Djjuk, For cascading plants there Helianthemums, alyssum (the yellow perennial), Arabis, osteospermums, convolvulous maritima, verbena homestead purple, Erigeron, and others will thrive. My front wall,has these in abundance for colour from spring to autumn.
Convolvulous cneorum, if you're not in too cold an area, is a womderful silvery velvety plant, sub shrub, with pure white flowers in spring and early summer. Will give height of 3' but cascade too so perfect wall shrub. There are cascading brooms, nepeta, and blue shrubs like caryopteris and ceratostigma for late summer flowering.
Try the not so common abelias like Confetti with its lovely variegated foliage, the euphorbias like silver swan, and the red version rubra. Try a grass like fescue elija blue or stipa Tennuissima for movement and grace. What about the purple pittosporums which will love the sun? Get silvers and greys like santolina and helichrysum, the curry plant, in there.
Yes hebes but euonymous emerald and gold, Lonicera nitida Baggesons gold, ligustrum aurea, etc too. Fuschias like Genii with yellow foliage and red flowers, spireas like goldflame produce orange red foliage and pink flowers.
Consider a eucalyptus like gunnii....pruned annually it produces lovely blue foliage some 6' high annually. Put cotinus royal purple alongside and you have a wonderful foliage association all summer. Consider too Acer Flamingo, a tough beautiful shrub of grey, cream, pink and pale green leaves. I cut mine back to ground level every spring and it makes a mound of glorious colour 8' high every year. It is a real eye catcher and always evokes approving comments.
Not just flower colour but foliage colour, foliage shapes and textures need to be checked out.
I could go on and on as more plants occur to me djjuk but you have an exciting
