Planting a Sunny, Dry Slope Above a Retaining Wall: Perennials and Shrubs for Color

For a 90×20 ft south-facing slope above a wall: plant sun-tolerant perennials in loose drifts—daylily, iris, creeping rosemary, mint, rudbeckia, sedum 'Autumn Joy', coreopsis. Add colorful deciduous shrubs: spirea ('Gold Mound', 'Lime Mound', 'Anthony Waterer'), barberry, loropetalum. Backdrop with large sun-loving evergreens. This mix provides year-round interest with minimal irrigation.
