Some years ago, my husband and I decided to replace our barbecue kettle with a gas grill; but the kettle was still perfectly good. It seemed a shame to get rid of it. We considered drilling holes in the bottom, and turning it into a planter.
Instead, we painted it bright red and set potted plants and flowers in it. Because it had wheels, it could be moved to the shade. It could be moved where it was raining (or where it wasn't), etc.
It was so cute, we decided to do the same thing with our old chest freezer to complete the whimsy. We drilled holes into the bottom, planted geraniums, and set it next to the BBQ-planter. People always commented on how fun it was when they were on our patio.
