Here in the PNW moss grows pretty much everywhere. If you aren't resigned to it growing in the garden, you have an uphill battle on your hands. Personally I love moss. I do pay to have someone treat my roof, because I don't want it growing there. I don't mind it growing in the lawn, or in the garden beds, and I'd love to have lots more of it on all the rocks and stones and boulders in my garden. You may have heard the term "mossback" to refer to a PNWer who prefers drizzly, gray weather rather than sunny days.
I shouldn't have been surprised to find it growing on the cushions of my chaise. Lazy gardener/home-owner that I am, I leave them out all winter. They seem to be made of a fabric that dries out rather quickly once the sun comes out.
