We have a slope next to our driveway seen in the pictures. We have a difficult time growing grass in this area. Year after year we are planting seed. I would like to dig up much of the grass and replace it with perennials/trees. I am at a loss what to plant in this area. It is full sun throughout the day. I am just wondering if you have suggestions on what to plant and what would look good together that I will get color throughout the summer. I appreciate you insight:)
