I found this photo via Apartment Therapy, and thought It was a great idea.
I am the type of gardener that I need immediate gratification, I like everything to look over grown, and I really don't like the way fresh flower beds look spaced out.
These are just full plant trays straight from the nursery. They are set down into the deck for a nice clean look. I am sure they need lots of watering, so as to not dry out in the small plastic containers, but I think with this display there could be so many options.
