I have a west facing wall on our house in Colorado and it gets really HOT and dry. It also faces the street and is a showcase area. Any ideas on interesting vines or evergreen ivys that might like this area? I am building a rock garden across the front of the wall but need some hardy background. The ground freezes here, gets about 5-10 degrees below zero. Thanks!
Dwarf and slow-growing conifers to make a naturalistic backdrop to the rock garden. Planted between the wall and the main part of the rock garden, these may remove the need to have something on the wall itself.
