I am at my wits' end trying to figure out what to plant on a rather large slope above a section of my garden. It is about 70 feet long and 8 or more feet from top to bottom. It is mostly south-facing but enjoys some shade through the day. The slope is close to 45 degrees. The soil is sandy fill brought in when the driveway was installed. Irrigation covers most of the space. Of course I want it to be attractive but low maintenance is my main concern because it's downright dangerous to work there. Weeds are under control but arbutus leaves rain down in profusion from mid-May until September and Garry Oak leaves from September to November. Some plants that have grown there so far and not worked out for various reasons are: Crocosmia x crocosmiiflora, Shasta daisy, Foxgloves and other self-seeded lovelies. Chamaecyparis pisifera filifera aurea and an old prostrate juniper are doing very well - maybe similar small conifers are the way to go? Any comments would be much appreciated.
