Sounds like.an ideal spot for Mediterranean type planting in gravel. Taxus varieties......slow growing narrow like Stamdishii, low mounds like Coppershine...Juniperus Sulphur Spray.
Phormiums, dwarf purple berberis, santolinas, thymes, euonymous Emerald n Gold. Etc low growing bright blue rosemary too.
A couple of grasses and how about some heathers for winter colour.
Mounds, spikes and scent and easy care ...for.me.
