pine cones from down the street. Our neighbors have trees that drop pine cones, so I walk by, take my plastic bag, and load them up. Then, at the end of the season, I burn them in my outdoor fire pit.

What do you do to spruce up your container gardens?

Needs quite a few more pine cones. I only picked up a small amount the other day.
