Although there are some more light tolernt ferns out there, check with your local nursery, mosses need shade and humidity, lots of both. Funny thing is, is that once you go through the work of establishing a fern/moss area then the work afterwards is minimal at best. Trees, rocks, a water feature, all help to satisfy some of each need. Check a website called entwood nursery for some cool info and pointers

Bruce,
I think that you have a lot of work to do. If you really are serious about growing moss and ferns then you will need to engage the help of a landscaping service (I can recommend one in your area-if you wish) and you will have to modify the environment that you want to have mosses and ferns growing in. I mean major modification!

You will need to add small trees and/or structures to create mini-environments that you can exploit to grow the different kinds of ferns or mosses that you may be interested in growing.

The easiest approach to go with just what you have would be to create an extensive bog area as sphagnum moss that grows in a bog will do well in full sun in your area plus if you add carnivorous type plants these too will enjoy the full sun.

Or you can develop a combo plan with a bog area, a water feature, small trees, structures, etc. For a fantastic
garden plan that was done and is probably still in process by a young couple in Quebec check the link below.
