Sorry for credit unknown; I love this idea! Back in the the Tulsa Zoo had their service drives planted like this. It artfully disguised the keepers' access lanes while adding the most cooling green to a hot environment.
A lush container garden brings life to the sedate tones of this second-story deck. Flowers contrast with the monotone gray of the house, deck, and railing, but the space retains a peaceful and relaxed feeling. The secret is a well-planned color scheme of mostly green and white, with splashes of yellow and hot pink.
