I live in SC where we have hot, humid summers and increased periods of drought over the years. I just bought a new home where most of my lawn is shaded and already has a good deal of moss.

For environmental reasons, I want to turn my lawn into all moss, but understand moss won't grow in the areas of direct sun. I have read that irish moss will, but it isn't really a moss. I am also not wanting to have to water the lawn, which irish moss would require.

Any suggestions on a moss I can put in the full sun or does that just not exist?
