Ground Cover - South Facing Steep Slope
We have a slope in front of the house that is difficult to mow and boring to look at. We removed the grass from one part last year and planted some Winter Jasmine but the slope looks terrible and needs some ground cover to prevent erosion and to improve its appearance. We thought about retaining walls, but don't have the money to spend to get the look that we want.
We are having a very hard time finding an appropriate ground cover. We would like to find something reliably evergreen, fast growing (it is a relatively substantial area), that is drought resistant since the area gets strong sun virtually all day, and will tolerate acidic soil. Our soil is clay, but the slope and the sun keep it fairly dry. We do not care if it flowers, only that it will be able to tolerate those tough conditions.
Our top choice thus far is "Homestead Purple Verbena" but it seems questionable whether it will be evergreen in Z 7. I can't imagine it would stay evergreen in a very cold winter like we are having this year.
It is too bad that we don't have the money to create the stone retaining wall of our dreams :). In the meantime we have to deal with this hill that is an eyesore smack-dab in front of our house. Any suggestions would be greatly appreciated.
