Here you are, Mark!
I do not grow many ferns for sunny location but can contribute with what I have. In fact, I do not grow these ferns, they have chosen to grow with me.
One is the very common Polypodium vulgare. This one spreads moderate with stolons in shallow moss cover on rocks and boulders and tree-trunks.
The other, Asplenium septentrionale, is a small one growing in very dry crevices.
Both tolerates full sun (at least in Norway) but grow in shade too.
