I would like a suggestion for a soil erosion ground cover. I live on a lake and this area has a steep slope going down to rip-rap that extends into the water. This area is in direct sun and the soil is dry clay. I was wondering if English ivy would have a deep enough root system to hold the soil? Would lily of the valley be an option. Thinking of what plants I have available since this is a large area to protect. Thank you for any suggestions,
