Midwinter Fire suckers like mad when it's happy and can sulk when it isn't.
How about choisyas - evergreen foliage, white flowers that smell of orange blossom. Available in deep green or golden foliage forms. Berberis linearifolia Orange King would make a good contrast as it's foliage is much finer. Berberis darwinii is another possibility.
For perennials, have a look at beared iris with orange or white flowers. They will enjoy a well drained sunny position and, when not in flower, their glaucous foliage spikes will contrast well with dark greens and rounded forms.
