Backyards: Your Friend, Moss

Living With Mosses, by students and faculty at Oregon State, has the worthy goal of enhancing "public awareness of the effects and benefits of mosses in our everyday environment." In addition to basic moss biology, the site discusses moss on sidewalks and rooftops, pros and cons of mosses in lawns and gardens, physical and chemical moss control methods, and moss encouragement.
Mad About Moss: The Simple Art of Moss Gardening, from the newsletter of the Brooklyn Botanic Garden, recounts one gardener's bold experience of replacing a lawn with a carpet of moss, lays out the conditions for moss growth, describes how to start and maintain a moss garden, and oh so very much more.
