I've been up at Johns Hopkins again recently for my bothers spine issues. I snapped this shot at the main entrance while I was getting some air. These are giant planters and I just love that they use tall, upright plants in the center, then lower plants, then hanging plants on the edges. I also like how they used contrasting colors and contrasting textures.
I wish it wasnt so hot in South FL. I usually do this exact set up in two planters in front of the house. The sweet potato vines wilt each day though down in FL.
