Way back in January when I was out taking pictures ready for World Wetlands Day, I spotted this rather pleasing combination by a neighbour's garden. I loved the contrast of the rich greens of the moss against the bark, berries, box and even the pavement. If you click to enlarge the picture, you can see that there are at least three species there. Just don't ask me to identify them!
Have a look at Mrs Nesbitt's Place for more pictures on the theme of M.
