I would go with a mix of low-maintenance shrubs that do well in full sun such as Amber Jubilee Ninebark, hibiscus, Blue Puffball Vitex, and Cobalt-N-Gold Hypericum. Here’s a full list of shrubs that do well in zone 7 gardens. Our soften-a-fence-line project has great suggestions also including Atomic Red Trumpet Vine. Atomic Red will help bring in hummingbirds. Be certain to include a redtwig dogwood for winter interest.
