When I realized that moss is about the only green thing I have right now as well, I began to look at it a little differently too. I'm not sure how it will look during the long drought of summer, but I think an effort to grow more of it is worth giving it a try. At least I know it won't die out, but might look as brown as everything else during that hot dry time. I'm going to do the butter milk thing in my shadiest areas.
I hope you do try; we'll just send each other good luck wishes when it's hot this summer!
