Looking for help with a tricky north GA flower bed

Hello! Total newbie here. Trying to spruce up this struggling flowerbed in front of my house in the Atlanta, GA area (zone 8a). The house is northeast facing (more north than east) and this area is usually shaded by noon. I would like to plant something that will last as much of the year as possible and am open to flowers or shrubs (or really anything that will stay alive). Also want more height – ideally eventually up to the bottom of the front window. The only plant that has done well there is the Hydrangea Macrophylla. I’ve tried azaleas and Joe pye to no avail…. Any help is appreciated! 💚
