Look at Dryopteris and Asplenium, both of which don't object to dry shade. I also like Polystichum and Polypodium.

Great plants, so useful and varied. I particularly like dryopteris erythrosora which is evergreen, the new fronds bronze, and polystichum polyblepharum, also evergreen, the leaves of which are glossy.

Not all the varieties of those are evergreen though Spritz, my polysticum setiferum and dryopteris felis mas both disappear in winter.

look at those that are also british natives they will be the hardiest.

Thanks everyone. I've chosen a nice mix of dryopteris and polystichum and am looking out for a d. erythrosora. I think they'll all look lovely. Thanks again.
