We have a guardrail that runs along the front of our property for a distance of approx 200 feet. ( This is over 400 feet away from our house- our house is set back from the road, with woods in front) We would like to plant an attractive, low maintance ground cover out there so we don't have to continually mow or weedwack. I have been looking at planting crownvetch but not sure.. any ideas? Thanks
