Tub full of marigolds

We have a couple old bathtubs tucked behind where the sunflowers were. I planted lettuce in them last year and it worked great but this year it didn't take. I decided to mix in some bunny poop and plant marigolds and they seemed to love it. They've been hidden by the sunflowers most of the summer but now that many of the sunflowers are gone the marigolds get their moment to shine.
