For that slope, I’d definitely terrace it like this with low retaining walls—it helps with erosion and gives you flat planting zones; then fill it with a mix of groundcovers, perennials, and some grasses so it looks full but stays low maintenance, it’s way more stable and visually interesting than just planting straight on the slope, check out this render https://app.neighborbrite.com/s/qpRNP8kSeIL
