Hi I really need some advice for a quite a large flower bed that sits alongside the driveway to our house. It's around 6/7 metres long, max 2 m wide at its widest point. It's a South facing drive and the soil is very clay and quite lumpy. We have just had the bed cleared of wildflowers that I planted from seed during covid and just went crazy but not in a good way! I need to plant soon so something suitable for autumn planting. It would be nice to have a mix of a few different plants that are low maintenance and look nice all year round. Flowering in Spring/Summer would be nice but not essential. I've attached a photo. Thank you!
