Answers:    The Christmas Fern and Dragontail Ferns are evergreen and perennial. The site below lists some ferns and contained by the description it will tell if they are evergreen or not. They also have pictures for suggestion.

Edit: Maidenhair Ferns are generally not evergreen. Some species will hold their leaves depending on how cold it gets. The Himalayan maidenhair fern (Adiantum venustum) will stay evergreen into the middle or upper teens. There are dozens of species of Maidenhair ferns and it a moment ago depends on the species as to what zone they would grow. I know some will grow into zone 4-5 and as warm as zone 8-9. Not all species will grow within all the zones however.
The most cold resistant fern I know of is the Christmas Fern...I enjoy seen these ferns in the woods when the heat gets down to 15 below zero and colder.
