Sea Buckthorn grows like mad round here and is a good screening shrub/tree. You can eat the berries, if you really wanted to.
The other usuals are cotoneaster, guelder rose, and Phormiums.
Fatsia (the bog standard one) does really well if you can shelter from the worst of winds. The various varities of Fatsia will also do well in sheltered spots.
