Any suggestions on my plan for this border please?

I have been trying to make a new border. It was mainly filled with orange crocosmia and weeds before. There are orange crocosmia all over the garden so it was overkill.

I have a rough idea of what to do but would appreciate any suggestions from the more experienced gardeners here. I have already ordered the rose, but could place it elsewhere if necessary. I have taken the ideas from a garden magazine.

I can't totally remove the ivy as the wall is too unstable there.
The position is basically sunny, the wall runs exactly from north to south but in the evening it is a bit shaded by trees.

I am still preparing the ground, there is a lot of stone from the wall which I have been removing, but perhaps some should be left in. Last autumn I added some soil improver. The soil is basically good, though slightly sandy and slightly alkaline. Nevertheless it is in a mess right now. The edge is also messy and not defined.

The space is deeper than it appears on the photo (!); the wall is tall, and there is lots of room behind the hebe and also not in shot where the edge curves round.

Thanks for ANY help :)
