hydrangea and wisteria - both have varied flower colors. Both are also seen in Old Southern landscapes. Hydrangea like rich damp soil with filtered sun. Wisteria will seek out light and do well in full sun.
Love this driveway garden: Install Flowerbeds or Plantings: The colors and textures of plants soften a driveways expanse and make it look less utilitarian. Groundcovers and low-growing plants are best in beds along one or both sides of the driveway.
