Oh my aching back! I can feel the 'big one' coming on. Judging from the pictures it looks like I have about the same space to cover here with my slope. I do have some tree branches shading the area, so I hope that will not harm the daylilies. This slope has been a real pain for me for nearly 20 years, and I even bought a self-propelled lawn mower for it. But even that slides side ways. I just went out and took a picture of the area where it runs down to the roadway. It has about a five foot drop at about a 40 degree angle and runs almost 50 feet in length. I am concerned about too much shade, but maybe I could try a few plants at a time to see how they do. Here is what it looks like.
