Its wild Verbascum thapsus, Mullein. It seems to show up everywhere dry. I let it grow because its not poison ivy.
I never looked at saxifraga before, really nice. I have one Rosularia plant, I thought they might be good for the recessed areas, need more. I thought foxtail lilies would look good against the dark rocks at the base. I started propagating sedums. I will have to look up the others you mentioned, I'm not familiar with some of them. So happy I can find great plants online, i can only find sedum and a bunch of miss-labeled, drowned chick charms here. Oregon must be plant heaven.
I am going to print out pictures and try to work on the design. My husband wants to work on the stone edge for the raised bed at the base. He's kind of into it, he never saw this area cleared. We have a nice pile of large shale rocks that match the cliff. I'm kind of excited.
